Intake issues

[InfamousDragon]

So I'm a lil old school when fixing imports and this yaris is new to me so help me out if you would people. I put together my own intake with a very large filter haha. Anyway here are the problems I'm running into. The intake goes from the lil 2 inch port to a 3 inch maybe 3 1/2 inch filter. It's a big filter for the car I know but I want it to get plenty of air and stay nice and cool. 4 cylinders get super hot if you don't know. Anyway I did the install properly I know that for a fact but I still get the check engine light and when I drive the car the throttle does not respond its like its bogging out. Well it just started doing that after I fixed the intake connections but before I fixed it it was running fine now well I should have taken a break while working. So I need to know how to reset the check engine and the ECU on this crazy lil car. Lil help for an old school from you new school
