i am getting the code 26 after doing the paper clip test on my 1993 caprice with the lo5 5.7L motor. I had it rebuild about 6 years ago and there is only about 3000 miles on the motor also a new rebuilt transwith a shif kit. I got the the quad-driver module (computer) circuit #1 fault.Dose this mean my computer in my car is fryed/not working corectally because i have had rough idle when started and then when put into drive the computer takes over and makes the idle at 1000 rps.Would anyting else cause the motor act like this?
