    do a DME reset to adjust to the elevation change, you could have damaged the spark plug by not having it in there properly with oil and exhaust blowby. i would replace all the plugs. the intake leaks could have caused some damage to the engine with silicon particulates, get some molybdenum disulfide oil additive to alleviate it.

    Made more progress today.

    I went through the sensor list to just double check. Two that I tested came back way out of test limits:Crank position and Oxygen sensor. The CPS is supposed to read 1280 ohms and I tested it at 400 ohms its only allowed plus or minus 10%. The Oxygen sensor had no resistance at the white wires. ground was also disconnected. The CPS also had a lot of gunk on the end of it that was touching the ring.

    I'm kinda stuck with the Air boot the way it is. Same way with the CPS, nobody has it up here. I duck taped it and made some progress, its not leaking. Nobody has it here.

    As for the Computer, I disconnected the battery for a half hour to clear codes.

    Whats the Resistance reading for the Cam Position sensor?

    I put the New O2 sensor on it now it takes a whole lot shorter time to start. But its still shaking the whole car.

    I'm thinking that I have to change some vacuum hoses due to some sucking noises on the right side of the Throttle Body.

    How much of a pain is it to pull the Intake?
