neednotherwagon

not my thread but thanks everyone this is why i dig the USMB! people read and post timely answers/tips if not provide a direction in which to go things i learned: 4eat's are stupider than i realized (well the TC at least) i NEVER realized the first RPM line was 500 and NO ONE ANYWHERE has corrected me on this *facepalm*

98 obs 2.2 4eat w/ 125k miles Mods - CAI with K&N cone air filter & DIY grounding kit I too have a rough idle same as OP (vehicle comes to a stop..runs smooth when sitting in P and N) Have - cleaned MAF, checked for vacuum leaks, cleaned PCV and adjusted idle (a while back haven't set back to oem yet) Haven't changed plugs/wires or cleaned my iacv yet (need ngk platinum but recommendations on wires from autozone maybe?) I pulled 2 IACV's from the local pick a part and they seem to move smooth after cleaning. will attempt installing one and cross fingers when i have time noticed today i have a yeasty buildup in the PCV hose and other intake hoses and this worries me. installed my hoodvent cover plates in case it rains and was curious if seafoam would help to extract any additional moisture from my intake if there?
