have 10 of 2004 suzuki forenza 4cyl 5 spd 82,000 miles. bought from friend - had what i thought was a every now an again skip. R&R plugs, wires, timing belt, water pump & oil pump. skip gradually got worse. had codes read - P0342. R&R cam & crank sensors - no fix. R&R coil pack - no fix. Swap ECM - no fix. Removed & inspected engie wireing harness - found no problems. found it only does it when at operating temp - CK light comes on then the engine has jerks so violently one would think it was comeing out of the car. unplug coolant temp sensor it doesnt do it. R&R sensor - no fix. ???? HELP! Could an O2S cause this.

I mainly work in the last half of the day, so that is when I do all of my responding.
