^^++++ Is the vib there when the motor is cold? Or all the time? gets worse as it warms? HeyYou know's most of the crap I have gone through looking for a very simaler vib. They both know what they are talking about.

 

It does it all the time hot or cold.I would like to fix the skip thats y im looking for answers.Its not the plugs,wires.cap,rotor,fuel fiter, or motor guess i will try the plenum.

 

check plug wire routing. There is a TSB in the faq section about it.

 

Check all the wire ends that go to the injectors, make sure they are on tight, and what kind of history do the injectors have new? old?

 

check engine light came on today when I was riding down the road and had it checked and it was the speed sensor code. would that make me have a vibration? or is that coming on because of the vibration and skipping the motor?

 

I fixed the problem not the trans,cat or the phenum it was a bad plug wire.

 

Good news to read!!! easy and cheap fix for you.

 

ok, I have this exact same issue since getting my transmission rebuilt.... vibrated only in overdrive and usually notice it around 42mph when the rpms are around 1300-1400...The whole truck shakes bad...turn off the overdrive and the issue goes away...I have no pending or current missfire codes? could it still be the wires? I have new ones to install.

 

When my truck was doing that trick, it was an engine miss. No codes for it either. Felt like the truck was trying to shake itself apart. I had just done cap/rotor/wires/plenum, and my problem was two plug wires in the wrong order.... fixed that, and smooth as silk.

 

well I replaced the wires and it still has the same issue.. I only pulled one plug but it looked new... it was a bitch to remove though... I guess thats gonna be my next step as well as the cap and rotor I just replaced 6,000 miles ago.
