Sorry to bring this post back to life, but I've been having a P0128 (Thermostat Rationality) code that keeps coming back so it's going in on Tuesday. Is this part of the issues many other members are having with their I4? Some times at startup as I've stated in previous posts, it shutters really bad and the RPM's seem to jump from the low end to as high as 1200rpm's . After about 30sec it'll level off but if I even attempt to put it in gear it almost feels as if it's going to stall out .
