1991 Chevrolet S10 Blazer Q&A
1991 Chevrolet S10 Blazer Question: Whats wrong with my truck?
I have a 1991 S10 Blazer 4x4, with a 4.3L V6.. it has 193000 miles on it, but it has been well kept up. It was running just fine until one day recently I was drving down the highway and it started jumping. Then a few days later the blazer, began popping and jumping very badly. It wouldnt stay started if I took my foot off the gas. Now it has a VERY rough idle, where the entire truck rattles and shakes..I cannot start it and move it, because just as soon as i take my foot off the gas, it begins to sputter then dies.In the middle of all this it also overheats, and smokes after running for ten minutes or so...Which it never did before the sputtering, and jumping,etc... I have had this vehicle for two months and it never did this until just a couple days ago.It was a strong running truck. I would really like to fix it because it is my only transportation. I have no idea what it could be. I know that it was given an oil change, but we have since had to have more oil put in it beca use the oil filter housing has a hairline crack in it which causes it to leak.. The only other problem I have is a faulty gasket on the transmission pan... But it was runnning great until all of this came about... - 4x4blazergirl

My truck will shift into park, drive, reverse, etc, but it gets stuck in 2nd gear when you try to drive down the road. You have to punch it to get it that far, we discovered that while trying to li...
