Hey guys I am hoping somebody might have a solution. I have an 07.5 d max. About 5 years ago i deleted the dpf installed an AFE intake and installed a small single milage tune from atp. Everything was great until about a year ago after i cleaned the air filter(dry) On hot days after coming of the highway to a stop, i get the p0101 and reduced engine power. Only after coming from a long drive on the highway and the first stop. I can clear it and then its fine. Last year i did try replacing the maf sensor and recently installed an egr blocker plate. I have also replaced the hump hoses on the intake. I am at a loss as to what is causing this. It doesn't do it in the winter. Will putting my stock air filter housing and filter back in work ok with the tune? This all started after i cleaned my filter. Thanks for any and all help.
