Have you found out what was causing the problem? I recently started experiencing the same thing and was told the throttle body needs cleaned. It happens at random but it doesn't do it often
If it's adding actual gas it's seeing an air leak or thinks it does. Maybe MAP or the MAF?
How would I check if it is either of those things? The MAF is connected to the intake, right? I just have a stock setup
You can clean the wire element in the MAF with some residue free cleaner. MAP should set a code, maybe.
So far so good. I haven't noticed the mpg and torque numbers rising after cleaning that, so it must have done the trick! Thanks....would a dirty air filter possibly cause that as well? Looks like mine does need to be replaced lol
The MAF uses a small heated wire to measure air flow. It measures the cooling affect of more or less air passing over it. When they get dirty they are insulated and slow to react.
AWESOME!! Thanks man =]
