More Escort Issues

Have you done any work on it lately? How is the wiring harness that the O2 plugs into. Sounds like the new sensor made little difference. Being so old a car, even if the current O2 sensor was still functioning a NEW one would surely make some difference. I would definatly check the sensor wiring.

i just went and pulled the vacuum line off the FPR and it is dry. Ill try to get a pressure gauge on it tomorrow during lunch. I would love for it to be as simple as a bad FPR.

may not be wet, does it smell like fuel if you get up close and all personal like with it? engine off of course.

the old O2 sensor wasnt in that bad of shape really, i replaced it more for peace of mind. the harness going to it seems to be solid and the plug is clean and dry.

getting up close and personal with this fuel regulator isnt an option. access requires removing the upper intake

i tested fuel pressure today and it was within specs. i also checked the CANP solenoid harness and i get 12v with the key on.

i should see if i can use the shops STAR tester on one of my days off. maybe the datalog will reveal something quarky.

Try the cheap stuff first!

I have dealt with this same code at least 5 times.
It struck me as odd that 2 of them I used a cheap injector cleaner on and they fixed right up...no more codes and still run today.
The 3 others got a treatment of Seafoam in the tank and the fuel pump died before the tank was done.
The only other thing was a fuel filter replacement on all 5.
It may be coincidence, but I tend to keep away from Seafoam.

P.S. I did the O2 on 2 of them.....don't think it was the problem.

thanks for the info egnorant. ive always had good luck with seafoam and ive been meaning to run some through this car (in hopes of smoothing out the little roughness i mentioned) but i keep forgetting to pick some up. ill make sure to get some tomorrow thought if theres a chance it'll help keep these codes from coming back. i might even run some cheap stuff in there too..just to see what happends
