    Help needed...What should I do next?

    today I spent another few hours just piddling on this thing, I cleared codes, figured I would start unplugging sensors to see what made a difference. After unplugging mass air flow, it runs 90% better. No Tps codes set for the first time, trans shifts normal and actually accels great. Thought I...

    I have them, but understanding them is my problem. I have had the gm guys at my work look at it several times, they are stumped as well. Their guess is another sensor is causing the issue, something that does not require a 5 volt reference
