Hello friends this is borninabarn.Im logged in to this forum at the the shop.I have been letting our tech here use this site to figure out this tahoe.It is just a brainteaser.He did put a new gm fuel pressure regulator on this thing.Seems to keep running the same.Throttle body all cleaned out(was pretty gunky but still is acting up)something is telling the computor to cut the fuel down when it hits 125 runs fine for a few minutes then down hill from there.Could the exaust being plugged cause this thing to react like it is?Will try that next i guess?no offense to any of you techs out there i use this site alot at work to help me fix some of these odd ball problems!Thanks Kurt
