2kstang · November 15th, 2009, 05:07 PM

Hey guys im new to the mustang world. i just bought my first 2000 ford mustang gt. So far I have a jlt intake, x pipes without cats, and flowmasters. My problem is that when i first bought the car with all the upgrades it did 160 miles before going on empty now ive noticed it did 210 miles before going on empty and also the check engine flashes? if you guys can help me out here that would be great

If the CEL is flashing, download the codes. If you're too broke to buy an OBD2 Scanner (less than $100), go to autozone, most will scan the codes for free.

Regarding the mileage, has your driving changed? Most people wouldn't complain about their gas mileage increasing, hahaha.

A flashing CEL means the computer has picked up a misfire. You're going to want to stop driving it until you figure out the issue.

2kstang · November 15th, 2009, 05:41 PM

would a sct or predator programmer fix that problem?

C MY 4D · November 15th, 2009, 05:49 PM

You could read the code with it but no it won't solve your issue.

Thumbie · November 16th, 2009, 12:32 AM

does that mean there is a missfire, nothing else? well the lack of cats, unless it had mil eliminator's would throw a code. and there could be a number of things leading to misfire, goodluck with that

+1, anytime the CEL blinks it means that there was either a misfire or multiple misfires and you need to get them checked out ASAP

If the CEL is flashing, stop driving the car asap! I forgot where I read it, but it means one of your cylinders is misfiring. Don't drive the car until you get it fixed!

[EDIT]

Looks like I was beaten to the punch.

i went to autozone and found that the computer was reading that there was a misfire on cylinder #5. went and removed the spark plug cable and found that there was water inside were the spark plug sits. i dried all the water with a blow dryer and car runs better than ever .....never again cleaning the engine with "engine cleaner" and water.thanks guys for all the help

C MY 4D · November 16th, 2009, 07:37 PM

No problem....

DiZzyBonne · November 16th, 2009, 08:20 PM

Just curious, how long have you been running the engine like that?

2kstang · November 16th, 2009, 10:12 PM

i say about 2 weeks

Ksmith7548 · November 19th, 2009, 11:30 PM

ya dude dont worry bout it, my car does the same fucking thing, ran a brand new engine while it was misfiring for like 3 weeks, no damage done. I had the same problem, power washed the engine and got water down the holes, i also have a bad fuel pump which makes it misfire sometimes
