    I Have A 95 v6 the motor was just rebuilt due to bad head gaskets everything was replaced but pistons and rods.The Car Runs Fine For About 2 Minutes and then it begins running really rough and stalls when the engine begins to warm up only happens at idle.its hesitates on acceleration untill i put the pedal on the floor then it runs like a scalded dog.i have had a mechanic put a snap on computer on it and the only codes i get are from the o2 sensors which are unhooked after removing the cats.so far it has the following new items: iac valve,tps sensor,temp coolant sensor,Temp Switch,K&n cold air intake,Spectra Radiator....this car is really puzzling me ive been on it for 3 months Maybe it is something small im missing...Any Help Would Be Awesome Thanks.

    Have you checked the timing? Ground wire from the battery? even fuel filter?
