Stalling issues - Code 31 (Camshaft Position Sensor)

[We Gone]

All the items you listed are fairly easy to check.

I would start with IAC check and reset, TPS easy check with a meter, Map, fuel pressure issues easy just need a FP gauge.

Most if not all this stuff can be found in Dynomite's sticky

This may be a bit out there but what chip is in the car?

Also slow down and get the FSM.

I'm sorry if I feel a bit lost, I've pretty much only worked on rotary engines in the past.

There's no chip in the car, but that will probably be the first mod (after I fix ALL the problems, of course).

Do you think this manual is OK? Not sure if it has info on ZR-1s.

I'm actually searching hard on how to test the IAC. One thing at a time.

Thanks We_Gone for your help here and via PM!

That FSM should have what you need, Their is one more supplement for the LT5

Here are the book #s

ST-364-91 Service Manual covers L98 & LT5.
ST-364-91 EDM Electrical Diag, supplement.
ST-364-91SB Service updates.
ST364-1990/93-LT5-Supp.

When you get them read-read-read

I brought up the chip as GM had a few revisions to address idle issues they should be in the link on Mark's site

Do you think Dynomite's ALDL Code reader is a must to read codes quickly? It seems to be pretty awesome.

A very good tool to have, makes reading codes so much better than the paper clip!!!
