Re: Rough running
Well this thread is going to flipped upside down.
I just recently purchased a NOS 1991 PROM. I wanted to try out a stock tune on my car and see how it reacted. It is very interesting how the car reacted. No stumble at all under the exact same conditions as before, and I noticed that the BLM/INT's were more consistent side to side. With my Haibeck tune the INT's get way off from side to side, and during a decel drops to a really low number. The stock tune never got below 115 on INT or BLM's. Very interesting. It appears the O2 sensors worked better as well. The car did backfire quite a bit during deceleration.
I will attach the datalog. This points me to a tuning issue for my Decel, tip in, stumble issue.
To look at the datalog you will need to change from .pdf to .xdl file extension. Could someone review and compare?
