Hello. I am a newb here. I wish I could introduce myself under better circumstances, but such is not the case.



I have a 2002 Sable 3.0 24V. The check engine light has been on
for a while (I got it looked at, and the dealer said nothing was wrong
that he could find, so the light remained on).



I went on a long trip to NY last Sunday. I was going 75mhp on the
highway. The car ran normal until about 1 and 1/2 hours in of the
2hr trip up to where I wanted to go. The car then began to run
real rough. It would jerk pretty hard. The RPMs on the tach
would drop (even if I was reving the engine). Shortly after the
jerking and dropping of the RPMs, the engine would just die and I had
to pull over. I restarted the car (to see if I could "reboot the
computer" so-to-speak, thinking I have a ECU or sensor problem) and the
engine ran, but real rough. I revved the engine (the RPMs then
revved up as well). After a few seconds of revving, the engine
then ran normal and I was on my way without problem. However, the
problem would come back at about 30min intervals. I had this
problem twice going up to NY and every 30min on the way back
home.



I called Ford up, and they said it could be a multitude of problems but
they suggested I take a look at the ignition control module. The
car is currently out of warrenty (it gets driven A LOT--mostly on the
highway).



Please, please, please help me out. I've been scratching my head
since Sunday on this one. I am now afraid to take this car on any
trip longer than 30min.



Thank you so much in advance.



Mike

 

sounds like crank or a cam sensor. good-luck

 

Hey, it could be the gas cap...no I'm seriouse, if you screw it on all the way you make the gas tank air tight, so your fuel pump creats a vacume and your engine doesn't get any gas. as for the check engine light, I dunno,I would take it to a mechanic that you trust(not the dealership) and have them hook it up to find out what is wrong.Edited by: Sablefreak
