I can't access any stored runs, I recorded each run and it says there are no stored runs which is also frustrating. My sensors seem to be showing accurate temperatures. I don't know anything about fuel settings or what they should be. Had it tuned by a pro and saved it to a file. I reloaded that to see if it would fix the problem but it didn't.

Ok well it looks like you'll require some assistance from someone with Accel experience. I'll assume speed density tune? If so what's your MAP sensor reading (possible vacuum connection or restriction in hose) maybe take a look at that since it's a big input for fuel strategy and you're saying IAT ECT sensors read normally. Is your TPS zeroed ? A quick check for the MAP is see if it reads same as BARO sensor (should be close with engine not running). Best bet in my opinion is to get to your logs and retrieve them your issue will almost certainly show up. Good luck. Joe

Bobby, have you looked at the fuel side of it? Regulator? Pressure seems to be where it's suppose to be? Even on the run?

I have good fuel pressure about 38-39 lbs and when I take vacuum away from regulator no fuel comes out. I think the injectors are just staying open too long and I'm trying to figure out why. Also, does anyone know about what number the Map sensor should be reading?

As i stated MAP should be same as BARO (assuming you have a BARO sensor) engine not running most MAP sensors read approx. 99-100 KPA. Engine running will vary quite a bit due to intake and cam design, I would expect around 45-65 KPA at idle decreasing as you rev engine to maybe 35-45 KPA. Off idle your vacuum will stabilize a bit and provide a better signal. WOT you'll likely see 90-100KPA essentially BARO pressure. Good luck. Joe BTW your baro reading may be higher or lower than I listed depending on your location ie in the mountains or at sea level.

Not quite.. I am wondering if my ECU is having internal issues. Could you check out my other thread with the screenshots and let me know what you think? Thanks for your help.
