Hello All! I have a 92 S10 Blazer the starts and then shuts off. If I put my foot on the gas just a little to keep it running it's fine. After 30 seconds or more she will idle fine. Untill I shut the Blazer off. Then the process starts all over again. I cleaned the EGR valve and even installed a Temporary block off plate. I also replaced the MAP sensor. It's better as it wouldn't idle at all before.
Any ideas???

 

Fuel pressure ok?? Test for vacuum leaks?

 

I replaced the IAC motor and she now stays running!! A lil costly at $120.00 but worth it!

 

wow you really over paid for that. autozone has them for 64.99

 

Thanks for the info but I do not buy from Autozone. I get my parts from a local little parts store here in my home town. I pay a lil more but I'm helping the guys stay in business. Plus I have been dealing with them since I was a child when my Father bought his parts there.


Thanks Steve

 

Did you try cleaning the old one with brake cleaner first? they usually just get dirty.
