2002 VW Jetta 2.0 AZG - Significant Engine Vibration at Idle

Asked by Jan 27, 2017 at 08:12 PM about the 2002 Volkswagen Jetta GL Wagon

Question type: Maintenance & Repair

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
MAF?
