Direct injector install question
 

How much force is required? I've had them in the freezer. Put a little oil in the tube and on the injector tip. I've pushed reasonably hard with finger pressure. The injectors were professionally serviced with new seals installed. Any thoughts?

That sounds about the same force as i did. But hey im the one who has his engine running lean.

Hopefully others who have installed these can chime in.

For better or worse, they're in. 2 made the "potato gun" sound and the other 2 slowly sled in as I tightened to rail bolts. There wasn't much resistance. I guess there is no way of knowing if things are good until I crank it up tomorrow. Thanks again.

I guess it worked
 

Initial fire up went well. Had a friend over to check for leaks while I held rpms at 2500. No leaks nor unusual noises. Had a p0198 cel. Guess who didn't have a sensor plugged in until it clicked. I need to learn how to datalog to make sure everything is ok.
