hello guys, i have a problem with my is200. when i start cold car it start to shake. After a few minutes starts flashing bulbs "engine and trc off" . faults: misfire cylinder1, cylinder 2 and 3, i thought its high voltage coils, so changed 1-4 ,2-5, 3-6 but nothing, same faults. so what's the problem? maybe u can help me
ps. a problem only when the engine is cold!
sorry for bad english

 

First off, welcome. The first things I would check are the Idle air control valve, throttle position sensor and the MAF

 

sorry this is completely unrelated but I am new to this forum and a little lost. Is there a thread where people post cars for sale?
again sorry for the interruption, just looking to buy an IS.
