Symptoms
Fuel Trims Climb and engine is running hotter

What are the trims and how are you testing them?
How's the coolant level?
Is it consuming any coolant?
Is the oil milky?
Is the water pump original?
How does the air filter look?
What brand O2 sensors have you used? Dodge trucks often have issues with aftermarket sensors. You might be chasing a red herring.
Did you switch gas stations about a month ago?

 

Sorry im just so tired and beat work 12hr days then try to work on the truck my days off keeps raining me in and gotta get this fixed i was gonna take the throttle body off but passed out wake up and its raining lol on trims max out at 32% after warming up and driving im testing with my launch scanner live data
no oil in coolant or vice versa water pump changed a lil over a year ago changed thermostat when started to get hot air filter is a few months old o2 sensors iv changed out nkg i think and some cheap ones now i think bosch on upstream and use the same gas station my coworker has same truck and has warranty on fuel pump and radiator and said i can use his warranty wanna make sure before wasting that but im stumped out of ideas and broke

 

Before wasting time on a fuel pump take your truck out for a drive with the fuel pressure gauge hooked up, if you can tuck it up through the hood. If the pressure is good don't even bother.

You can get a set of fuel injectors on Amazon for like $60 for the 4.7. A clogged or failing injector can cause a lean issue.

 

iv heard horror storys about those I ordered a set and returned them cause they just felt cheap i took all of the packs out and injecters cleaned them i did notice a few have a crack going down the side of them runs good until she warms up and start getting in the pedal then maxed fuel trims all of a sudden i dont know are those injectors ok

 

How did you clean them? Did you energize the coils while shooting pressurized carb clean through? I have this tool -> and it works good. Lets you pulse the injectors while spraying cleaner through.

 

i used a battery and spray can rig and a jewelry cleaner lots of crud came out she fired up ran perfect until i gunned it then all sensors i ges went crazy about 1 min into drive it appears i have a huge electrical problem im guessing iat sensor reading -40, o2 sensors max volt, map goes crazy, all at once and the same times by what im seeing here are some pictures as it wont let me post the recording it all seems to start when fuel loop opens so where should i look or is it a computer fried iv fixed some wiring issues and bank 2 seemed to drop a bit but im not good with electrical at all to time consuming














ing

 

Well funny i took all the wiring apart fuse box, computer and all grounds used contact cleaner brush and let dry inside as its been raining all day and went to start it and she runs fine so far no lean condition but battery charge while running is now 13.5-7 was running 14.3-5 everything seemed to be running good mpgs back at round 12 in town havent hit highway yet or try ac or radio dont wanna jinx it got work in the morning
