2010 mustang gt manual (cam, tune and cold air intake) goes in to limp mode after 5 mph then code p0102 . i have replaced maf, tested all fuses and swap engine harness.(maf counts sometimes gets high and shuts off the engine) what's next ?
Make sure everything in the CAI assembly from the air filter to the throttle body is secured properly and air tight. You might also want to check that the MAF sensor itself seals properly against the CAI pipe.
