Engine code...

[Bluecrew07]

So engine light came on in the mustang... code is p0172 & p0175 sys too rich 1 2... other than that i donno what it is.. i can smell gas and can watch the gas gauge drop..

[bobtsgt]

means the 02s are picking up a rich condition in both banks. computer is giving the motor more gas. could be a couple of things. check all your electric and vacuum connections. may need to clean the MAF while your at it.

and if that doesnt work?

[bobtsgt]

sell the car to me for a grand :D

[Bluecrew07]

Dont think that gonna happen bob lol you have enough toys hahaha everything seems to be in good working order and clean ish lol

when ever mine threw the codes like that, they eventually threw circuit codes as well. My o2's where bad.

[Bluecrew07]

My o2's are still somewhat new

How long have you drove the car with the engine light on? The reason is because you want the car to go through a few drive cycles to determine that you are getting all the codes. Also, when is the last time that you changed the plugs? If there not burning off all the fuel it can also do this.

There are alot of different things that can make your car run rich. You can have a vacuum leak, bad throttle pos sensor, your mass air needs cleaned, and idle air tempeture sensor to start.

Maybe drove for about a week now..i changed the plugs last year but the car has sat for a year only been driving it for a month or 2 idle air is also new and cleaned mass air the other day

Are you running O2 extensions on your car? That maybe a cause of this issue I have run into that a few times.

[Bluecrew07]

Nope. i dont kow what the deal is but it drinking gas like crazy!

yeah if you can get a hold of a scanner check the temp sensor if its showing coldlike in the negatives got a bad sensor makes the compy think its cold out which in return makes dump more fuel

Did you drain the gas after it sat? If you didn't it probably screwed up your o2's. Same thing happened to me after mine sat. Replaced the O2's and everything was good.

[Bluecrew07]

no i didnt drain the gas.. it sat for a year but i started it up and let it run like every other day

[02mingryGT]

You'll need new o2's then. Old gas will destroy them.

[Bluecrew07]

ill try that then
