Well when I first got her she was missing just a little bit and I though oh just needs plugs and wires and a new cap and rotor but Ive done the plugs and wires and now she is starting to die and still misses, I will stop at a light and she will idle like hell the RPMs would be all over the place then I unpluged the MAF and now she will idle ok but die sudenly so I have been driving with both feet one on the gas and one on the brake to keep the RPMS at 700 rpms at a light and now she is starting to die around sharp turns because of the RPM drop and when Im trying to back out of a parking space slowly, she seams to shudder or miss now at about 30 mph. Is this all just a bad MAF??? Oh and when the MAF was pluged in she would be really slow from a start and then when I would hit 2000 rpm she would spin the wheels like a bat out of hell if I did not let off the gas. Any Ideas on this would be great its really getting to me and I can't afford to go out and buy the wrong part to try and fix this. Oh and this might be a long shot but does this sound like a fuel pump that is going bad as well?

 

don't know if this helps but it probabbly has to deal with the feul delivery system of your car , if it has a carb which i doubt you might wanna check the idle screw, and if not that might want to check float level.

but Also might want to look to make sure you don't have a vacum leak.

 

I didn't see any vacum leaks and no I don't have a carb its an 86 trans am TPI I will look for leaks tomorrow again though.

 

What's your fuel pressure at idle? This may be a long shot, but did you have the battery disconnected recently? When's the last time your fuel filter was changed?

 

The battery was disconnected when I changed the plugs and wires and I just changed the filter unless its gotten cloged again. And I don't have a guage to read the fuel pressure.

 

a possibility might be the pump might not be pumping up to standards. just a suggestion.

 

Thats what I was thinking, any idea how to check?

 

Check to see if u might have knocked a line loose while you were in there. I knocked a line loose that went to the charcoal canister when I was doing the o2 sensor and it went to hell in a handbasket. I hooked it back up when I noticed it and my car is fine again.

 

Going back to the battery. Try resetting your ECM and see if that helps. (loosen the neg. battery cable, let it sit for a few minutes, then reconnect. you may have to do that one or two times).
If your ECM needs reset, you could have the symptoms you are describing.

To see if your pump is working properly, get a fuel pressure gauge and put it on the valve on the fuel rail and see what kind of PSI you have.
