Its unfortunate the sensors didn't fix the issue, was there signs of metallic build up on the sensor? That was actually my first suggestion, but at the price point replacing wasn't necessarily a bad idea.

What brand of FCA did you use? I can't remember did you get a tool to read live sensor readings? I would also be curious to monitor, Ambient Intake Temp, Intake Temp and coolant temp. I would get a baseline reading on a cold sunk motor, left for several days if possible but at minimum overnight/12+ hours so they are all reading close to actual ambient

 

The oil pressure sensor wouldn't cause anything like this would it? Just odd there's oil on the thing, and no no metal on it if any might have been very very little, and absolutely I work and drive the car most days during the week so Friday I'll get u that reading, anything else you would suggest while I'm at it?

Have you ohm tested all the injectors?

 

No sir I have not could u explain how to ohm test them? I don't have a good ohm reader just a Chinese cheapo

 

Well I just went ahead and ordered a decent one and will definitely ohm test them injectors this weekend

 

Ill have to check the pin outs, or you can, fortunately you have an early motor so the harness is split into 3 banks, 2 injectors to each plug. I can't give you readings because good injectors can vary, the biggest thing is that they are all close together in readings

 

What do u mean check the pin out?

 

Slang I guess, it means viewing a wire schematic and it will tell you which pins of a connector go to what electrical components, injectors in this case are control by a solenoid. This solenoid is is controlled by the ecm, You will see just above the fuel lines in the side of the head, there will be 3 grey, square connectors, each one contains 4 pins, 2 of which each go the an individual injector. The pinout will tell you which two pins to measure for each injector. I solenoid is just a magnetic coil, generally speaking these injectors should be 10-20ohm if i recall correctly, however, just because they are outside this range does not mean they are faulty, if they all measure similar, within 3-4ohms, I would not be concerned at all. Again being as the issue happens on a cold motor and goes away when warm, we would want to test when the motor is cold.

 

Oh okay makes sense I will get it checked out absolutely, I'm starting to believe it has to be an injector issue, truck runs fine when warm I would just rather find the issue before something negative happens
