#4 of 8 Re: 1990 cougar 3.8 high idle [hdion75] by mzannoni Jan 13, 2007 (9:42 am)
Replying to: hdion75 (Nov 06, 2006 8:04 pm) Hi. Have you figured this out. I have the exact problem with my '92 Cougar. It seemed somewhat high since I've had it (about 3 months), but now it idles at 2500 in Park, about 1200 in drive with brake on. Cannot find any vac leak, but voltage is really high to the injectors. Put in an identical junkyard brain box, no change. (Of course it could also be bad . . .). Please let me know if you've made progress or had success in fixing. Thx.

Drove me nuts, but found that if I pulled the ecm fuse, then started the engine, shut it down, put the fuse back, then did a reset sequence (depress accelerator slightly, start engine, run for three seconds, shut off for ten seconds, then restart) it went back to normal and has run fine for months.

Replying to: mbents (Apr 26, 2007 1:53 pm) It works............ I have a 93 rodeo and the ecm fuse trick works. My Rodeo would rev to 2500 rpm when the clutch was pressed, sounded like John Force staging at the Gator nationals ! Thanks

Replying to: mbents (Apr 26, 2007 1:53 pm) Thanks very much for this answer. I just tried it on my '94 Rodeo, and it worked like a charm. After weeks of tracking vacuum hoses and checking connections without finding any solution, it's finally now not zooming up to 3,000 RPM every time it idles.   The only slight difference is that when I tried to start it without the ECM fuse in place, it wouldn't. So, I just cranked it a few seconds and stopped. Then put the fuse back in place and followed the rest of the directions. Bingo! Test drive proved no more problem.   Thanks, Thanks.
