Like I stated earlier this is a truck I just purchased, it is a 1996 V10 68,000 miles very well-maintained truck but I noticed at idle I can feel a vibration in the seat of my pants, open the hood I also can feel it on the engine I'm going to start with plugs and plug wires hoping for the best there any other thoughts?

 

Have you hooked up a scanner yet? Any codes?

 

not yet just bought the truck yesterday, I will though

 

Iat sensor may need to be cleaned

 

scanner goin on monday...what and where is iat sensor

 

Intake Air temp sensor. Passenger side, toward the front, on the intake manifold.

 

Thank you I will check it out what is the best way to clean it electrical cleaner carb cleaner?

 

Carb cleaner, or Brake cleaner. All it does is read air temp in the intake. It shouldn't be able to cause too many problems...... Once the PCM drops into closed loop, is shouldn't matter at all.

 

The only sensor i see is on the intake manifold is in the middle two screws holding it with a small wiring loom snapped into it?,
the truck runs beautifully it's just more of an irritant you can put your hand on the intake and feel a slight vibration, And the exhaust on this is factory stock and is quite quiet and I swear I can hear it coming off exhaust but could be my imagination, as soon as you accelerate it all it's gone I'm assuming because of the harmonics it may still be there but just not noticeable

 

IAT just screws into the intake.

Oh, wait.... yours is a V-10....... No clue where the IAT is on that.....

See what your plugs look like. Changing them sure won't hurt. Skip the rare-earth plugs, not necessary, and some of our trucks just don't like 'em.
