1992 Cadillac DeVille Touring 4.9L Poor Idle Quality, Hesitation, Cuts out, Stall, Misfire, sudden timing retard
This car runs fine for a few minuites and then retards the timing and also loses consistant spark ( timing light flashes randomly when trying to follow advance curve.)It runs poorly backfiring and spiting back through the intake. PLEASE HELP! :~O
