DRAMIT

I’ve been running regular gas for over a month now. Treated with Lucas 2 times. Fuel consumption is still up and the idle like I said is still a little shaky. All other aspects it runs fine. Is there a way to test the ECM to verify it’s the problem?

This is the second time the coils have been replaced in the 2.5 years I’ve owned it. I assumed it was cheap coils. Went with all molar parts this time. Also she has always run E85 in it. Not sure if that makes a difference but the injectors were gummed up pretty good. Codes are P2099 P0300 P0302. My scanner also shows the P0300 and P0302 as permanent codes?

Hopefully you guys can help I’m at an end pass. I have a 2018 Dodge Journey 3.6 with 54,000 miles. I keep getting a cylinder 2 misfire multiple cylinder misfire and O2 lean bank 2. I’ve replaced the coils, plugs and fuel injectors. I also had to replace a leaking valve cover gasket and I still have the same problem. The light will go off for a couple days and come right back with the same codes. It idles rough with no load in the engine but that has gotten better since I replaced the injectors. I’ve checked for a vacuum leak and everything there is good to go. Not sure why I can’t find a problem! Any help you can give us appreciated. Thanks in advance!
