To all the people that talk about cleaning your MAF. Thank you . I had a kn drop in filter for about 4500 miles, the truck ran better at first but seem to run slower and gas mileage slipped as time rolled by. I bought an AFE CAI to see if that helped the problem and it helped a little but the truck was way louder and seemed to not be able to handle the air. I CLEANED the Maf and WOW!!! Truck is smooth and quick, nice sound when you put the foot to the floor And the mileage is back up!! Average is 17.1 with a soft touch all around town driving, measured the old fashioned way. I can't wait to see what is on the Highway.
This s a great place to learn about our trucks for a non mechanics like me..

 

may be a dumb question but how did you clean it?
how many km's on the truck before cleaning it?

 

I had the K&N drop in for about 3000 miles then I threw it away and bought the AFE . I put maybe 1000 or so miles on the AFE before I cleaned my Maf.
I just unscrewed it from the air tube and Lightly sprayed it with MAF cleaner, let it dry and re installed it. Maybe I should have pulled off the battery cable and reset the computer,I don't know but it worked out fine.

 

so its just a simple spray? hmm.

 

crc electrical contact cleaner that's the only thing to use safe for plastic, couple little spray's will do ya. you should be able to get it at any auto parts store.
