Something I noticed today and haven't before
I was sitting with the car at idle, it was fluctuating between 500 and 800 revs going brum, brum, if you know what I mean. When I put the windscreen wipers off, the heaters off, the rear windscreen demister off and the lights off it went to 600 revs and stayed there, no more brum brum, just a steady purr. Is this normal?
I can smell burning........... |

Your car should be ticking over at a visible and constant 750 RPM regardless of the electrical load. There may be a slight momentary fluctuation as the ECU works to compensate for any extra load on the engine by balancing the RPM rate.
Smell of burning in a car is not normal. Get it checked asap. |

Yeah, it usually ticks over at 600rpm no matter what. I'll keep an eye on it.
Should have said I can smell burning in the living room but I think it's cos I've put my fire light on for the first time in about a year. |

So there is no burning in the 75?

I had a similar problem, and ultimately it turned out to be the TPS (throttle position sensor), but clean the IAC (idle air control) valve first, which is simple to do. If that's OK put her on the testbook and see what fault codes come up. PO 122 is the TPS. Last edited by RowlandOz; 16th November 2006 at 20:30.. Reason: omitted words |
