Engine Mechanical problem
1991 Pontiac Firebird V8 Two Wheel Drive Manual 250000 miles
ok I was driving it today and it just dropped off to 1000 rpm wouldnt gain speed just kept losing it now when I start it I can get it up past 2000 rpm once and a while but 9 times outa 10 it just dies if you touch the gas its acting like its out of fuel but it has plenty we are thinking that the fuel pressure regulator may be shot and thats whats cousing the problem but not sure any other ideas or does this sound right
now we have replaced the fuel pump tested the map sensor tps and today we pulled off the egr valve one of the ports was plugged with carbon so we cleaned it and put it back on could this be my problem or should I keep digging before I put it together again
have the same problem?
