Weird Fuel trims

Creative-Business202B to Mechanic Advice@gearhead.townEnglish · 10 months ago

So I have a 2010 Ctown Victoria that’s stumbling. So far I have replaced the MAS, O2 passenger side, passenger side all 4 fuel injectors, EGR valve, & fuel rail pressure valve.

However is still says Fuel system 2 Cl_fualt And my Fuel trim for bank 3 & 4 both still say -100%

But I also don’t have a check engine light yet.

Rules

This is a community for asking Mechanical questions pertaining to vehicles, engines, etc. If it’s got wheels, treads, floats, flies, or has an engine you’re good to go and we’ll do our best to help. Title, salvage, body work, paint work, etc questions also do not belong here. Memes, videos and other non-questions are not allowed.
No intentionally bad, harmful, or deceptive advice. If we feel a piece of advice is particularly reckless, dangerous, or extremely unhelpful it may be removed. Please report bad advice to the mods.
Keep discussion friendly, civil, courteous, and professional. We’re here to help so being rude won’t help. Don’t assume a shop is trying to “rip you off.” It’s okay to ask for a second opinion.
Only one vehicle/problem/incident per thread, and only post once. The only exception is for posting updates, provided it is properly marked as an [Update] or similar.
Body Work. Questions related to dings, dents, accidents, paint and so forth DO NOT belong here. Take the car to an auto body repair shop who can give you a qualified estimate.
