My 96 c280 just started missing, I think it's cylinder #1. The check engine light is not illuminated though.
I started by taking out the intake pipe, and coil cover off to inspect. I found that the coil-pack closest to the firewall has lime build up along with the plug wire. I cleaned them both up and reinstalled everything. After I put everything back together, the strangest thing happened. My transmission will not shift on its own, I have to shift it manually.(by releasing the accelerator)
The car is still missing, I'm going to pick up a new coil tomorrow.
Anyone ever had this issue before? (the transmission issue)
I did manage to break one of the vacuum lines while moving them out of the way, but I replaced the damaged lines.
Where should I start to fix the shifting issue?
