2001 s-10 4.3 miss and p0300

got a 2001 s-10 with the 4.3l had miss and changed cap,rotor, and plugs.ran fine for 2 months and now runs really rough,have to keep rpm at 1500 or high to keep truck running.checked codes and had a code for crank sensor,replaced that and code went away.test drove and had code p0300/multiple misfire.checked on here and alot of people say to use only ac/delco cap and rotor, i just got autozone ones.thanks in advance for the help

This is why people on here say to use AC Delco ignition parts and NOT to use Autozone ignition parts if you want your vehicle to run: http://www.automotiveforums.com/vbulletin/showthread.php?p=6100044#post6100044

Get an AC Delco cap and rotor on there and let us know if you still have problems.

ac delco cap and rotor fixed the problem,thanks for the advice.
