Emissions Leak help
So I'm driving to work and about half way the 'Check Engine' lite comes on, now I'm a little shocked so I turn down the radio and listen to my truck. I can't tell any diffirance, no whines, pops, clicks, lagging or hesitation. The only thing I can think is low oil pressure (since FORD didn't equip an oil pressure gauge) so I kept my eye on the temp it stayed right where it is supposed to be. When I get to work I quick check the oil level and it's perfect. After work I go to Autozone to get the codes read and both codes taht came up were 'EMS System Leak LARGE'. Now according to my trucks brain I have a leak in my Emission control system,I'm assuming it is probably a vacum hose that has been dislogged.
How do I check for the leak?
Aside from the O2 and MAF sensors, what other equiptment connections do I need to check? (O2/Maf would have affected preformance, performance still A+)
I already removed n replaced the gas cap (It has it's own idiot lite but I checked it any way).
Thanx for any and all assistance and suggestions.
