Question about 1995 Chevrolet S-10 CA Edition
My s10 when i accelerate bogs down and backfires i have replaced the catalytic converter and transmission speed sensor
Possible cracked sparkplug insulator. Faulty plug wires. Both can cause a backfire. I would replace the plug wires if they seem worn, and check each plug thoroughly. Good Luck

Rob, it sounds like a throttle position switch to me. My 95 suburban with TBI had a similar problem and that fixed it. You may need a volt/ohm meter to rig it if you don't have a code reader that will monitor the values. I think the switch was about $25. Not sure if yours has a TBI or carburetor.

SOURCE: do I need a catalytic converter
Yes but there could be other causes. A sticky fuel injector, bad fuel pump etc. Other signs of a bad catalytic converter are a smelly sulphur exhaust, a very hot exhaust throwing heat from the middle of the car. Unless there's a lot of miles on your car, I'd be surprised if it were a bad Cat. Hope this answers your question. Best of luck.

Fuel filter, plugged exhaust (even though you replaced the Cat), low compression, low fuel pressure, valve timing, MAP Sensor? Seems like it's temperature related if you can go 15-20 to start with then only 3 after that...

The Catalytic Converter is one possibility, but not likely. If when the truck bogs down, and stalls out, this could be more related to a fuel pump issue. If on your truck the fuel pump is located inside of the fuel tank, then once the pump heats up, this would happen. Acting as though it's something electrical, but it's really not.
