Hey guys i just got my wiring harness back from tpi parts net and installed it. Car started right up but I have to keep on the gas to keep it running. The car accelrates VERY smoothly, better than it ever has. It has plenty of power now, especially after I installed my hooker 2055's. I do have a code 34, low Maf voltage/high vacuum??? The Maf sensor is newer, and all 3 relays on my firewall are brand new ac delco units I had tpi parts.net send me.

Here's my question, what would cause a HIGH vacuum at the Maf sensor, since I dont think this is a electrical problem, being the harness is reconditione, and the relay is new? Can a distributor that's going bad be the cause of this? And lastly, can a vacuum LEAK cause this, because my Crank Case Vent tubing is old and possibly leaking on my passanger side valve cover.

 

Oh and the TPS is set correctly, with .54 volts closed throttle, and 4.53 WOT.

 

IAC maybe?

 

It's brand new too, lol.
