check engine light on

[autumn_again]

check engine light comes on, no flashing. it doesn't come on at start up.

comes on after driving for 10 minutes or so. just cruising in 5th gear.

And......................

What codes did you retrieve?

Mine does this same thing. well, sometimes its at 40 mph in 3rd, sometimes its 5th on the freeway, stays on for a couple seconds then goes away, happens every couple weeks. Didnt start until I put on the lightning bolt antenna, so I just figured it was that. I have a code checker at work, and I've got a procrastination issue, so someday I'll check it.

i dont have an obd1 scanner

normally i would count the times it flashes and then look it up, but it doesn't flash it will randomly come on, stay on for a couple seconds, and then just go out.

All you need to pull codes is a paperclip or jumper wire.

 

[autumn_again]

i dont want to erase it though. i want to know what it is.
it came on for a reason.

just not sure what the problem is, i don't want to find out its a problem that i shouldn't drive the car because it could cause more damage when its too late.


once i find out what the problem is, i'll clear the code.

a mustang with a check engine light on... theres a shocker LOL...

what do u have for an exhaust, it could be o2 sensors, no?

 

[autumn_again]

i have the stock headers, stock midpipe, and welded in flowmasters to the stock catback.

the cars got 205,000 miles on it, so i think the 02 sensors could definitely use a replacing, which i planned on doing when i bought my new headers and mid pipe.

It's probably EGR related, buy the scaner for less than $30 bucks and pull the codes.

paperclip? hows that work? might get my lazy butt out to the garage if I get to see a neat new trick, how do you do that?

try cleaning the MAF its easy ,cheap and can solve a lot of probs, thats what fixed mine. do you have a haynes manual or a chilton it says in them how to use the paper clip method to find codes. any body with an older vehicle has to have one of those books unless you have money falling out your back side

I've not mentioned clearning the codes once. I was the one who wanted you to retrieve them (rather than guessing at what the code might be). So why would I want you to only clear them?

AGAIN, you can retrieve the codes with a paperclip or jumperwire. Re-read your repair manual and pull the codes.
