Blinker effects rpm's

coot1 · #1 (**permalink**) 01-31-2011, 04:53 PM

I have a friend with a 2000 F250 4x4, manual tranny, 7.3 that when he puts on a turn signal the engine surges in unison with the blinker. Any ideas would be appreciated.

My friend is at his wits end. He thinks it maybe a wiring harness issue. I figured I would give this forum a try because I could see now way that turn signals could effect the engine performance.

I had that happen once, TC would unlock when I turned the right blinker on. Then I replaced a burnt out tail light, and it went away.
