But when i reset the ECU, my engine bogs for a while. After a few minutes of driving, its goes away. is that normal?
Is your car stock, or do you have a CAI
. If you have a CAI
, it's the ECU learning the new airflow pattern.
Be careful with the brake cleaner, it can dissolve the plastic and might melt the contact points.
Never had any problems with any non-chlorinated brake cleaners. I just spray inside the MAFS, using the force of the cleaner to push out any dirt,let it soak for a few minutes, then shake out any excess and reinstall. Been doing this for maybe 30K with no MAFS related problems.
Brake cleaner will take the paint off metal pieces on your car, do you really want to spray that into a tiny electrical instrument?
Good thing the MAFS isn't painted.
The plastic in the engine bay is made to handle any kind of fluid that may be spilled on it, including brake fluid which is also known to eat paint.
