Thanks in Advance

vacumme leak?

Cliff Harris

The idle speed is controlled by the ECM with the IAC. The ECM can lose control if there is a vacuum leak.

I don't understand the TPS of -0.3. What does that mean? What are the units? Usually TPS is expressed in percent. Is that -0.3%?

That was it! I have not ran it down yet, but I went and got myself a gage and confirmed it. I haven't found where it is yet but tried with starter fluid.

It's running as expected this am after looking for the leak. Weird but ok. I hate trying to run down this type of intermittent issue.

Thanks Again!

I don't know? It seems to be running much better this AM. I'm sure I have a vacuum leak but have not located it yet. Maybe the TPS was over compensating for the leak and trying to correct the idle speed. My un-educated guess tho...

Mine had a high idle and it was the throttle body , loose shaft one one end. It was only noticeable after it warmed up. Try holding or moving the throttle body where the linkage is when it's at idle.
