99 blazer stalling problem
I have a problem with my truck. Each time the thermostat opens the engine dies. As soon as the engine cools, even a small amount, the truck will start and once again when it comes up to temp the engine will die. Any sugestions? THANKS

Re: 99 blazer stalling problem
Welcome to the forum.
How is the temp when this happens - normal? If coolant level dropping at all then intake could be leaking internal as it heats up. There is a temp sensor in the air intake (small one) and that tells the computer temp to set mixture along with other sensors - but a code should be turning the SES light on - any codes? Clean the MAF sensor (big one in 2" block) in air intake with spray cleaner. Thats a few easy things.

Re: 99 blazer stalling problem
Thank-you for your help. I cleaned the maf sensor and although it hesitated the first time it came up to temp it kept running. We then left the engine running through the cycle a number of times. After about a hour I took it on the road and 10 min. into the drive the truck began to backfire through the intake and would not rev up.
 I have since been informed that the it has been getting progressivly worse fuel mileage. I am now off to review the forums that concern themselves with this problem. Once again, Thanks a Lot.
