2002 VW Jetta 2.0 AZG - Significant Engine Vibration at Idle
Very rough vibration at idle. Engine seems to idle smoothly at 800 rpm.
Replaced crank position sensor 6 months ago. Recently replaced
downstream O2 sensor, plugs, wires, coilpack. Replaced all motor mounts
12 months ago. Fuel pressure is good at 35-38 psi at idle. Used multiple
bottles of fuel system cleaner to date. Not sure what to do next: check
compression, replace injectors, replace fuel pressure regulator, replace
maybe fuel filter. sea foam is a great fuel system cleaner. check for kinked flexible fuel line.
