Have a 2001 chevy S-10 blazer 4.3 V-6. fuel injected When you first start the motor it idles fine and high rpm is ok. As the motor warms up the idle gets rough but high rpm is ok. Seems like it is running rich. It just started this about 2 wks ago. Can someone tell me what to look for to correct the problem. Thanks ranrodder

I would start with checking it for codes..If you do not have a scanner, most part stores will have one they can check it with. Once you have the codes post back to this thread with them if there is any.
