My 1992 chevy s10 4.3L TBI Blazer has been acting kinda funny lately. First off once i start up the truck it immediately revs up to about 1500rpm, and when im accelerating it will only max out at about 22-2500rpm. Second when i start the truck and let it run say to warm it up or something it will ultimately sputter then die, thus having to start it back up and feed it some gas. and Finally it has been alot noisier than usual even more so when accelerating kinda sounds like a semi truck or something. Any suggestions are appreciated thanks in advance. FYI fuel filter and a fuel line were recently replaced, and yes it is all connected properly. The Problems I have been experiencing seem worse in warmer weather. The truck seems to run fine in the cold. Any Ideas?
 
if the check engine light is on,
go to a mechanic and they'll tell you what it needs.
 
It's one of your senors ie; MAP Sensor or Oxygen Sensor. I would take it to the nearest auto parts place. And have them retrieve the codes, so you know exactly which one to change. Advance auto and Autozone where I live will retrieve the codes for free.
