Wild suggestion: check that vacuum hose for the regulator over closely. I dunno if the gas could have dried out the rubber boots, and is leaking vacuum.

Ok well today just for fun i did a fuel pressure test and while the key was turned it was at about 42, and while running it was at a pretty steady 36-37 and a mechanic friend suggested testing the fuel pressure regulator by disconnecting the vacuum line while it was running and fuel pressure should increase by about 10 if the regulator is good and sure enough it did so now things are decent but i still wonder why sometimes it goes back to it's old ways....

I am thinking about the IAC motor on my car. It closes to restrict air flow when the engine is cold. If it were to fail to open, it would definitely cause some problems. I believe mine is vacuum operated, by a module behind the intake manifold. Check the hose for cracks, missing hose etc...

Ok well all my hoses etc. looked ok and i took out and cleaned out my spark plugs. All looked pretty good just a bit of carbon build up. I took it for a drive without touching it for a few days and it seemed all good although it did seem a lot weaker than it used to be... Someone suggested i may have a bad mafs... because of the symptoms i explained and becaue of the video i showed them. I also "tested" my mafs by unhooking a sensor to it while the car was running and there was absolutely no change whatsoever. Except for a check engine light. Other than that the car ran the same idled as usual etc. revved up the same as well. Someone told me that's a good way to see if it's good or bad they said that if it's good unhooking will cause a drastic change and if its bad well usually no change. I have no clue how accurate that is or what exactly it SHOULD do if i unhook the mafs while the car is running. It even started right up without that sensor hooked up.... I'm honestly still afraid to drive the car because of fear of getting stranded and or having to push the son of a bitch a few blocks again. I want to get everything sorted out with it.

here's a pic of what i unhooked its' the one that's not plugged in. I believe what it goes to is the mafs if it is not someone please slap me.... I didn't try unhooking the other sensor that's there as well but in a different spot. I honestly didn't even see that one until just now when i went out and got a pic but it's kinda late and the delta is kinda loud... *no cat plus a whole mess load of holes in the muffler..*

Thats definately the mass airflow sensor you unplugged. It is different than the maf on my car, and unplugging it should make the check engine light illuminate.

If it doesnt come on, you might have a burnt out check engine light, which would explain a lot. If that is the case, there are likely codes stored in there that would help you out, but you couldnt read them because the light burnt out.

The check engine light should come on for a few seconds at startup, so you can see it is working. Check that out. Might save you a lot of time.

WEll i do get a check engine light but that's it. The car still runs the same as usual....

Sadly I couldn't keep this car with all the problems it was giving me. I got it to the point where i drove it for a whole week with no problems, and then i sold it this evening. I'll hopefully be staying on the forums and will be trying to pick up a g-body cutlass over the summer so i'm not leaving the forums for good. Thanks a lot to everyone who helped me out with getting the car running again it's greatly appreciated.

no problems, sorry you had to let it go. Sometimes cars are more frustration than they're worth. You let the rims go with it?

The rims i had on it before were sold. I let it go on some wal-mart hubcaps that were laying around the garage, and i included the stock ones in the trunk as well. Right now i got myself a civic last night, and that thing is rusty but damn was the motor well serviced. It was a single owner since 1991 and they have maintenance records on the car since 1991. I just got some bondoing/fiberglassing to do and i'm gonna try and sell it this summer.

Have you considered the Catalytic Converter?

It might be possible that your exhaust is clogged. When your you car gets hot it could be burning the crap inside causing it to not expel properly.

We may never know, because, he has sold the car. Check a few posts above.

It was already (literately as well as figuratively) eliminated.
