    misfire on is200 auto p0420 p0302

    the misfire is definately on the petrol too, so what can cause a misfire on petrol that would also cause it on lpg, what is used on both fuel systems ?? i assume the petrol injectors are not in use when on lpg as lpg injectors are used but i could be wrong?

    Not sure buddy, just the code coming up as p0420 which on google says something about the cat?

    Hi colin after swapping coils over to new ones the codes come back, the p0420 code is pending and the p0302, p0303 and p0305 are back which is making me feel like it could be the injectors as definately it isnt the plugs or coils. although now the car has a stuttering misfire, revs bounce between 500 and 750 every few seconds :( and the misfire gets worse on lpg but the misfire is still present on petrol so it isnt the lpg system.

    anyone?
  5. Hi guys have been getting misfire with engine light and trc light flashing, having changed spark plugs and also coil packs, makes lights vanish for few days, change coil packs around, error still comes back on same cylinder after a few days? P0302 CYLINDER NUMBER 2 p0420 which i believe is the cat (but which cat as they have pre cats too dont they?) symptoms, idle gets rough, exhaust has alot of gas coming up cat makes a rattling noise too on idle car starts juddering , loss of slight power engine lights flashing and if i dont remove code for more then few days then p0303 and p0305 which is cylinders 3 and 5 light up too but always p0302 and p0420 come up first. the car is also on lpg if that helps. i have read that when the cats are damaged or blocked it can cause misfire symptoms but want to know your views. what do you guys think this is being caused by?

    misfire on cylinder 2 p0302 , p0300

    thanks for your reply Colin. I would assume the same as changing coil packs, spark plugs, rocker cover gasket and spark plug gaskets hasn't changed a thing. I think its better to just change the whole rail and all 6 cylinders right? would buying them brand new be important or can i pick some up from a spare parts supplier until they are fully working?

    misfire on cylinder 2 p0302 , p0300

    no body can give me a input on this matter?
  8. Hi ive had a misfire on cylinder 2 for sometime now, starts on cylinder 2, then shows up on multiple cylinders as p0300. I have changed the coil packs, moved them around, still comes up as cylinder 2, had spark plugs changed, had rocker cover gasket and spark plug seals changed, still no didnt stop the misfire, Ive had the codes read again today, came up as cylinder 2. Question is if i have changed all the above and still didnt cure the misfire, then what else could it be that needs changing? also just to confirm which cylinder is number 2 on the lexus is200 in the uk? thanks

    oil soaked spark plugs is200 help

    thankyou for that buddy, i will give it a try but i have a feeling ill be giving it to the garage to do as im kind of nervous about taking the rocker apart lol also ive emailed that seller and he sent me a snapshot of the oe toyota part numbers for these spark plug seals which is 11193-70010, ive searched that on ebay and loads more came up for lexus is200 so it should be the correct part for my lexus is200 :)

    oil soaked spark plugs is200 help

    if there is a diy guide for this or a video i could follow it as i do have some mechanical experience, but without that i feel i might mess it up lol. so this is the correct part, its in bulgaria so need to make sure this is the one? http://www.ebay.co.uk/itm/GENUINE-TOYOTA-SPARK-PLUG-TUBE-SEAL-SETX6-LEXUS-IS200-IS250-GS300-RX300-RX400-/112445361069?hash=item1a2e440bad:g:5oAAAOSwN6JY9bDp thanks

    oil soaked spark plugs is200 help

    yeay, so basically what your saying is oil is leaking from the top, and the link you put up thats what i need to add to the lexus to stop leaking? also how hard or easy is it to it those seals, could i do it myself or is it a garage job?

    oil soaked spark plugs is200 help

    the car has been parked up on the drive for around a month now as im driving something else atm, but to answer your questions 1) all the spark plug is covered in oil from top to bottom (see pic although i must say its about 3 or 4 plugs out of the 6) 2) I didnt replace the seals you have put in link, i replaced rocker cover gasket which goes around the side of the head? does this mean i need to replace the seals which you have shown in link too? 3)I havent seen any nasty smoke coming out except when i changed the spark plugs and it smoked like hell for like 40 mins or so. 4)no sign of oil in coolant 5) The motor uses some more oil then usual, normally top up half a litre every 4 to 6 weeks. hope this helps
