Over the last 3 or 4 weeks ive done a BUTT load of work on my car, and thought it was good to go, thats what I get for thinkin right? So me and a friend adjusted the timing yesterday and It drives home nice, so this morning I go out to crank it up and it takes 1 or 2 tries(been having this problem, thought it was the timing though), After I get it running, its a rough idle until it warms up, slight hesitation when I put it in reverse and drive, seems to surge now and then when im going down the road and its shifting at a higher RPM than it used too, Ive also noticed a slight exhausty smell, and when I try to go into passing gear, or when I drop it into second, I get a really loud rattling comeing from up under the car(checked around for something loose to no avail) I was talking to a friend and he said it sounded like my fuel to air ratio was bad, or maybe my pump was going? I dont know, im quite lost on what to do/check right now, as far as I can tell, its the fuel pump, IAC, injectors, EGR? in the fuel system? Heres a list of what ive replaced thus far.

Spark plugs, wires, rotor cap/button, O2 sensor, temp sending unit, fuel filter, O rings on the injectors, Manifold gaskets(had a torn one), MAF sensor and both relays.

Any help is greatly appreciated!!

 

Maybe check your fuel pressure? TPI should be around 45psi IIRC.

 

Yes, ill be doing that hopefully tomorrow, assuming I can find a guage, Also was digging around the site and found out how to check the injectors and the IAC, just feel like im shootin in the dark. Thanks!
