1993 Pontiac Bonneville SE 3800 N/sc
If my car sits for a while it starts up and operates great for about 5 min. Then, it will chug under load and have irratic rpm. It almost feels like its trying to grab a gear but it isnt just feels like that. When I slam on the gas from a dead stop I get *chug chug chug chug vrooom chug chug*. My coil packs tested good, brand new tps, fairly new plugs and wires,new o2sensor. Whats the deal? Need Ideas Im out of em.
