I got a 94 accord dx with a h22a swap and i keep getting. A check engine light after driving around for a bit so I checked the code and it was a code 12 something to do with the egr system can anyone tell me some problems that occur with that and how to fix it

 

is your egr even wired up?

 

9/10 times it's the egr valve being clogged. Clean it. Clear the code. Be on your way.
