Alright was drivin my dads truck tonight and thought it sounded like it developed a slight miss in it at a low rpm. The truck runs good. It is all stock other than a straight pipe. I thought I heard it the other day but didn't think anything bout it. Noticed it a bit worse tonight. Jus put the pipe on it yesterday so maybe thats why it sounded like it got worse today. Does this sound like a cracked injector to ya'll? Its an 06 3500 G56 build date is 8/05. I'm gonna try to crack the lines onit and see if I can tell anything and try not to freeze out here tonight. Any help is greatly appreciated. Thanks

 

DONT CRACK ANY LINES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The pressure in a 3rd gen can penetrate the skin getting diesel into the blood stream AND KILL YOU! VERY IMPORTANT!!!!!!

 

Yeah x2. It might cost a little money, but alot safer. Have a tech @ a dealer check em out.

 

Ok never did get around to crackin the lines any ways. Not real motivated to work when it 20 degrees outside. Got a friend of mine to listen to the truck tonight. At a steady rpm you can hear the miss but accelerating rpms you can't hear it. Truck still runs fine jus like always. Its still runs smooth. I mean you have to listen to the truck to tell it. You can't tell it by just sittin in it. Its got 123k on it. Could it be something else besides injectors? Like lift pump?

 

Injectors, valve lash may need adjusted, tips, but if it were a "real" miss, the ECM would set a code for it. Some engines just have a bad resonate tone to them at certain rpm's.

 

I figured out today that the truck only has 2 good injectors in it. The missin got worse on the way home from work today. Hooked it up to a computer this evenin. Do any of ya'll know the best place to get the best price on new injectors?

 

No warranty? If no warranty, go for aftermarkets. I won't get into which ones or this, that, and the other, but do a search here on DTR. You'll find DAYS worth of reading material!

 

get ready to spend the bucks

 

Nope no warrenty. Truck has 124k on it almost. I haven't had any luck findin after market injectors themselves just tips. There is a shop bout 45 min from the house that has them for $380 ech. Maybe get a set of them if I can't find anything else.

 

Do a search for Flux injectors....... Plenty of reading...... He can repair your old ones and install his tips...
