1. There is NO SCREEN.
2. Did the 'Check Engine' Light come ON? Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on.
You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE the problem and perhaps eventually fix the problem.

Vacuum lines do not get plugged up. They get hard and brittle with age, that causes them to leak through the cracks and at the ends. So if your lines are 10 years old and have a 100k on them, replace them. Most are just two ID sizes, and you can buy it by the yard at parts stores. Replace them one at a time to avoid the common screw up of putting them on wrong. Does not hurt to use the cell phone camera to take "before" pictures just in case. That is the cheap way to eliminate one possible problem. After that replace the dealer suggested parts one at a time starting with the cheapest first. Most of those parts can be had at parts stores way cheaper than at dealer.

You may have a vacuum leak or a hose that came loose.
