Hey guys. My name is Luke it’s my first post on the forums. I’ve searched and searched for a solution to the issues I’ve been having and I’m getting nowhere. I’ll start at the beginning. About 5 months ago I purchased a stock 2015 Mustang Ecoboost. I first modded with a pypes 3 inch downpipe as well as a tune to support that. I took a road trip and soon after I arrived I got a check engine light for misfire cylinder 3 and misfire startup first 1000 revolutions. Car functioned fine but was still concerned. When I arrived home I changed the plugs with NGK one step colder and I’ve since played with gaps and had no luck. I’ve changed coil packs, PCV valve, and checked for any vacuum leaks or loose connections. I added a K&N intake to compensate for the lessened backpressure with the exhaust as well as an oil catch can to catch whatever was messing with the engine. Nothing resolved the issue. The car sputters slightly at a stop and rpms vary about 800-1700 just sitting. Driving everything was alright except I lack the torque I know the engine has. My friend and I compression tested it and found that cylinder 2 and 3 weren’t to par. We did a headgaket replacement with ARP head studs and she started back up. However, after doing so the car still throws the code. Not nearly as often, but occasionally cylinder 3 misfire and startup first 1000 revolutions. Now present day... I continue to get P04DB and P0234 causing my turbo to go into limp mode with ANY hard acceleration. I have a SCT tuner and have been in contact with the Bama team doing revision after revision and getting no solution. I still get the codes running stock. I notice that when stopped the air fuel ratio also jumps with the rpms. I’m fairly sure it’s a sensor. All my lines are good and connected double, tripple, quadruple checked. Could this be a MAP sensor or boost sensor? I’m stuck and I know she doesn’t drive correct. My girlfriend has a 2016 Ecoboost and my car no where near torques even close to hers. I also get a lot of turbo flutter as opposed to blow off but again I’m stuck in the dark. Thank you for reading my essay of a post and for any help you can give. Sucks having a brand new car with good parts that hasn’t performed properly since I bought it. Thank you.
