Replaced plugs, cap/rotor, engine coolant temperature sensor, speed sensor, timing belt/tensioner (double checked marks), fuel pressure regulator.No change.

Swapped, AMM, oxygen sensor, throttle/TPS with another 240, no change.

Cat raddles, removed test plug, no change.

Have driven in neighborhood, temp goes into red zone when trying to accelerate repeatedly.

Idle, somewhat high, at one time surging, but no longer.

Replaced fuel filter, jumpered fuel pumps at relay under dash, they work.

Previous to current condition, heater hose bursted, car got hot. Then car would not start. Replaced starter, ran fine for two days, then the above no accel condition occurs.

Completely stumpped, I have 4 of these cars (89,90,91,92), I thought I new something. Help, normally all of these cars are in use everyday. Thanks in advance.
