Hi, I am new to this site and also new to owning a 91 Blazer with a 350. The truck runs great but every morning I have a hard time getting it started. When I first crank it over, it starts and then immediately dies. I give it some gas while cranking it over again and it starts right up. I let off the pedal and it dies. It does this a few times before idling on its own. When it does it has a really rough idle..kinda like..babababa...ba....ba...ba.....babababa....ba..ba..ba. use your imagination. After letting it sit doing that for a while it cleans up its act and idles properly. Also after idling and warming up, its drive great. What could be my problem? I went to autozone and they found a TPS code and a low temp code. I think they were codes 15 and 22. But for some reason I think it is my IAC. What do you think?
