Hi all-
Wondering if anyone has any suggestions. My 87 2.8L has been experiencing extremely rough stutters through acceleration. When I really use the gas pedal, it chokes and sputters like its running out of gas, and it will stall when coming to a hard stop. Took it to the shop, and they replaced the MAF. Got it back, and same symtoms. So, I checked the codes and it came back with 33,34, and 45. Im guessing the 33,34 are why they replaced the MAF. They also replaced the fuel filter. They did not replace the O2 sensor.(BTW, car passed emmisions test in PA right after MAF replaced) I called the shop, let them no that the car still had the same symtoms, so Ill be giving it back to them tuesday.

Anyone have any thoughts or suggestions?? What else could it be? How should I deal w/ shop. I reset the codes, so ill need to try to get them back. A quick trip down the highway, hammering the gas didnt do the trick.
