Had the car started for the first time this year... changed plugs and wires... reset iac and tps cleaned a few things and that was it... started up... ran a little rough at first until it warmed up then it ran fine... revs good and smooth... I decided to open the dump and it started sounding like it's missing... revs slow and choppy... can't figure out what I did by opening the dump... never happened before... any help appreciated
