Ok I got a 1999 2.4 Auto with about 120,xxx miles. Done the major tune up which included new:
AC Delco plugs, boots, coil wire, and coils (didnt change coil housing)
Fuel filter
Air filter
FP regulator
Front O2 sensor
New muffler
IAC
TPS
No vac leak found
No CEL (ever)

Car runs great when I 1st start her but the minute it warms up it turns into a damn vibrator. Now it only vibrates in forward gears, if I put it into park or reverse it goes away. Im thinking motor mounts but just curious before I start dropping money on guesses has anyone ever figured out this common issue with these 2.4's (clogged cat, convertor) ????
