I just got done putting a rebuilt head on my 22re. It was milled and had new valves put in. I also replaces the timing chain while I was there. I got it running and adjusted the valves after it warmed up. There is still a ticking noise that sounds similar to loose valves. When I drive it runs fine until half throttle, then it starts to bog down. After driving it a while it started to get hot. Does this sound like an injector issue? Any help would be greatly appreciated.

 

Sounds like a timing issue.

Have you changed the fuel filter as of late.:jessica:

 

I will check the timing again. I replaced the fuel filter less than 200 miles ago. thanks for the help
