[jturbo96]

3.4 motor from a 94 lumina z34 put into a 86 fiero se ive replaced the coils, plugs, wire, fuel pressure reg, o2 sensor and other stuff that shouldnt matter. the car has verry little power and revs very slow, everynow and then i can hear it popping alittle and i can just smell the gass like its running realy rich

[robertisaar]

MAF? is it throwing any codes? and i know there isn't a whole lot of room for exhaust, but is there a cat there?

[jturbo96]

dont know about the codes i never wired the obd port, the one in my car was missing when in got it, no cat my exhaust is just a y pipe comming from the stock mani to 2 mufflers to the tips

You need to wire the ALDL connector and take a look with a scan tool or laptop to see what is going on. It will be more expensive to start guessing and throwing parts at it. It might be as simple as miswired connector.

^X2, that will be the fastest/cheapest/easiest way to do it...

[jturbo96]

[robertisaar]

Maybe if the engine sat long enough, the injectors are sticking.

[ghrarhg]

What ECM/bin file are you using to run it?

[jturbo96]

i cleaned the injectors and sinister performance did my chip. not the damn thing barly runs and i cant get it to start. it use to run better than this

[robertisaar]

i would suggest staying with a board member's chips(ben included) since we know our engines better than anybody.... as far as it not running: do you need to give it a little bit of throttle to fire, then let off and it idles by itself? if so, thats somewhat normal after changing a chip. after a few start cycles, the ECM learns the correct position for the IAC and it should start fine. if not, SP should be getting a call from you, asking why they sold you something worse than stock...
