So did you get that hot dog cooker yet?

Thanks for the posts!!

I just ordered a manual from Amazon.com and now maybe I'll have something to refer to.

I'll also check the wiring harness and see if I can find the wires.... the posts I've read say there should be two one before the cat and one after... I'll be getting them and putting them on.

I'm hoping this will make Leroy Duece feel and run better...

Thanks again!!! I'll provide updates as I proceed.

I dont think there is one after the cat. OBD II vehicles have that.

Ok... I found the sensor this evening and I soaked in WD 40 and I've ordered a new sensor. I hope this will help.

Right now the motor surges at idle and the idle is fast. I have the top off the air controller and it is rotating to a position which causes the engine to run a bit fast. I can smell a bit of gasoline when it is running so I know it is running rich. Also only getting around 14 mpg... I hope this o2 sensor helps.

If you have any other ideas, please post.

Thanks

Remember to pull your EFI fuse by the driver's kickpanel for about 10 sec to clear any codes. The ECU will recalibrate its loop with the new sensor. Check out the emissions tech articles at www.autoshop101.com on this subject.
