Just wanted to check and know if the flight fluctuation in RPM on idle ( around 100 rpm or so ) is normal ?
4.7 engine with F1 gear box. Recently had full service with new sparks , car done 30,000kms and is 2011.
I recently bought the car and after the service I put a can of liqui moly injector cleaner ( the rpm change was prior to this ). Haven’t driven the car much (150kms ) but wanted to make sure nothing is wrong and just natural behaviour .
Does MAF need to be cleaned ?
