I Looked On My Lunch Break. Did Not Say Anything About What The Idle Should Be. Is There Any Other Place I Can Look Or Can Any Tell Me What It Should Be? Thanks For The Help.

My guess is that warm idle should be around 800.
I'd check and make sure the throttle body is clean & throttle plate is closing all the way & check for lean codes.

The trottle body is good. I do have the CEL on. Auto zone said it was the #1 O2 sensor. Whould that cause it to idle a little high? Thanks for the info.

Which O-2 code did they pull? Theres a couple of them. If it as an O-2 lean, thats your high idle & you need to figure out why it's running lean.
Not sure, but I think the SOHC has a bad habit of having leaking intake manifold O rings. Do a search on that.

I justed replaced my intake o-rings this weekend it fixed the rough idle and hard start on cold mornings. The CEL was on before I did that so my guess it was running lean. Auto Zone did not give me a code they just said it was bad. As soon as the holidays are over I will get around to replacing the O2 sensor when i get time. Thanks for the help and info 87 XLT. As soon as i replace it I will let you know.
