New to the group and it looks like you guys know your stuff. I have a 03 MM that has trouble starting but starts. Then it sputters as i press the gas but is okay pass a certain idle. I have replaced the IAC, cleaned the throttle body, cleaned MAF, new filter. Then when i hooked up my obd2 the temperature gauge reads 116 on a 34 degree morning while the gauge on the dash reads low. And when the dash temps reads normal the tablet says 233. Whats going on, any idea what to do?
