Question about 1985 Chevrolet Corvette
-did you check the egr valve to se if it is stuck open? it sounds like it. black smoke out the tailpipe?
- was there a code 42 present? if code 42 is present then change the computer.
- the distributor shaft magnet used to crack and cause a false signal for the computer too. remove the dist. cap and rotor. look and see the 8 fingers wrapped arround the magnet on the part under the rotor? look in between the fingers and see if the edges of the magnet are cracked. if so then you just need to replace the shaft assembly or the distributor.
check these and get back to me if needed. Scott
