90 SHO running poor

[oneqwicksho]

1990 SHO just recently did rod bearings and a front 60k (have to redo front seal small drip) and before the front 60k the car was running raged. now sometimes it runs like brand new and other times it pops through the intake and has no balls on highway. the things i know: i have oil in plug wells ( top 60k in 2 weeks), max fuel pressure is 32psi (pump is wining bad getting replaced next weekend) mass cleaned, iac brand new timing correct, no crank cancer, clearance correct on crank sensor, and codes KOEO 111, 14, 16, 17 KOER 52, 74, 77

any and all help appreciated

thanks mike

The KOER are all operator error - you didn't do the various things that you need to do at the right time in the test - turn steering wheel both ways, step on brake pedal, goose the throttle.

The KOEO results suggest the cam sensor is bad.

I would do the top 60k, change the cam sensor, reset the codes, and see how it runs then.
