Hello my friends I have an update, today I replaced a few sensor, did 2 that know are emission sensors just can't remember what theyre called one is on the passenger side of the engine and the other is at the back of the back of the engine, I replaced the TPS, and an oil sensor I knew that needed to be replaced, and also another sensor thats on top of the very top of the intake, can't remember the name of that one either. Removed cat converters and started the engine, I had No idea it was going to be that loud. It died on me about 3 times and after that it started to work normal, idle at about 700rpms and the rpms did not drop like it used to when I stepped on the gas, it seems to me like its reviving fine. Took it out for a test drive and runs fine at normal calm drivng, but its missing power when i floorit, did not die on me when I was driving it even when I stepped hard on the gas or after the test drive, but it lacks power when driven hard. Im thinking about letting it sit overnight check it again and replacing crankshaft positioning sensor tomorrow, any advice about the lack of power, could it be because of missing cats?

 

find a good injector shop in your area and have your injectors cleaned and flow tested. doesnt cost much so long as you take em out and send/take them in.

 

Ok update time, got new cat converter installed and replaced fuel pump just by hunch, seems like the big issue was the fuel pump, it was working before I pulled the fuel pump, pulled It out and stopped working. So the car starts fine, idle fine at about 700rpms and revs up fine. doesn't feel like it wants to die on me when driving, but does have a new issue, it shakes a little when it is being driven when I'm accelerating, if I'm pushing the gas pedal in normal driving it shakes. But to me it feels fine when I when I step hard on the pedal only does it when its accelerating for normal driving. Here's what I did with the fuel pump, I couldn't afford a new so I got a used one from the junk yard, could not find a camaro( very hard to find one at a junk yard). So I pulled the fuel pump out of a 92 silverado 2500. Could that be the problem?

 

where is the vibration coming from. seat of pants, gas peddle, steering wheel, shifter, feet or floorboards?

 

OK, just went for about a 30 minute drive to try and figure out where the vibration is coming from, I gotta say I didn't really feel it, I did add a fuel injector cleaner yesterday What is still doing that I forgot to mention is that as I'm accelerating it pulls back or forward constantly. If I had a boble head on my dash it would be going crazy.

 

like a surge or a jump?

 

Yes I'd say more like a surge maybe, I'd imagine a jump would be kinda hard and my car doesn't really do it hard I had a passenger that couldn't really tell if the car was pulling or no but as the driver you can definitely tell. Passenger was a girl tho .

 

it may be that the injector cleaner will work it out. also could be the fuel pump or filter. did you get it scanned for codes?

I have not had it scanned again, and I replaced the filter about a week ago, do you think I should look for the original fuel pump or if the one I got from the silverado 2500 is in good working condition, will it it work just like an original pump .?

 

test the fuel pressure and see what its doing.
