Chevrolet Repair: about my Chevy pick up, chevy pickup, scan tool

Question
I been having problems with my 1998 chevy Pickup misfiring when the vehicle is cold. I have tune it up and still there is no change. So I am wondering if you may know what the problem is with my vehicle?

Answer
Hi Brian.... you will need to check on a scan tool to see which cyl is misfiring...once you know which one check the plug/wire and the cap to see if maybe you have a bad one....also check the inj pulse while the scan tool in on see if you have a fuel problem to that cyl. check codes as well. if misfire goes away once warm then check connection to the coil for corrosion...or a bad coil...hope this helps
