1989 Mercury Cougar LS question....

I had just replaced the head gaskets in this car(3.8 v6) and now when I start it up and it runs for a few minutes it idles high...around

2,000. Didn?t have this problem before. Also when running it idles a little high too...when I take my foot off the brake while it?s in drive, it pulls quite a bit. Anyway, also the spedometer isn?t working now too. Any ideas??

Well it was a vacuum leak that was causing the car too idle too high, but now I have another problem. It has an electronic dash, and when I was done putting everything together after putting the head gaskets on...I started the car and drove it and the speedometer was working fine plus it was showing me the average miles per gallon, how much gas is in the tank, etc... well, a little after that the speedometer stoped working. Any idea what would make the speedometer and dash not work? It?s lit up and everything, just not telling me how fast I?m going. So, any ideas...and thanks too everyone for the help. I really appreciate it.

Thanks Alot, James

Any clue on the speedometer anyone?

Sounds like something got re-connected not quite tight enough and it fell off/loosened up to the point of inoperability, or something got munged while you were working on something near it. Check everything you worked on, and anything near there, cables, electrical connectors, etc.

...or it could be a coincidental failure unrelated to the work you did.

What, exactly, is displayed on the dash? Zeros? Any numbers? No numbers? Is there a zero for speed and it just stays zero when you are driving?

If the backlight for the display is working but there are no digits displayed (no LCD segments at all) then I would suspect that something electrical between the computer and the display is preventing a readout. If, OTOH, there is a zero displayed for speed, that doesn't change when you are driving, you know the readout is probably OK and you should look to see if maybe the speedometer cable got knocked loose.

It just displays zero the entire time...it was working when we first started it back up...but I?ll check the cables and all and see if something came loose.
