I have been having an erratic miss that comes and goes but had been getting worse. I took the Opti out and apart and the Rotor looks fried on one edge and there are slight deposits on the cap. Would this cause a miss? The sensor and wheel look brand new. This Opti only has about 4000 miles on it. Can the sensor be bad and is that the problem on these? I have taken apart Optis before that are completely rusted and still running so I am wondering if should just replace the cap & rotor or the whole unit?

 

By doing a search for opti on the board and seeing what symptoms people are having. Im too lazy to list them from the top of my head.

 

Car suddenly dies and won't restart
Starts but immediately dies
Extended cranking to start
Rough idle
Sputtering
Backfiring
Trouble reaching higher rpm
Black smoke from exhaust
Poor performance with car warmed up
Weak plug wire spark
Codes 16, 36, and 42 may be set

Only a few that i'v heard.

 

Thanks for the replys, I've been having a few of problems listed, Trouble reaching higher revs and poor performance after waring up. So is it the sensor that goes bad? I guess I'll be replacing it.
