  • P1514 Code :o( Help Please!!!

    i know it has been posted by other people but I cant seem to understand this...so yesterday I get back to my glass shop from work and i start the car and let it idle til its at the idle temp as always, and my car starts stumbling really really bad, I tried to drive it and it stumbled around the lower rpms then jumps up normal...the check engine light came on and I had it tested at autozone and I get code # P1514 which is Airflow to TP Sensor Correlation High ... and I get the p0305 which is misfire on 5th cylinder, the misfire im sure its the coil pack but the TP sensor, does that just mean i need a new tps?? i mean it stumbles and bogs down badly! i know it has something to do with the maf or tps. 99 camaro 118K+ miles, new plugs and wires, plugs gapped correctly. good oil...plugs not fowled little rich smelling after problem happened....engine power light came on then went off cus i took maf out then put it back in. im stumped...hopefully its just the tps cause the maf is expensive

      Quoted from autozone.com for a 99 3.8l TPS:

      "Throttle Position Sensor for a
      1999 CHEVROLET CAMARO
      WELLS #TPS144 -$37.99"


      IMO, for $38 I'd replace it to see if anything changes. It's a HELL of alot cheaper than a new MAF!
      Also for your misfire, check your spark plug wires. They are known to melt & arc on the upper intake manifold and cause you to believe that a injector, spark plug, and coil pack went bad when it actually didn't. GM ran them spark plug wires way too close to the upper intake manifold, and excessive engine heat will begin to melt them and cause an arc in very little time.

            All thanks to the stupid EGR! They could've at least put some kind of spark plug wire loop on the cowl to hold the spark plugs from touching the UIM!
