Re: ZX2 jerks/naggs
I had the VCT die on my ZX2. This case doesn't sound like the VCT though because when mine went the idle was extremely erratic and the engine would even stall itself. It was occasionally impossible to start. If you unplug the cam sensor and it goes away then its the VCT. The check engine light will come on if the VCT dies, however it only gave me a cam sensor circuit malfunction code, even though there is a VCT advance/retard code in the PCM.

Re: ZX2 jerks/naggs
Mine also had the jerk/nag but my valve timing was off. I can only describe the symptom as the car would flip back and forth from full horsepower to minus 5 horsepower. Back and forth every 1/2 second. It almost felt like a misfire. However mine only did it in 4th and 5th gear when crusing and reaching a hill. It was worse in 4th gear. I reset the valve timing and replaced that friction bolt on the intake spocket because I figured over time it was slipping and that was why the timing was off in the first place. I never messed with the timing before then and I bought the car brand new. Unless they messed up at the factory? Hope this helps, or at least its one more thing you can eliminate.
I have a 98 Zx2 with 95,000 miles |

Re: ZX2 jerks/naggs
that doesnt mean it is/it not VCT, you can unplug the VCT and the car will run just fine.

Re: ZX2 jerks/naggs
Altec, I'm assuming your saying it could be off not dead? Stop me if I'm wrong but wouldn't the PCM pick up on the variance in position and report a code? Or is it not that fine tuned? In other words it would have to be way way off time to trip the code.

it would throw a code, but it could be many factors other then VCT, my friend had a bad idle/stall that when you unplugged the VCT it helped a little. It was crankwalk, so it still just got worse.
