    Just an FYI.

    I had a wandering idle when cold in the morning, low-high-low-high for about 3 minutes. I replaced the TPS and that fixed it.

    After changing the cam, and rebuilding the heads with bigger valves my trucks idle was up and down. A quick look using WINALDL showed a lean condition at idle. Upped the fuel pressure to 17.8 psi, and no more problem.
