Power problem
Runs fine at idle and nothing rattling around in the converters and exhaust doesn't seem to be restricted.
Here is everything I have replaced recently: new plugs, plug wires I tested and were good under 8K resistance, took out plugs and tested coil packs all six plugs gave a arc packs seem to be fine,new fuel filter, fuel pressure regulator, fuel pressure at fuel rail 40-50 psi, new throttle body position senor, B&M shift kit in tranny, torque converter, front and rear seals in tranny, motor re-built professionaly 25,000 ago. Just had pressure testing done and bleed down test all looked good. Several diagnosics done only thing showing up is knock sensor not detected and low pressure in map sensor. Hooked up vaccum line to map sensor and engine light comes on. Took back off and enige light goes off. I give up any advice would sure be appreciated. Thanks 94sc
