Need Help

Need a bit of advice ive almost got this thing all fixed up. So heres the deal..... got a 1988 base coupe camaro with a 2.8l v6 the problem im having iswhen i start the car cold it idles a little high and when i press the gas it bogs down and dies until it get warmed up then it runs pretty nice except if i really step on it then it hesitates and i get a backfire at the intake. any suggestions. recent repairs include a new MAF sensor, new TPS, plugs, wires, distributor cap and rotor. Im also getting a code 22 which i dont understand as the TPS is new. any suggestions?

Check for a small vacuum leak. If the TPS is adjustable, make sure it's adjusted to about .55VDC between the blue and black wires.

Re: Need Help

Have you done a tune up yet?

Just because the sensor is new, doesn't mean that the wiring is good.

To maverick and six shooter- im pretty sure i dont have a vacuum leak the only way i know to check for that is to spray a little ether over them and see if the engine revs and the lines look good. as far as the tps i cant seem to get a voltage reading off of it i think the wiring may be bad how can i check this? start running wires? i dont even know where those wires end. oh and i forgot to mention i did put a new computer in this.
