1996 Pontiac Grand Prix surging

\015 The engine seems to be surging. The speed doesn't matter, sometimes 50 mph, sometimes 30mph. The odometer shows the rps are going crazy for a few seconds, then goes back to normal. Could it be the transmission modulator valve? I assume this has an electrical one, not like the older models.\015 Posted / edited by AnonymousUser on : 20-05-2019

Answers :

NO the problem is in the ignition coil or the ignition module which is right under the coil pack
