Ok so i have checked the tsrm and searched the website, no luck. I have a 1987 turbo targa with 3 inch downpipe, wastegate shimmed to 11 psi apexi intake and stock everything else. I do not have a check engine light on but do get the codes in supermonitor after taking battery cable off for a while. I recently put on a new afm. the cruise stopped working about 3 weeks ago before i shimmed the wastegate. the light on dash panel comes on when i hit cruise rocker switch but nothing happens when i hit steering wheeel "set" could all this be related? I feel dumb for saying this but i really dont understand the instructions that the tsrm gives to check cruise operation. any help or insight or guesses would help. thanks!
