What's up guys i have a 95 impala ss and i have a LE2 top end cam package and at 125k i rebuild the bottom end. My car was dynotuned prior to the rebuild and ran great, after the rebuild I developed a idle issue, so i started playing with the throttle body and no luck. Then I did some researching and some were saying it may be the MAF, so i had one that I bought a while ago from a forum member switched it out along with the IAC sensor that TPS. I have new Plugs autolite platniums in new opti. I also have fairly new O2 sensors less than 15k or so new walbro fuel pump ect. I'm lost i was just wondering if I need to have my car dyno tuned again to line everything up again. Also seems to running a little rich also becaus i can kind of smeel gas as im idling in traffic but nothing major. I was considering what to check out before I went and had my car dyno tuned again. Thanks and the only thing replaced in the bottome end was the rings bearing ect, I also had the block honed and the machine shop. Can somebody help, Car seems to run fine other than the first start up and pulling off. I'm sorry for sooo long LOL Plust help thanks
