engine trouble, need serious help!

Asked by Mar 03, 2016 at 07:49 PM about the 2003 Dodge Ram 1500 SLT SB 4WD

Question type: Maintenance & Repair

Hey everyone!
         I was having a problem with  my 03' ram 1500 with a 4.7 magnum
engine, so i decided to do a tune up by cleaning the throttle body and
changing the plugs. the coils seemed to be just fine (no cracks or damaged,
put in the way i took them out) and then when i turned the truck over it was
running worse than before. Before the tune up, everytime i went to accelerate
the rpm's would drop and then go back up. Now i put the pedal to the floor
and go nowhere fast. and my exhaust sounds completely different and i have
no idea what else to do, please help!!

you did put just a dab of dielectric grease on the coil over boots and coated them, right?

no i didn't use any

Then you may have high energy spark leaking around the boots.

what can i do about the rpm's dropping then rising ?

The ECM will have to readjust the idle itself after it starts running better, this can take as long as 30 minutes of normal driving. You did use throttle body cleaner and not some other cleaner right?

i used the throttle body cleaner and not any other cleaner

Ok good, I was hoping you did that, did you reset the computer after the tune up and cleaning? If not you can go to most parts stores and they can clear the system, usually it is free. Then you can run the relearn protocol, but put some of the dielectric grease before you do anything else.
