SRV1's latest status update: 2legit2quit
| | Need a tune for my 90?
The usual, heads, cam, intake and exhaust. The car has the usual idle surging and stalling. I have cleaned the salt and pepper connectors, swapped and adjusted two TPS's, changed IAC with 4 different ones, cleaned the throttle body, adjusted the timing to factory and to 14 degrees, changed the IAT sensor, changed the coolant temp sensor, changed the pickup in the distributor, swapped another good distributor, changed the EGR position sensor, checked for vacuum leaks, swapped ignition coils, swapped MAF sensors and adjusted FPR to 40 PSI and just about everything and the car still hunts but not as bad when I cleaned the salt and pepper connectors. It runs fine off idle but will surge randomly when at idle, cold or warmed up. Also, I'm running the Anderson cam B21 if that helps. So do I need a tune? This issue did not start until I changed from the factory cam. Other friends have aftermarket cams in their cars and have zero idle issues.
