Hey guys. I finally uploaded my video on YouTube and will list the link here for you. Been having issues with throttle body which makes some weird noises after i drive the car for a while and then shut it off. I also get the p0638 code every month or every other month. I already checked the H42 connector, several times, and wiring. I replaced the throttle body with another used one and it makes the same noise. Could I have just gotten another bad throttle body? Have rough idle and sluggish/surging accelration at half throttle. Sometimes accleration is fine other times it's not. Also, when cold the throttle body does not make any noise. Only after driving for a little bit.
