How about a s---s---s---s---s---s---surge?
It happened to me on the highway twice at 60-65mph.
Its happened with 2 different MAFS/intakes.
Weather was same both times.
My theory is the rough idle and surging are because of the ecm/dis losing track of ignition timing......Am I right?
My tach sometimes doesn't work, and the 6-try start thing happens like 3 times a week.....
I'm waiting for my new CPS in the mail......
