mine did the same thing - i left it for a month and the engine light came on tuesday! It was due to ccylindr fisfiring and I had o replace 3 coils at a cost of £300. I'd advise to check the coils and sprak plugs and have it services others have mentioned.

Good question! I had AA dagonise the error and they said 3 cylinders where misfiring and that's what the garage said too! There was also an error code which said "random cylinder misfire detected"! Its only don 37k miles and was service by lexus @ 30k so not very happy. They just quoted me £360 for an early £40k service and they won't even change the plugs! Did they tell you which packs were missfiring ? also did they switch them around with the working ones to see if it really is the coil packs ?...... very easy thing for them to do! Thanks all. They just plugged the comp into the car, read the error codes and replaced the parts! Your comments were most helpful. Got the car ack today having spent £300 for 3 coils :tsktsk: Car runs fine and I finally have a bit of acceleration, however, when idling, the revs still go down slightly and they go up when i turn the sterring wheel in eitherdirection before settling down below 1000 revs! There is asolutely o shake as before - Is this normal?

cheers mate. Apparantly 3 coils need replacing so car shoul be ready tomorrow. Shoul I ask them to replace the spark plugs while they are at it - perhaps a new set of IK20 or IK22? the car is n IS200 sport with no modifications, which woul suit better the ik2 or the ik22?

Hi Chris Cheers for sheding some light on the issue. I took it ino a garage and booked it in for tomorrow. £90 each for a coil pack -that's exortion! For future reference you can buy them of eBay. Will this resolve the problm with the car shaking/juttering when in idle mode as if it was to cut off? Regards, Alex

Fluffy - we have not all got are fingers glued to the keyboard as some of us half a life too! Maybe you should start telling people what to do at "speechers Corner" in Hyde Park every Saturday? thnk it'll suit your style

Hi Guys I've got a 2002 IS Sport which has done 37k miles! Last night took a Type -R on and as i pushed down the accelerator in 3rd gear the engine managment light started to flash! I have rest the ECU and light went of but is back on again - its keeps flashing, then lits up, goes off and same again! AA came and diogonised that the cylinders are apparently missfiring! Any ideas, clues, solutions or suggstin would bemost welcome. Also the car jutters when idling at traffic lights and kind off shakes a bit, as if its going to go off but it doesn't. Thirdly, sorry for the daft question, but what is a "piggyback ECU" and who are TTE? Thanks
