hey everyone got a 99 5.2l dakota 5spd 2wd. when i drove it this morning it had some vibration under acceleration and actually when in neutral and revving the motor it still vibrates. it ran great last night even..any thoughts? no check engine lights and its not an exhaust rattle..my current ideas are bad spark plugs, motor mounts, or harmonic balancer..not sure what else it could be. any insight would be greatly appreciated

 

any engine noise associated with vibration?motor mounts good place to start, not sure how to check a harmonic balancer. spark plugs could be misfiring but that should throw a code, check out the wires??

 

the wires look ok...it doesnt vibrate at idle..i just kinda felt like if it was motor mounts the issue wouldnt have snuck up on me so suddenly..im trying to fig out how to get a look at them now..maybe jacking up the car and looking from underneath..i can sort of see them from above (i think) and they look fine but who knows

 

an old thing my dad allways said first " check the easyest and cheapest things first" second " the last thing worked on" my bet is on plugs/wires.

 

Yeah it was the plugs...they were awful. Got some champion coppers and some Bosch wires. runs great! I hope .045 gap was close enough

 

Glad you got it fixed.. Makes you feel good huh? Stick around alot of good guys willing to help other ppl here on this site.. just don't feed the trolls.. :P LOL!

 

Thanks. I'm sure I'll be asking more questions. Got lots of plans and very little money. Ha. Got an SCT tuner coming (for half price) and eventually I might try my hand at headers and true duals. Then fix my bouncy suspension which i had hoped putting new shocks would fix..Its lowered 4" in front/5"rear. Still bouncy kinda.
