Water box rpm issue

[Larry Merk]

We had the same issue with our car after making a lot of changes. While trying to diagnose the cause we disconnected the alternator and the problem went away. A quick test with a large jumper wire proved that was the problem. We move the alternator wire well away from the distributor for a permanent fix. Hope your solution is as easy as ours was.

Our car acted like it was on the 2 step. The engine RPM got to about 3500 and would go no higher. We breathed a big sigh of relief when we found the cause and solution within just a few minutes.
