Hi all, I'm new to this forum, but it has a lot of knowledgable users.
Most the info here is over my head, so I have a steep learning curve.
Hope it is OK to ask for help in this opening e-mail.
On Tuner Pro RT ver 5 (unregistered), how can I add Ignition timing advance and EGR state to the acquisition list so I can monitor those during driving? Also, how can I identify the ECM as site suggest my truck has 3-4 different ECMs? Tuner Pro RT shows PROM ID of 9025. I am using A179.ADX to acquire data, and can save log files. I did not load bin and xdf as I did not want to attempt tuning.
My goal is to fix my 1994 K1500, 4x4, TBI, 5.7L, manual 5 speed trans, which starts well but begins to run poorly after a couple of minutes. Any slight pressure on the accelerator causes it to buck and miss. Not trouble codes are set. If I let it set for 30 mins, it starts and runs fine no problems. Or if I keep babying it for an hour of driving, it slowly gets better. It only acts up the first start and run of the day.
I was hoping to use troubleshooting, and not shot-gunning the problem by replacing parts until is ran better. Maybe it is silly pride as I've spent more time thinking about it than parts would be worth.
