So the other day my jeep starting doing the "laughing monkey" noise. I found out it was the OPDA .I never done it before but because I'm a broke college student I do most of my work myself. Anyway, I watched multiple videos on YouTube on how to install a new one. I installed it just like in the videos, and I turned it on and I got a check engine light with a code P0334 and it was actually running better than it was running at idle. So I let it run for about 30 minutes at idle. Then I took it on a test drive everything til I hit around 2,500 rpms then it started bucking badly luckily I was only 500 feet from my house when it started. I don't understand on what I did wrong? And is there a chance that I could've cause a lot of damage to my engine?
