truck idles funny dies while driving normal sometimes while idleing if i give it gas it stubbles and hesitates like its out of gas and dies i have check code one day got PO107/P1121 i cleared those codes and the next day checked them again and got all new codes PO460/P1636/P1747
P1636 =aux in/output malfucurer control (inductive sig chip comm error indicates the PCM has lost comm w/the inductive sig chip (PCM damaged)
and a couple other cades indicated a poss PCM damage
any info would be helpful thanks

 

Try resetting the codes then take the Batt cable off for about an hour. Also check the grounding to the PCM. Do you have a chip?

 

check your fuses in the engine bay for the pcm (there are two) i had a problem similar where the truck would stall and i got theft codes and went as far as replacing an iac, key transciever, battery, a set of plugs all to find out i had a loose fuse (40 amp maxi fuse, green)
good luck i hope this helps because i went crazy for almost a month. also...hopefully you get more feedback than i did in here...don't forget to try as many different ways to search your problem you will find more help that way...everybody seems to be caught up in lame a$$ issues like "how much air pressure in my slicks" or "i found a lightning paper weight o e-bay"

 

do you hve a chip? if so make sure it's securely taped in, if it's loose you could have this problem
