Maintenance/Repairs

I have a 2016 Jeep compass with 122,000 miles on it. About a month ago I used my remote start one morning and it revved up really high and sat there for a little and RPMs started fluctuating really bad and my check engine light came on along with the electronic throttle control light and traction control light. I read the code and it was p2173 (vacuum leak, high air flow, slow accumulation). I took off the throttle body which is all electronic but I cleaned it real good with carb cleaner cause it was filthy and I put it back on cleared the code and nothing else happened for a month. After that month it happened again with the same code and RPMs were fluctuating and settled down at 1,500 RPMs which they normally settle down to 800-900 RPMs and it went into limp mode all the way back home. The next day I started it and the warning lights were still on but it was running normally so I cleared the code and decided to take it to work to see what would happen. Went to lunch and it all started again. I have no cracks in my hoses and after research it says it could be the intake manifold gasket or a sensor or the throttle body which I cleaned and it was in good condition. Should I check the manifold gasket or could it really be a sensor
