So my truck runs so perfect when it first starts up but after about 15 mins it doesn’t want to accelerate and vilolently shakes when trying to accelerate. It has tiny backfires and dies if I push it for another 10 mins. I’ve replaced the fuel pump, injectors, plugs, wires and distributer cap. cleaned throttle body and map sensor. Idk what’s causing it, any ideas? In my head it has to be fuel, air, or exhaust related. 89’ 318 TBI btw.

Where is the O2 sensor in these and is there only 1?

Did you ever get a response on the torque converter clutch solenoid, code 37? I am getting the same code and the truck hesitates abruptly during acceleration. Wanted to check before posting to the group again.

Thanks

i havnt heard anything and I haven’t fixed the problem. I’m going to have to take it somewhere and see what is the deal.
