Hello, I have an 08 mazda3 with a 120,000 miles. Last wee hit was stalling on highway so I put in sea foam with 91 Octane gas and it running fine now . I read that dirty maf could stall a car. My question is that since it running fine, should I mess with maf? And if yes, how much should I spray on and how far from the spray to the maf wire.

Thank you

it wouldn't hurt to try. Just follow the directions on the can. make sure you use an actual maf cleaner.
