Just got my car diagnosed today, and two error codes came up.

1) P1300 (Igniter Circuit Malfunction No.1)
2) P1310 (Igniter Circuit Malfunction No.3)

how to i go about sorting this out? All help appreciated! thanks.

You need 2 new coil pack mate

is that all it is? or will i have to change anything else?

try change the coil from the working ones to the non working ones.

2 coilpacks on cylinders 1 and 3?

You can buy coilpacks from Lexus/Toyota or Japarts ebay shop. Japarts sell the genuine Lexus ones for £100 each, they also do the patterned ones for £59 each- check their ebay shop.

Edit: You may have to reset the ECU after installing the new coilpacks.

i have 2 coilpacks for sale under the sale section

I have replaced the 2 coilpacks with brand new ones n its still having the same problem! help please!

Did you definitely replace the right ones ? With number 1 cylinder starting at the front of the car, so you replaced 1 and 3 ?

Are you still getting exactly the same codes ? Does the car appear to be running normally or is it in "limp" mode and significantly underpowered ?

How about the spark plugs, did you check the condition of those, have they been replaced recently ?

as stevie is said. you replaced the right ones as its easy to get confused. check spark plugs or change them.

I've just realised that you're the same guy that posted [url="http://www.lexusownersclub.co.uk/forum/index.php?showtopic=59970"]this thread[/url]. It would probably have been useful to keep all the information in one thread.

Given that you seem to keep having these sort of symptoms it seems unlikely to me to be the coil packs.

What is the story with the plugs, as I asked in your previous thread. Have those been changed recently ? Have you checked to see what condition they seem to be in ?

the plugs were changed around 2000miles ago. so let me get this straight, cyclinder 1 is at the front of the car, closest to the rad etc?

who fitted the plugs????the engines are very tempramental if you dont use iridium plugs.and as asi found out the cars hate the wrong plugs so its worth removing them and checking they are the right ones.
yip cylinder 1 is closest to the rad!

Did this problem only start happening when the plugs were changed ?

What type of plugs are in there (there should be something on the plug which says, if you take one out). Do they look in good condition ? What colour is the tip ?

no this problem started around december time, then stopped until now! the tips of the spark plugs are a gun-metal grey colour

What type of plugs are they exactly ? Not just the make, but the exact model.

So the plugs were changed since this first started happening ?

What else is the car doing, does it seem to be misfiring/running rough ? Is the engine check light actually on at the moment, any other warning lights ?

they are NGK....this was after the spark plugs were changed this problem started happening. no the car is not misfiring or nothing. the engine management light comes on when the car cuts out. then when it starts back up it goes off!

i would remove them and go get other plugs take the plugs out normally iridium plugs have this written on them.
get the proper plug number and see if they are iridium if not remove them throw them in the bin and put proper plugs in!
oh just wondering how much did the plugs cost you?the proper ones are expensive!!!!

ps the number you are looking for is NGK IFR6A11

Is the car cutting out while driving along, or just while idling ?

So everything was fine before the plugs were changed ? Is this the only thing that was done at the time ? Has the cam belt been changed ? Has it had any kind of accident repair at the front end recently ?

the timing belt was changed around 1000miles ago. no it has not been in an accident either. it cuts out while driving along and sometimes when idling.

Did it do it before the cam belt was changed ?

i would change the plugs as ormi said.

There's not a lot of point changing the plugs *if* they're the correct ones and are fairly new though.

well i suppose. maybe try changing them over to different ones e.g. 1 to 2.n 3 to 4.

used to get this problem when changing mondeo plugs the garage i worked for stopped using ngk plugs(platnum) as it gave the same symptoms as killa is having
as said before he will need to remove the plugs and get the numbers and check to see if they are iridium or not then we can go further into diagnosing his fault but until then we cant say no more.

ps the gap might have been closed a bit due to rough handling or could be faulty plugs.

which spark plugs do u recommend then?

The Denso plugs are the other OEM plugs. The standard ones are SK20R11, but I (and many others here) use IK20R11, which are the high-performance variant. They don't last as long but they cost less than the SK20s too.

I'm a bit concerned as to whether something wasn't done correctly in the cam belt change which could be causing some sort of problems.

what ones have you got in your car??as said they might be correct and might be a deeper problem ie incorrect fitting of something during the timing belt change as stevie said.

this problem started happening before timing belt was changed but not as often as it does now. i have changed the camshaft position sensor and the crankshaft position sensor too.

maybe its a faulty spark plug and its getting worse by time.

Are you sure that the earlier problems weren't genuine coil pack failures though ? Maybe you really did need to swap the coil packs/plugs earlier, but now you've got another different problem, albeit one with similar symptoms ? Did you get codes read before ?

Was the car cutting out completely before or just not working on all cylinders ? When it cuts out at the moment, it just dies completely, yes ?

when i had coil pack problems it was actually misfiring. when i do drive it now it doesnt misfire. it just cuts out completely n when i got it read it gave codes P1300 (Igniter Circuit Malfunction no.1) and P1310 (Igniter Circuit Malfunction no.3).

have you had the plugs out yet??

yeh had em out a couple of days ago n they looked fine 2 me. bit ov carbon on em n just cleaned em with a wire brush.

what was the number on them?are they the right plugs?are they iridium????
lookin fine is different from being the right ones for the car. and if you've cleaned the plugs with a wire brush and they are iridium you have just broke them you never clean those plugs that way as you take the iridium contact off the end!!!!!!

OOPS lol i will put sum new spark plugs in tomorrow n let u know of the outcome.

hope it all goes good. good luck

ok, so like I said, you might have two completely different problems that you're looking at as if they're the same. You must have a different problem now if it's not misfiring but cutting out.

But if the cutting out problem was happening before you cleaned them, that can't be the source of the problem.

Was there any cutting out (forget the misfiring) before you had the cam belt change ? I'm still suspicious something is wrong with the cam belt change.

Or did the cutting out problem start with the plug change ?

ok...changed the spark plugs and no luck same problem happenin. before the cambelt change it cut out once and went back 2 normal after that n didnt kick in til 5 months later, which is now.

have you try'd cleaning the throttle body?

yeh the throttle body got cleaned 3 days ago...i dunno what is causing this problem...but its defo causing me to pull out my hair!

have you checked the crank pully's tight?

No havent checked that, will check tomorow n update you on whats happening! anything else u reckon i should check?

Is the engine check light currently on ? It would be useful if you had an OBDII reader and you could check what is happening each time it cuts out. e.g. is it always producing the same codes when it cuts out and turning on the engine check light ? Then you can reset the light and see what happens next time.

I'm not suprised that changing the plugs didn't help, given they'd be recently changed anyway.

Cutting out could be for lots of reasons, but I'm wondering if the codes are misleading and whether they do or do not happen each time ?

ok, i got another code come up on the OBDII. cant remember what it is but its something like Mass Air Flow or what not!

I guarentee 100% its not the Mass air FLOW sensor.

Really you need the exact code to help diagnose. If its the Mass air pressure sensor then check the wiring and check the pipes down the side of the throttle body are tight.

I'm guessing you've got either P0105 or P0106 but as Stav said, we really need the exact details to help figure out what's happening.

It would be useful to get a better sequence of events too, I'm finding this all a bit confusing. e.g. were there no codes/engine light, then you drove it, now the engine check light has come on and you've got just this one code ? Or are there others too ?

weird. need thhe exact code to see what is going wrong and where its goring wrong.

Any more info/progress ?

???

sorry abou the late reply. ive been doin some more research into this and now people are sayin to me that it could be the MAF sensor??
