2 or 3 digit codes?
I just bought a code reader because my check engine light has been on and off for a while. Do we run 2 or 3 digit codes, the Ford manual says nothing about this. I am pretty sure the digits came in pairs of three, and I threw these codes.
#172; Heated Exhaust Gas Oxygen (HEGO) sensor - voltage signal indicates "lean" (Bank #1).
#136; Heated Exhaust Gas Oxygen (HEGO) sensor - voltage signal not switching during Engine-Run Self Test. Indicates "lean" (Bank #2)
Can someone confirm that my car runs 3 digit codes before I investigate this problem. I guess I will check for vaccum leaks and then check for problems along my fuel lines.

RE: 2 or 3 digit codes?
It is a 3 digit code. You may have some bad O2 sensors that will need replacing... unless you really are running lean. But that's easy to check as well. And if everything seems fine and it's just tossing codes, then try replacing the sensors. It's fairly common for bad sensors to give those codes. But it is not quite as common to have it hit both banks at the same time.

Well bad sensors wouldn't affect driveability would they? Because my car is still bucking around a lot during acceleration. I should have mentioned that above I guess. Accelerating and even taking off from a stop have been very rough and shaky lately.

there are a lot fo ways to seeif you are really running lean. But personally I just go out and pull a few spark plugs and examine them. They are usually good indicators of how everything is running.

Yea I am going to change my plugs in a few days and I can will check the condition of the old plugs. I will check my pump, filter and injectors and clean/replace them depending on what I see. This problem has been occuring since I first owned the car, only now its got worse. I can't wait to have a smooth running car, and doing the above should do the job. Thanks for the help samseed

I wouldnt go an spend money on sensors right way , like recomended check you filter , IAC, Plugs , MAF , and do a presure test aswell thes are cheap and quick things that might save you a few buck and a good way to learn proper dianostics skill

where can i get a code reader? about how much do they cost? last but not least where do i plug it in on a 93 notch?
