idle studder...
hi all, i drive a 97' ranger xlt 4.0 liter 5 spd
lately ive been noticing that ive developed a studder and it is most noticeable at idle...
when im dead stopped, the engine starts to wobble/studder a little and while watching the tach it drops about 400 rpms, gets close to stalling and then the comp takes over and compensates. rinse then repeat... haha
im leaning towards a bad sensor but i would like your input... what do yall think?
plugs and wires are new and air filter is clean.
thanks a ton for the help in advance...

Assuming you have no stored codes, a dirty IAC solenoid would be a good thing to look into. They are easy to clean and the price is right. I would also consider retorquing the lower intake; they have a history of the bolts loosening over time and developing a vacuum leak. Finally, it's the time of the year where condensation is prone to developing in the gas tank. A 93 cent bottle of Heat will rule this possibility out.

If you look in my gallery there is a pic of me pointing to a vac line. In the upper R/H corner of that pic you will see a silver colored cylindrical device; this is the IAC solenoid. Yours may be a different color; it's the location that is of interest.

I just had the same thing happen to my 05. The Idler is supposed to move a little. Mine was clicking at Idle and I swore it was the Idler. Nope, I took it to the dealer and it was the Belt. They replaced it and no noise anymore. They said there was a small nick in the belt but I did not see it.
