Stalling at highway speed
 

Hi guys. 2000 MC SS 3.8 here. Around town the car runs tip top. out on the highway it stalls out like the key was shut off at 65mph. It throws a code for the MAF sensor. If you clear the code it fires right back up and runs perfect for about a mile. Ive been tossing it up into neutral, clearing the code, firing it back up and tossing it in gear for a a little while. The MAF has been swapped with a used one and 2 new ones. Same ordeal. There are no other codes stored on the car and otherwise runs like a brand new car. It only does it on the highway and only once you get to a steady cruising speed. :confused:

What type of MAF sensor did you use? Our 03 did similar and we had a dormant maf. I bought an original not reman acdelco MAF and it's been great since!

not first time I have heard of these cars not liking anything other than AC maf sensors
