My car: '87 Camaro 2,8L MPFI. I finished scantool lately and get datastream from it. I've converted it to the Excel table. Problem is, that my car stalls sometimes in traffic. Maybe can someone check my data table and give me some advice, what may be wrong with my engine or/and sensors. I can't find anything

Data:
http://my.tele2.ee/camaro/aldl.xls

At this stream, car stalls in the row 52.

At a quick glance, your BLMs appear quite high (148s) indicating a lean condition and your IAC step counts are getting quite low.

My first suggestion would be to increase the mixture.

 

How? Do you mean PROM editing? All my car is stock, including prom, so it must work. I've noticed too, that IAC is quite low, but what may cause this? I'm out of ideas...

 

Have you check fuel pressure? Weak pump or restricted fuel filter maybe.

Fuel pressure is OK, 35psi@idle. So you think, that with that data is all OK? All sensors and ECM functions are OK?

I've checked other datastreams too and noticed, that every time I take my foot out of gas, BLM goes high (150-160). And if i stop the car, it causes sometimes (quite often) stalling the engine. What may cause rising BLM and why ECM does'nt try to compensate that? What can I do, to improve situation? Why IAC closes too much, because of high BLM?
