Have the car running, unplug the MAF and see what happens, do you have any oil around the spark plugs?
Yea , It maybe the Vanos, depends on mileage and service history it normally goes around 100K.....but it will probably only be the seals and not the unit....
Ok, there isnt any oil around the spark plugs, and unplugging the MAF caused the engine to rev a tad, return to normal, but then continued again with the rough idle and almost stalling, so I dont think thats it.
The car has 164,000 miles on it. Bought it from my aunt a year and a half ago with no problems. Im not sure what she had done it to it, but she took very good care of it.
Should I start with what rajk9800 said by replacing gaskets, etc.?
Also, is it simple to diagnose whether or not its the vanos?
Thanks for the help, much appreciated.
