Re: 1991 Z28 Fuel line/pump issues??
I also have a 1991 5.0L. It will run fine for a while, miles even. And then will try to stall. When I give it gas it will rev up and stay there. It will be around 1000RPM in drive and 1500 in idle. I cleaned the Throttle body (it wasn't that dirty) and it ran fine for a couple mile trip. But when I got it back into the garage and put it into neutral it spiked to 2500 RPM. I applied the gas and it only went down to 2000 RPM in neutral so I shut it off.
I have been looking at the forums. And there are a lot of talk about checking the throttle body, TPS, IAC, fuel filter, and fuel pump.
Since cleaning the throttle body was the easiest, I tried that first. I am thinking of attacking the fuel filter next since I am the original owner and it was never changed.
What do you guys think?
