Code 34 troubles/solutions

[gculver]

I seem to keep getting code 34(maf low/no signal) was doing this with old OE maf and rebuilt Cardone..seems to happen after startup when car idles down then begins to stumbles a little..like idle not high enough.. this is a fresh engine all sensors have been replaced. Other than the poor idle quality and SES code, runs good. Anyone with a similar issues in the past with suggestions. Thinking of trying another ECM that i have.

Try your spare.

I suspect the MAF.

I did the translator & LS1 - 3" easier to install than a 3.5 or 4, especially on a DD.

Tried a different ECM and old KB chip, same problem..tps is adjusted correctly, IAC counts seem to be good..Time to look at another maf and wiring ??..driving me nuts.. Any ideas.

Update...Open ground circuit in MAF sensor harness..Why now, I inspected each harness and re-wrapped them all during restoration ..Just goes to show you, you can't dodge all the bullets!:biggrin:
