Question about 1996 Pontiac Grand Prix
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.
NO the problem is in the ignition coil or the ignition module which is right under the coil pack
