I cleaned the MAF in my '99 3.0 Ranger twice in the past two months. The first time with just carb cleaner, the second time with carb cleaner and a Q-tip. I also used Valvoline's SynPower fuel and intake cleaners.
The ping is barely noticeable when the air is off. When I have the air on (needed for the Las Vegas summer) and I'm going between 45-65 the ping is loud and clear.
Does anybody have any other suggestions?
This is driving me crazy.
