Have a 2000 2.0. Sat for awhile. But i did some work on it and reinstalled the alternator, all of the air box from the MAF up to thottle body After cleaning it all. It ran great after i put a hot battery on it. Ran beautifully, then all the sudden it started a miss at idle and when i take off it spudders when i accelerate. If i back ofF or clutch in a little, it will clear up. And my secondary air pump doesn't have the fatory hose on it but it does have a hose from it to the air box. What is causing the misfire and the hesitation.
