It should generate a DTC if the O2 sensor is at fault, but with 120,000 miles I'd think about buying a new sensor for general practice. The O2 sensor inputs to the PCM, the PCM determines rich or lean fuel ratio. If you are able to scan, look in the history files for codes like P0171 or P0172.

yea i was busy sorry, the injector circuit light isnt coming on anymore since i fixed that vacuum leak

car is still sputtering and stalling when i start it up i have changed the IAC valve,PCV valve, IAT sensor. i cannot figure this out..

Rich,

I have a scanner...although you are a little way out. It'* possible I could meet up with you and the Boston guys up your way.

i have no clue...

Here'* a link to a Techinfo article on checking coils.

Only the FRONT sensor in the DP will affect anything. It generally will not set a light until long after it'* toasted. Most O2'* start getting tired at about 60k miles.

How about we do a full tuneup on your car? PCV, fuel filter, air filter, O2 sensor (you did plugs and wires, what wires and plugs did you use?), and the like. Including pulling your TB and cleaning it per the procedure in Techinfo.

Diagnosing problems on a car that hasn't had a tuneup in that long is pointless.

i got the PCV, fuel filter, K&N air filter, new IAC, plugs and wires

i cant find silverbullets post about fuse blocks
