Idle speed erratic / going topless

[Daniel R]

I can't help you on the roof problem, I've never encountered it myself and I'm not the best mechanical mind around.

My advice on the idle is go plug it into an OBD-II and see if an error code comes up. I once tried to self diagnose an "MAF sensor" problem, replaced the part and it turned out to be oxygen sensors. Had to replace those too and it became an expensive exercise for no reason. In retrospect it is a good thing to have all the main sensors replaced.

Both MAFS and oxygen sensors tend to be bigger problems and will most always result in a CEL on the dash. Other things such as air intake temperature sensors (which may or may not be built into MAFS, don't quote me) tend to cause relatively small problems like what you are describing. Either way, OBD-II is the best solution to avoid wasting time and money playing guessing games.

I've had erratic idle speeds for a long time now, it developed into first the car stalling rarely on idle when turning on full lock, then it started stalling every time it reached idle RPM's. It turned out to be a bad MAF, but really it could be anything like Oxygen Sensors.
I agree with running it through a OBD II, it may throw both O2 Sensors and MAF's even if its just one failing. They are linked so one bad part might cause the others to not function properly, thus the codes.

Thanks guys. I did actually connect my ODB scanner/reader up to the car, and it didn't find any codes. I'll take the plunge and order a new MAF sensor, see if that makes any difference.

I now have another problem.....will post a new post as it's unrelated. :ah:
