IPD Plenum+75mm TB +Intake=CEL and spuddering
I installed the IPD Plenum with its silicone hoses and the larger 75mm Cayman 3.4L throttle body which is needed to make the plenum work. I also installed an intake but changed out its oiled filter with a dry cone filter from Ingen.
I had to break the factory airbox to install the intake. After checking all the hoses for the plenum and throttle body I started the car can the engine was spuddering. NO CEL. I was told that the computer would adapt to it after some driving so i drove it a little and got a CEL after 6miles. The engine was still spuddering sounding like an air cooled porsche or a muscle car. I tried everything to look for a leak or re tighten the hoses. The engine still spudders. I reset the computer and I still get a CEL after a few miles. I ran a diagnostic and got MAF, misfire in cylinder 4 and 6.
any idea what this is? Im thinking just changing the Mass Air Flow sensor. But mine was not touched or damaged so i dont know whats wrong.
what do you guys think?
