88 grand prix 2.8 won't accelerate
I have an 88 grand prix with a 2.8. It starts and idles fine, but as soon as I start to open the trottle the engine stumbles and dies. It will restart and idle fine. I have had the MAP, MASS, TPS sensors replaced. Fuel filter and fuel pump replaced. Converter has been flow checked and is OK. Any help on which direction to head next woulb be appreciated.
