    Default 99 no start

    My daughter reported the 99 wouldn't start. I notice a slow crank the other day so I assumed it was the battery.

    I went to try it this morning and it would crank and crank but wouldn't try to start.

    I remembered the TPS issue we had a year (or more) ago. I tried starting it by giving it gas. It started, ran rough and then lined out. Wouldn't hold an idle though.

    After running it a couple of minutes it started idling.

    I have a new IAC so since I hear this is the most common cause for bad or no idle I swapped in the other one.

    With the throttle body off I did clean it with throttle body cleaner.

    Blow by? Normal or not? Have not noticed any smoking.

    I had the original TPS so I put that one on and it starts, idles low for 2 to 3 seconds and then idles normal.

    I'm thinking I need to replace the TPS.

    I agree with the TPS being wonky, replaced mine with a orielly BDS(i think) brand about 5 times and finally got one from the stealership and the issues stopped.

    Matt said he was running the lifetime warentee BWD TPS from Oreily's. Frankly until the post above I didn't know this wasn't a dealer item!

    Replaced it a few moments ago. Starting and idle is back to normal.
