Going to look at a 2001 GT Vert tomorrow.
I gave up on my foxbody dreams. (can't find anything worthy of being a DD)

I know what to look for as far as appearance, engine, tranny, leaking fluids.

The guy has an offroad bbk x pipe and flowmasters for exhaust, but says there is a check engine light that came on when he got the offroad x pipe installed.

Does this sound right??? What would I need to do to get rid of it??

Probably doesn't have cats due to the o/r pipe a tuner will turn off the check engine light but I would run it by autozone have them scan for codes and see what else there is just to make sure the check engine light is only on for the o/r pipe

look into "spark plug non foulers" for the rear 02 sensors if you need a cheap alternative to buying a tuner. otherwise, a tuner will get rid of it and disregard rear 02 sensors. the non foulers will trick the 02 sensors into getting the reading it wants.

He may be missing all cats since its an o/r pipe check if it has any cats left but yes anti foulers is a cheap alternative

I had the same issue when I installed my off-road x. Got myself a bama tuner from am and the lights gone for good. Also found that you could clear it with an obd 2 scanner for a couple hours if needed

Regarding the CEL issue:


1- yes an offroad x or H pipe will throw a post-cat O2 sensor code 10/10 times


2- You can get rid of the code with a Tune or by tricking the ECU into thinking it is getting the signal it wants from those rear O2 sensors.




What those rear O2 sensors do is monitor the health of your cat converters. O/R x and H pipes don't have cats, so your ECU wont be getting the go-ahead from those sensors anymore.


Those sensors do not have a say in what AFR your engine runs. That is the job of the other O2 sensors. All these do is monitor cat health. You don't give a **** about cat health. You only have to "simulate" that voltage signal from the O2 sensor to keep the ECU happy. Lie to your ECU with these: SVE Mustang MIL Eliminators (O2 Sensor Simulators) (96-04) CEL will leave. Also, you can make those simulators for $3 if you are competent with electronics at all.

This is good advice.. I done the same exact thing when I test drove my car because he said the check engine light was do to it not having cats.. Ran it by autozone and they confirmed that was the cause for it being on.. I would defiantly recommended a tuner though or something to get rid of that light because you will never know when you do have a problem cause that light will always be on..

Sounds right. No cats will cause the CEL to come on. Is the car auto or 5 speed? Check the tranny fluid and make sure there's no grinding if 5 speed.

It's a good excuse to get a tune, since it's off road everyone's right there probably isn't cats so just get a tune and have the tuner shut off the cats, I have my cats and EGR deleted and my MPT tune took care of my lights

Yeah he said it has no cats.
He also suggested taking it to autozone to prove that it was just the cats causing the CEL.

If I have a sct sf3 or whatever it's called for my 2012 v6, will it work for this 2001 gt?

If you return your car back to stick it will unlock your tuner

Oh dang, that's not going to happen.
Guess I'll need a seperate tuner for this Stang.

Makes sense though, so you can't just tune all your buddies cars for free.

So I went and looked at a 2001 coupe and everything was good for the most part.
Only thing wrong was a front end squeak/grunt when you turned the wheel.
What is that???

Thats what I was thinking. Sounded just like a 96 grand marquis that a lady I work with has. Made the same noise.

He's asking too much but only 108k miles.

Body is straight but paint is pretty ugly

I had a 96 grand marquis and I know EXACTLY what you're talking about haha. Mine was always there, but it never got worse. I even got that car airborne accidently and it never got worse. I tell you what, grand marquis is a handful when it lands from a jump. Yes siree
