Old/worn O2 sensor?
no i put a brand new fuel filter on because i had to install the tbi fuel adapter to it so i just replace it at the same time.no exchaust leaks as i know of and i replaced all vac line and o2 sensor is 1 month old.ive been trying to fix this lean code for a long time know and replaced alot of parts.i think im going to buy the tbi repair kit and replace all the tbi gaskets in case its leaking and it comes with a fuel pressure diaphragm so i can rule that out to.
