My explorer's engine will die occasionally when driving in warm temperatures.

Great idea! Thank you, I will give this a try.

your welcome.post findings.

I checked for vacum leaks, and couldn't find any. The Explorer doesn't appear to have too many vacum lines. I purchased a torx security bit from Sears, and pulled out the mass air flow sensor. It did appear to be lightly coated with some residue. I used the CRC Mass Air Flow cleaner per the instructions. After I reassembled, and saw the check engine light on, I hooked up a code reader meter. I cleared the check engine light, and ran the engine for a while. It seems to run well. I'm having my wife drive it for a few days, and check to see if the Check engine light comes on again. So far, it hasn't. After doing that job, I did the same thing to my son's 1998 Expedition. It had the Cheack Engine light on for a while. I took apart the air cleaner assembly, cleaned the Mass Air flow sensor, and cleaned out the inside of the air filter canister. After reassembly, the check engine light turned off. Thanks for the great tips, It saved a bundle of money that I would have spent at a garage.

you welcome,good work!
