I recently replaced my intake manifold gasket on my 01 Blazer. We got everything put back together now when I start it and the engine is cold it wants to stall out. Once it gets running and warm I have no other issues with it, I only have this problem when it is cold. Any suggestions?

 

I have the same problem..00 LS Blazer 4WD 4.3L I replaced the fuel pressure regulator and now when it starts, its doing the same as yours...It does start but stalls and then upon a restart, it gets itself up to about 1000 rpms and then it falls back to 500-600 and it runs ok..Im not sure if it is my fuel pump since the pressure is good now...I know it needs to be replaced,, my gas gauge doesn't work..Im gonna try it first. Hope you have some luck as well If so, let me know and ill do the same

 

Fixed the problem went to autozone read code p0118 bad ect sensor. 18 bucks and it's brand new. I replaced my fuel pump last year my advice to you is buy a good one from ACdDelc oor dDelphi don't go cheap.
