Was stalling, chugging(like choking) checked fuel line, changed fuel filter and all spark plugs, was a little better, thought might be fuel pump, took to a shop, they only replaced voltage or fuel regulator, charged arm and leg, came back with check engine light on all the time, now stalls when driving, slowing, stopping and runs worse than before. afraid now to take it in for fuel pump fix as that was even more expensive..ready to scrap the car
Air filter?

Need to check for fault codes. Possibly a faulty sensor causing the fuel system to run rich or lean.

I just had the same problem. Replaced the fuel filter,still crappy idle and no acceleration. I replaced the fump pump along with the wiring harness and the fuel pump screen and my cars purrs like a kitten,has back to normal acceleration and idles better than before. Hope this is some sort of help to you. I did it myself. Total cost, a little over $120. Good luck. By the way, your fuel pump should be pushing out about 65 lbs of pressure. is it ???
