Normal Idle Vibration
This is a noob question but I can't find an exact answer by searching the forums. I recently purchased an 06 ZX4 as a commuter vehicle and, eventually, for my son to drive. It's been a long time since I've owned 4 cyl vehicle and I'm not sure how much engine vibration at idle is normal.
I can feel a slight vibration in the steering wheel and some in the seat when idling without the A/C running. With the A/C running the engine actually seems to smooth out.
I've read on the forums to check for vacuum leaks, possible clean or replace the IAC and/or TPS. Before I do all that, just wondering if I should expect some vibration from the Duratec 2.0?
