Thread: Lt1 Problems Please Read Kinda Long

Tweet

My truck had this problem that when i sustained rpms above 2500 or so it would bog up stutter even stall, or when i punch it around the same 2500-3500 mark it would do the same. After messing with the ignition to no end, i went through like 4 coils, i figured out that after it got real bad, my timeing chain was stretched and i guess the certain forces in that rpm range caused it to do funky ass things.

I"m no expert but what you describe seems to be almost the same thing, i dont have a lt1 but they both have timeing chains so you might wana check that.

Another interesting thing was that sometimes it would run perfect but you could literally turn it off go buy a soda and come back 45 seconds later, turn it on and it would barely go down the road.
