Tonyrodz's Tahoe Build Thread

It's just running at idle?

Did you watch it? Did you hear the pop? Seemed to me that may be like the popping you were describing..?

Ahh, I didn't notice. I'll look again.

I do hear it now. Does sound familiar. I noticed mine through the exhaust, I don't think I hear it from under the hood.
Thx for the heads up. I just hope it doesn't hurt the motor in any way.

Maybe you can try with the hood open, and see if it’s similar..?

I will.

What makes the crank relearn necessary? I've never had to do one and have replaced several crank sensors/entirely different engines with different cranks lol.

Between the guy's motor and mine?

 

[Tonyrodz]

I'm all set.

Well, pitter patter, let’s get atter!

Gonna do it tomorrow--hopefully.

I took it for some local errands and local highway driving. It drives like shit. Still popping through the exhaust and it almost sounds like every once in awhile it backfires. Nothing loud--maybe like a misfire. It idles fine--still hear a popping coming from exhaust. No codes either.

Well that's not kosher.

Nope.

What do you have to lose by trying the crank sensor relearn? You have a Tech 2, correct?

I do. I'm willing to give it a shot.

If it needed a crank relearn would it show a code of some kind?

 

[pwtr02ss]

IMO, you need to get it tuned sooner rather than later. Try the crank re-learn or whatever but get it tuned. Also, have you put some octane boost or run enough premium through it to go out of low octane mode?

 

[randeez]

yea needs to be tuned...you can prob ride around and watch the fuel trims, they prob way off under acceleration

I haven't driven it. It has 89 in it now. Maybe I'll put some 91 in it.

Am I looking at lt or st? Should it be at 0 while accelerating?

 

[randeez]

ST, if its reading zero you are into power enrichment

you should be able to accelerate fairly moderately and not be in PE, if giving it any little amount of throttle puts you in PE mode, that needs to be backed off some
