Title: Idling issue
Post by: riz on April 10, 2009, 05:29:24 pm

My Idling seems to have gone lumpy also the Revs rise then drop when stationary. Is this a TDC issue?
Only noticed it today, power seems to be ok, maybe a slight MPG drop but hard to  tell to be honest!!!

my first thought would be to change the spark plugs.

Check to see what your what your long term fuel trims are set to.  If they are a long way out you could have a problem with your MAF sensor.

Also try unplugging the MAF and see if the problem persists at idle.
