need a little help
need a little help alright so i finally got my car running. took it out tonight and its havin a wierd issue. itll be driving fine for a while and then all of a sudden i lose power and when i try to press the gas it tries to stall. pull over turn the car off and then back on and itll drive fine for a little while then do the same thing, its very random though.
my buddy told me he was kinda havin the same issues until he unplugged the front o2 sensors. i tried unplugging them and still have the issue.
my friend didnt really change much when he turned off my vats. he said he adjust for the injectors a little and that was about it. i still have all the egr and evap check engine codes.
oh motor is a 2001 5.3l
any help would be greatly appreciated.

I would run a scan on the computer and see if there are any codes set. I would also do a data log while driving under the conditions where the problem occurs. If your friend tuned the computer they should have the ability to do this.
i was thinking fuel pressure too eventhough it idles at 60psi. goin to look at a couple things today. maybe i can get my buddy down to my house to see if he can adjust things.

If the power loss is happening at the same speed or RPM check ALL of your sensor connections, and grounds, if all good check the tune. You really need to get it data logged if the problem persist. And drive it as little as possible until you get this resolved. Have you tried running it open w/o the cat.
alright caught my exhaust guy as he was about to go home and he was able to take the cat off. car runs great now with no issues.
last night when the car was runnign it felt like the TPI was still in it and now it feels like a 5.3l.
