Hey guys, a lot of you know i have my ep3 obviously, but i also own a 99 EX coupe with 151k on the clock that i daily. i just recently started having issues with it, couple of months ago the exhaust manifold cracked and the cat flange broke. so i just recently replaced both the manifold and cat with OEM peices, and now that problem is fixed, but a while back i also started having an idle issue. i would come to a stop and the car would idle about 1500rpms for 15 seconds or so then slowly fall to a 800rpm idle. well it progressively got worse, then it threw a code for idle air system and the car was very difficult to drive. bucked really bad and had a 2200rpm (more or less) limiter. So i pulled the iacv off to find the screen clogged to hell. so i cleaned it. all was good for a little. then it started again last night. got off the highway from a 25 miles 80mph cruise and it loped between 1900 and 1000 and after about 30 seconds found its idle. so i replaced the iacv last night with a used one from a freind and its doing the same thing! not loping, but holding at 1500rpms after a drive. anyone have a clue? i'd love to hear opinions. im thinking possible purge solenoid? i have NO CEL as of right now
