JRW racing

TPS is not new. I am ready to put a damn carb on it or I might just convert this thing to propane

Ok I pulled the fuel pump and the screen was clean. I replaced the fuel filter the same time the pump was replaced about 2 months ago. I checked the CTS and MAT and both checked out good. My problem is money is really tight so I can't afford to just replace all the sensors :wall: right now so I need to narrow this problem down. I unplugged the O2 sensor and it drove fine until it got hot and then any throttle over half and I looked like a 16 year old kid learning to drive a stick :doh: Any ideas???

I unplugged the O2 sensor and still had the same issue. When it starts stumbling I push in the clutch and rev the motor and it will rev to about 3000 rpms and then loads up and backfires. My neighbor asked if I checked the temp switch :dunno: could that be the problem? By the way thanks for the welcome :cheers:

My truck starts and runs fine but after about 25 to 30 miles I can't give it more than half throttle without it bucking and stalling. I pulled the catalytic converter and found that the previous owner had gutted it. Now I am completely at a loss as to what could be causing this problem. Any ideas?
