1992 190E 2.6 - Crank position sensor?

[klaus kallas]

Hello all,

I'm more a diesel guy, so forgive my ignorance here. Where is the crank position sensor on a '92 2.6?

The car runs PERFECT (when it runs) but will sometimes stall, run rough, and fall on its face. When attempting starting during these episodes, it will "skip" and occasionally backfire. I've checked the OVP relay, vacuum, and other such obvious things but it just seems to be getting an odd fire. Tends to happen more when at operating temp. but sometimes at cold start as well.

Thanks!
Klaus
