Engine Idle Surge

Green92LX · 01-31-2001, 12:05 PM

The 10-pin connector is the wiring harness that connects to your motor right next to the EGR, in that space behind the intake. It should be white and black. I used brake kleen to clean mine, its supposed to be safe for electronics, but they do sell cleaner for this application. Take it apart and check to see if there is any corrosion on the connections themselves, not just the outside of the connectors.
Vacuum leaks are a little harder. I was lucky because when I started to play around in there when I found my leak,one of mine broke off with minimal effort. I changed that line and was done with it. If you do have a leak, you should be able to hear it if you pay VERY close attention. Just be careful with those lines. The hardened plastic lines break easy, even if they are OK before you start jiggling them around.

Let me know if you have any other questions...
