any ideas?????
 

ok i have a 97 s-10 blazer with a 4.3L auto trans and is also 4x4. when it cold it starts right up, but when it warms up and you shut it off it take a lil bit to get it started again. then i also have a problem with the motor missing before it shifs to 2nd and sometimes to 3rd. any one have any ideas? its not even trowing a code on the obd2 ports..... :( id hate to get rid of it if it isnt something major...

It could be the fuel pump or fuel pressure regulator.

Make sure the all the connections ao the trans are clean and tight. My mom had a '96 that ran poorly and had trans trouble after a trans swap. One of the connections on the trans was loose. Opps
