Okay, so a little history.

F22b1, eg. Running stock f22b1 OBD1 ecu.

Well, took the car to the track friday. Half way down the track car spit sputtered. Parked it, was running fine. Took it down the track on my slicks and nitrous. Back nitrous backfire. Parked the car, checked the plugs and didnt start back up...got it towed home.

The next morning i changed out the dizzy module. Car cranked up fine. Drive fine. But sometimes at full throttle the car would SHUT off. Just die. Wait a min, and it would start back up. No cel when key turned to on. wait a min and it would.

Well last night, car goes CRAZY with full throttle. Jerking and shaking really bad. Like a rev limited around 4-5. But could take it to red line anywhere under full throttle. Then the car went into limp mode as i was driving it to a friends house. Then just randomly it came out of limp mode while driving down the road. So i changed the module. Same story with the next module. Now its in limp mode again. When it goes into limp mode it throws a solid cell when you jump the ECU service plug. But if you cut it off, cut it on. It only throws a o2 sensor code (not my problem. Been unhooked since day one)

Any ideas?

 

Bump it up i need some help

Unplugged the TPS, Problem quit....

Then on the way home, car went back into limp mode. Solid cell, idles at 2k ALL the time.

 

No one has any ideas?

 

Where Ronj at...he will get this figured out!

 

if i was you i would start with the map sensor and the tps sensor

 

Vacuum leak on the fast idle thing on the obd0 TB's. Nothing was running to it, but it cause a vacuum leak. Im not sure how or why, but sealed it off. And no problems since.
