Every so often, after driving ~15 miles to school, on the way home the check engine light would come on. But soon after it was lit, would be off again. I can never get it to the mechanics while the light is on. Any ideas? Nothings is noticably wrong with it.
BTW, I'm replacing the air filter and spark plugs very soon (w/in the next week), hopefully it solves the problem. I'm also looking for some ignition wires if any one has any ford racing or magnacore sets avaliable. PM me if you do.
Thanks.
have you taken it somewhere to pull any codes that might possible be in there....kinda sounds like a loose wire or connection somewhere
Sounds like Misfireing to me..when was the last time you changed the plugs and wires.
Since you have a 95, you can pull the codes yourself with nothing more than a paperclip and a set of instructions. Directions should be in the main site's FAQs or at
www.fordfuelinjection.comThe light does not have to be on. The computer will store the code and maintain it for a minimum of 40 drive cycles for retrieval unless the computer is reset.
Attempting to diagnose the problem without the code(s) is about as effective as farting into the wind. Get the code(s).

i highly doubt a mis-fire. a mis-fire would more than likely be noticable as far as drivability is concerned and the light should be blinking off and on right in a row (on one second, off one second, on one second, off one second.....) i would place my money on an emissions sensor or something along those lines. just my opinion though. should def change the plugs and wires though just for preventitive maint.
I did that self test and I worked perfectly!
The codes I got are: 33, 55, 19, 33, 55, 19, 33, 23, 36, 33, 23, 36.
Some of the codes that I looked up didn't make since or I didn't know the term. But as soon as my air filter arrives, I'm changing the plugs. The wires will have to wait cause I want either Ford Racing or a Magnecor set. Hopefully it will solve the problem but from the codes, it doesn't look like it.
just a heads up from what ive seen, you will wanna do wires soon. with it being a 95 and all, with you taking the wires off and disrupting them, you might run into an engine miss. they just get brittle. i would say anticipate them needing replacement in the near future.
Get the ford racing ones, they are cheaper and just as good.
ive had the same problem and it was one of my sparkplugs misfirinf, i recommend platinum boshe or how ever you spell it. they last long and good in cold weather. good luck
Misfire.
Ford Racing wires.
Mine did that when I had my misfires. Turns out water got down in the sparkplug wells when I washed the engine. New plugs and new wires should do the trick.
You should have gotten 3 digit codes....
Recheck...

Ford wires were not proven to misfire on the Zetec..only the duratec and thats not all of them.
