I hope you all can help. I am stumped.
85 toyota 4 runner.
Brand new 22re motor with mild cam for torque.
Replaced fuel filter and pump in tank.
Runs great when cold but when warm cuts out realy bad under throttle load. Replaced TPS. Have vacums hocked up and timming at 5 degrees when bypass set. Any help would be greatly appreciated. Thanks
I think coolant temperature sensors or 02 sensors and or the mass air flow sensors.

Well still no luck. Rats!
Replaced o2 sensor and coolant temp. Mass Air flow checked out fantastic. Thought that I might have intake leak when warm but tried wd40 around entire intake and no change in idol. Any ideas? Thanks again.

Has no cat on it or sensor. 85 had only sensor at y pipe on exhaust.

The last thing I can think about is the EGR valve systems?
