    Help! Still rough at idle, check engine light

    Recently my RXP-X 260 was throwing a P0106 code. Took it into the dealership and had it looked at by a friend. Pressure test on the intercooler was good. Intake Pressure Sensor appeared to be good. Finally the ski stopped throwing the code after a new throttle body was put in.

    So today I gave it a test ride. Ran great for about 25 minutes. Rode it hard for the last 5 minutes and decided to head in. Soon as I dropped it down to idle on the way home the check engine lamp comes on again and the ski starts idling rough. RPMs going down as low as 1500 but mostly bogging between 1600-1700. I can give it gas and when I steady it up around 3000 RPM or more the check engine goes off and it runs fine. Drop back down to idle and the light comes on again.

    Any ideas here? Could this be a short in the wire harness? Only other thing to report is that "Low Oil Pressure" flashes when I start the ski up but it doesn't throw a code and then goes away immediately.

    Have you replaced the spark plugs?

    I don't believe I replaced them following the accident. I'll swap them out tomorrow just in case. But would plugs really be able to throw a P106 Intake Pressure code? Also, the problem seems to be somewhat intermittent, I would think bad plugs would be more constant. My gut is telling me it's still something electrical.

    If your MAP sensor goes bad it will idle like shit.

    I've searched through the forum and unless I'm using the wrong keywords, I can't really find any other instances of a MAP sensor going bad. If it were a MAP sensor gone bad, do you think it respond intermittently like this? In my case the problem has gone away twice now and then come back.

    I thought about that, but since the problem has disappeared twice and then come back, I don't think it's crack. Intermittent problems like that usually lead me to believe they are electrical issues.

    Do you mean the actual pressure? Or what code & error it's showing?
