I have a 93 escort lx 1.9. After setting at idle for a few minutes the
engine will rev up then slow back down over and over. It revs for about 2
secs then dies back down. If you give it a little gas it clears up and
stops. Any help would be appreciated. Thanks in advance.
I had a van that did that and the ranger does that too.. for the life of me
i dont know what it is i dont see it as a problem however.
My new f250 does not do it (yet) i have a feeling that it will some day.
I would like to know what this is as well... what causes it. I mean just
stabbing at it ~ can be a sticky choke... but since it is so repetitive in
timing it seems almost like an electrical problem.
I had this problem with my 91 Sierra DOHC 2.0i - turned out to be the 02
sensor - don't know if your car has one - on the sierra it was situated
under the bonnet on the right wing closest to the windscreen. This may not
help but I hope it does.
