non-camaro question

[Mike88]

hey I've got a 1997 Ford Escort as my beater for work and I just can't get the thing running nice...yeah i know its a Ford which might explain it. I guess I'll eventually bring it to the garage but I really try to do that as last resort. Anyway, I'm getting two codes, one says its running too rich, the other says its running too lean. I pulled the plugs out today and I've got white crud all over the plugs, which tells me that its running lean. I figure I get the too rich code because the computer tries to compensate for running too lean and overdoes it once in a while. Anyway, I'm likely going to check my oxygen sensor(s), but does anyone have any other ideas as to what might be causing this?

PS move this to 'other rides' if necessary.

Re: non-camaro question

My guess would be an O2 sensor or sensorS, depending on how many you have. A bad injector can also cause a problem like you described too.

Re: non-camaro question

all 4 plugs have white corrossion on them so its unlikely an injector problem.
