Hello i was wondering what this could be whenever my truck is cold my truck does not have the little miss but when it gets drove about 15 minutes and i come to a idle my truck starts having a slight miss. but not driving down the road? could it be dirty injectors, crankshaft sensor,. i have good fuel pressure. truck hasnt been throwing any codes. The weird thing is that it has been doing this now for a whole year but have not had no driving issues just a little miss at idle. Any help or information would be appreciated. Thank You.

 

it just bothers me so bad. and some time the miss is kind of hard and it makes my truck sound like crap when idleing?

 

Mine has a slite miss at idle and every now and then it will miss hard. I scanded it 20 times and never saw the voltage diff. Ecm has 13.70 going in and 11.49 at vp. Going in shop Tues.

 

will that make my truck miss if my voltage is different from the ecm to the vp. and how do you check the voltage on the ecm and vp44?
