Throwing codes, fans staying on Hi guys, I recently removed all the EGR and Air components on my 93 Formula. After doing so my check engine light comes on about 30 seconds after start up and the fans kick into high and constantly stay on. I scanned the codes at my friends shop and it's throwing code 26- "Quad Driver Module 1 Fault" and code 22- "Throttle position Sensor". Is there anything I can do to fix this or clear the codes other then getting a chip burned by pcmforless so my car stops running with the fans on and in limp mode? Thanks!

You might be able to fix the TPS sensor problem and use a good fuse and relay for the AIR system, but you will need the retune to get rid of the EGR issue. The fans will turn off when the codes are gone.

So basically the tune is the only way to get the car running right again? We tried to clear the codes on my buddies scanner, the light would go out and the fans would go off, then come back on in about 30 seconds. Would plugging the EGR solenoid back in do anything to help this?
