I was wondering if any car guys could give me a couple pointers here. I dropped a new motor in this car awhile ago and put about 1000 miles on it since with no issue.
Yesterday an issue popped up. After it cooled off and I started it again the RPMs started off normal then climbed up to 2k and hovered there for a bit then it started running terrible until I gave it has. I shut it off and had a roommate start the car while the airbox was open then as soon as the rough running started I clicked the airbox back together and the problem went away until it cooled off and was started again today. I know to clean the mass airflow and throttle body but if that doesn’t fix it where would I look next?
