I have an engine code P0511.

My Michigan Certification M188987. I am a licenced Master Mechanic. I was looking for some info on typical problems since the car still runs great, starts great and Idles great. By the way Im gald I did not donate, I guess you think all people are stupid and need you to tell them and I qoute "I guess the answer is to get it fixed". I really hope your work on cars are better than your advice on this site.

I was only trying to find out if there were simular problems that have been noted. Yes I knew it had something to do with the IAC system. Was just trying to find out how common it was, or maybe a wiring issue. It save a ton of time net-working with others on driveability issues. I find that on many of the vehicles I work on tend to have the same issues. Example. H.E.I. The car cranks and gets gas but will not start. The coil is good, the cap is getting spark from the coil. No spark getting to the plug. This exact problem I had customers getting charged hundreds of dollars to get fix. This problem gained me more customers than I could ever imagine. The problem a $3.00 part and 5 minutes to replace. If you can tell me what the problem is I might be impressed. If you can tell me what exactly happened to the part then I would be impressed. Thank You and have a great day.

I did check the resistance yesterday, and yes I found the resistance was infinite no matter which way I checked. Pins 1/2, 1/3, or 2/3. I figured the motor was shot. As far as carbon or dirt inside, that wasn't the case. I haven't been able to locate the spec's as of yet. Im sure you love what you do, and it is appreciated by many people with questions. I do appreciate your time. As far as impressing me you should try to impress everybody you talk to, at least that is my belief. Anyway the answer is the rotor. Thanks for getting back with me.
