'88 B2 2.9 BIG problem

[nate12346]

Ok i have been looking through the forums and have been seeing things close to mine but in different situations so I will post my own lol. Ok I was driving around Garden of the Gods Colorado and some highschool chick gets right on my bumper so i nail it in second gear from 1500 to about 5,000 RPM then out of nowhere It back fires and stalls but I kept my truck in gear to pop start it. It started and ran fine at idle till about 2000 Rpm and then it would backfire and act like it wanted to stall but once it reached below 2000 it would keep running fine....PLEASE I NEED YOUR HELP GUYS lol Im suppose to go camping this weekend haha. I read somthing about high throtle and high rpm might me the catalitic converter?????
Thank You guys/girls!!

well... i had a similar problem but it took me forever to figure it out but it was when i was at about 1k-3k rpm and it turned out to be my map sensor but his could be any number of sensor problems

Should I just run a Computer Diagnostic check? like OBD codes? But if there was a problem with a sensor, wouldn't the check engine light go on? I guess I will stop by Checkers tonight and run the codes to see if anything comes up.

if the check engine light isnt on, its probably not going to give you anything. these old OBD1 systems dont tell you much...

I had the Hall sensor go out in the distributor of my '88. Would just quit running, I'd shut it down, Start and would run for a bit, then it would die again. Didn't trigger any error codes or Check Engine light. PITA to diagnose
