My car is a MPFI firebird.The RPMs started going up and down when I would let off of the gas right before a redlight or a stopsign or stopping at a line to smoke a stang!!anyway the check engine light came on.Trouble code #22.I then replaced the TPS sensor.I then noticed that the car began to skip.I then replaced the IAC valve.still no effect.I then crunk the car.It began idling very ruff.I cut the car off now it will not crank at all.Any info would be greatly apprciated.Thankx.

 

Brent,

First - Welcome aboard!

Second, if you post a topic and there are no replies, instead of posting a second topic, add a reply to the post with a line such as "TTT" (to the top) and the reply will cause the message to be moved to the top of the board (as ANY reply will do).

Finally, what year is your car? What modifications if any have you done?

I'm new at this web stuff.The car that I'm speaking of is a 91 pontiac firebird.IT has a stock V6,please dont laugh.It is MPFI.The mods that I have done are as follows... K&N Filter,ramair 2 hood,4th gen wing,5% tinted widows,dual exhaust,flowmaster muffler,shaved radio antenna,replaced door handles with a set of 97 pontiac grandam ones,custom t-top covers,interior was beige now it is all black,white face gauges,this page is not really big enough for all the stereo mods,but it does have a tv in it.You could almost eat off of the engine,I also shaved the gas filler door and moved it behind a custom hinged taillight.Well I hope that this info cleared up some things.What could be possibly wrong with this bird on fire?thanx.
