Thread: Reluctors, programming and all sorts of fun

Being on vacation I have barely found the highway.

No one tell Maffy, but it's time for me to actually diagnose the car. The hiccups are still present and as bad as ever. My thoughts are TPS/MAF at this point.

Kinda feeling like I'm chatting with myself. Which is cool, I'm talkative and most probably don't have much more to suggest than I'm already trying.

Tonight. Scanned the car. TPS and MAF are perfect when the hiccups are recorded. No signs of dropout or problems. TPS went 0-100 nice and slow w/o glitch or issue. I am thinking that if either were an issue, it should show. Anyone seen one be bad w/o showing on a scan?

When I initially got the car, I had to pass emissions a half hour after connecting the battery. So a few codes were told to be quiet. Figured maybe that was causing a problem (although it was fine for 6 months prior). Flashed to stock tune. No change

The trans really wasn't showing any gear change on the scans, which changed my thinking to .... pcm, crank sensor. Programmed up a spare pcm and swapped it in. No change.

Ok, I'm not crawling under the car tonight. Because it's mine, that's the only reason. I tried a crank learn aka case. No change

Tomorrow I'm heading in after a crank sensor and or ICM.

Ruled out:
Transmission
PCM
Crank learn

Remaining to be ruled out
MAF
TPS
Crank sensor
ICM
Wiring

If anyone has suggestions...I'm listening.

Thanks for the ideas bud. I covered the pcm already. Funny little tidbit. I pulled the pcm out of the airbox, noted the service ID number and a sticker that said Regal PCM. Thought..maybe it's a reman. Then looked at the programmed one and ....it was the same service number and had the same sticker that said Regal PCM.

Crank sensor tonight...maybe a maf, but there's just no fluctuation in it.
