Having problems with your 1991 Chevrolet S-10 Blazer ?
My 1996 v6 chevy truck engine runs good at idle but in drive it has poor acceleration. In idle I can maintain 2500 RPM but in drive it does go to 2500 but the truck acts like it has resistance. I was told it could be a pluged catylatic converter. When on the HWY I notice a loss of power when I climb a mild hill. Is it a transmission problem?
Sounds like a catalytic converter - runs good but lacks power - the back pressure keeps the engine from being able to accelerate under load - good luck :O)
