It only happens after 20 minutes driving

Where would that be are they easy to change when I took it to my local lexus dealer it came up lean bank misfire 123

If any body needs second hand coils I have six for sale they were all working when I changed mine you can have all six of individually

Done the coils plugs injectors noticed the other night the cat was glowing spoke to a friend who's a mechanic and he said that one of the cats could be breaking down when it gets hot

Has any one experienced a misfire on their is200 due to the cat blocking up or breaking down when hot

Has anybody experienced a misfire on thier 1is200 due to the cat braking down or being blocked

Well got the car back from the lexus dealer with a number of codes they still can't pin point the fault so here was what the diagnostic report said

P0171 system to lean (AF lean malfunction bank 1 )

P0300 random/multiple cylinder misfire detected

P0301 cylinder 1 misfire detected

P0302 cylinder 2 misfire detected

P0303 cylinder 3 misfire detected

Can anybody shed a light on this now they are saying it needs further investigation

Did you get a misfire after twenty minutes

I could post fault coed if any one could help

That's a long list to go through I will ring the local lexus dealer in the morning to se how much it will cost to put on their machine will keep you all posted any more ideas keep them coming many thanks to all who have posted thank you muchly ... Ryan

That's a good price there is a lexus dealer a couple of miles away. Yes you can feel the misfire when your driving and when it's just ticking over but it does not stall

I think that will be my next move take it to a lexus dealer like you I'm at my wits end I just want it back now I'm having the ecu tested by a specialist but is it worth doing that if I'm going to take it to a lexus dealer

Yes I drive for 20 minutes or so and it's fine then you can feel the misfire kick in when I'm at the lights or just on tick over the revs drop to about 750 and its very lumpy it still drives but a loss of power is noticeable.

Not sure what machine it gets plugged into I know when the rac plugged it in its says the same thing.i have had the injectors checked it starts up with a misfire on cylinder 1 the its goes 123 the car still drives when the misfire happens.

Forgot to say the engine management light flashes on as well

Hi all I posted about a month ago that my is200 had a miss fire since then I have had new coil packs new iridium plugs still got a misfire. It's fine for the first twenty minutes then when it gets warm it starts miss firing again could it be the engine ecu or some thing else does anybody have any ideas. It's a 2001 plate done about 74000 miles manual.When it's plugged in to the machine it only comes up with lean bank misfire no actual fault codes. I'm now at a loose end with the car totally gutted as it has always run beautifully please please help.
