My Camaro is a newer one - 89'(Fuel Injected)
I rebuilt the heads in my camaro. Then I put it all back together, and it ran beautifully - but not for long. When I would step on the gas it would cut out and die, so I could only run it at low RPM's. It was dying because it was getting way too much fuel, I could smell the gas and it had the characteristics of a flooding engine, for it would delay for a second (and possibly die out)when I hit the gas. The problem progressed. I got to the point that it woulden't run. I did a diagnostic, and came up with a code 22, or, the Throtle Position Sensor. I got a new one, and I know that your supposed to set it by the amount of ohms coming out, but the book didin't get that detailed- it simply said to Line it up. So I installed it by thier means. It flooded even worse. It flooded so bad that it pushed gas beyond the compression ring and actually filled up the oil pan with gas. The problem seems so bad that it seems like more than the TPS, mabry injectors, I'm not sure. Perhaps some one has had the same problem and I'd apreciate your input.

Yeah, you need to test the fuel system with a good gauge.

Is it a 2.8?

It should hold 38-42 PSI.

Could be a bad fuel regulator. When they fail it could fill the engine with fuel in a hurry. Check the vacuum lines/throttle body for being full of gas.

lev,
You need to take the car to a shop and have them set the tps with a scanner and then reset the base idle, if it has been messed with. You have to have the correct tools to do this. Once this is done, you can see what other problems you might have.

Check the fuel pressure regulator. It may have a ruptured diaphram which will suck gas straight into the manifold.
