1996 Camaro 3.8 A4

The problem is when I rev up the engine it will not go higher then about 2500 RPM, its starts to bog out and wants to stall and bounces between 1900 and 2500 or so RPMs in park, kind of like a rev limiter.

I went ahead and did the plugs and wires and routed them perfect and chainged the air filter. It did have 2 burned wires. Then I cleared the codes out and it will idle good, but still the same thing, it cranks for quite awhile then starts but will not rev up but its not kicking any codes back now.

I tried a test drive and its surging, will only do about 15 mph then its like it dies for a second and revs back up and does it again. If you stomp down on it all the way it will set off the mill with a p0300 code but when I clear it and do it again it wont set it off unless I try to stomp on the gas.

My mt2500 is showing 0 misses at all 6 cylinders, but when I get the mil to come on like i said, it shows total misses of about 15, but still doesnt show any at particular cylinders.

Gas cap is good and fuel pressure is aprox 45 lbs at idle.

Any ideas would be appreciated, im about out. Possable the cats plugged? Is there a common problem that exhibits these symptoms?

Thx

 

I put a fuel presssure guage on it today, with the key on and the car not running I hear the pump prime up, it goes to 45 lbs but as soon as the pump kicks off it drops to nothing.

With the car idling it stays at about 45 lbs and when I try to rev it up its around 45-50, but as soon I shut the car down pressure drops to 0.

Does this sound like a broken return line or foot valve in the pump?

I hate to change out the pump and have that not be the problem.

 

Could it possibly be a problem with the ignition coils?

 

Got the fuel pump out, there is 3 hoses that are inside the tank.

1 is a black hose that that runs out of the tank and hooks to the lines that go to the front of the car and hooks directly to the brown reservoir on the pump.

1 comes out of the reservoir and is open inside the gas tank.

1 is a brown coily type hose that hooks to what looks like the actual pump motor inside the revervoir and runs out of the tank up to the front of the car.

The brown hose has a pin size hole from rubbing the metal assembly that raises the pump up and down in the tank.

Im hoping that is where my pressure loss is coming from.

I figgered id post up what I found for reference if anyone else has something similer come up.
