Codes and Limp Modes
OK.
My stock 91 vert (NA) must be jealous of all the time I am spending on the 3rd gen this weekend. When I drove her home Friday night she acted like an F1 Ferrari instead of a 14 year old car. Everything was perfect. I parked her in the usual spot. This morning (Sunday)I needed to get some stuff for the 94 3rd gen.
The 91 started fine but 1 mile down the road, the check engine light comes on and stays on (it had flickered many times since I owned her but never set a code). No the thing has no power past 15-20% throttle. Cruises fine at 45 mph but no acceleration or power.
Got her home and set up the code reader and got the following codes:
12 (TPS)
13(MAP)
17 (Feedback system)
20 (MOP sensor)
26 (I know, there is no code 26, except the 91 shows this as a problem, I rechecked it 3 times)
27 (MOP)
73 (Rear Secondary Inj)
Are these all bad or just showing bad because the engine is in "limp" mode. Any idea how all of these go to **** at once Or does someone know of a cascade effect of failures?
HELP!!!

Nurse I need 1300cc's NOW
you know what though. if the car is running like crap and all your feedback senors are messup . there might be a reason.. what happens is when the omp sensor on the s5 goes it fries the ecu. that might explain why pretty much every sensor is tripped . just another shot in the dark but i thought that i would throw that out there. but do the smallest thing first . if it solves the problem then you know im wrong

Thanks to everyone for the advice, I will follow through and let you all know. Problems continue. BTW the car is an autoshifter
If the ecu were fried, wouldn' t the car simply not run at all?
