injector sticking?
 

So Friday or Saturday, I can't remember..."Memorial Day Weekend", I swapped from stock injectors to 460's. Yesterday I pushed the car out of the garage to work on my new garage door opener, later on I started the car and drove it into the garage and when I shut it off I smelled gas. I popped the hood to find one injector misting fuel from where it meets the rail. This happened once before when I swapped injectors. I pulled the rail today to find (of course) a torn o-ring. I replaced it and put everything back together and started the car. It idled for a while then there was a louder than injector ticking "click" sound. Then the car sounded like it was running on 3 cylinders and it ran rich, like 12:1 idling. I tapped the gas pedal and then it ran normal. Think an injector was sticking open? What possibly was the click noise? I ran those injectors last year and they have been sitting in a bag on my work bench until like 5 days ago.

injectors go bad when they sit unused. Mine was cleaned and never used for 1.5 years and 1 of them was stuck closed.

Oh that's great. It got me to work with no issues today though. I hope it loosened up and doesn't happen again.

You can also crimp and injector wire and do the same thing. You might just check to make sure it is free of problems.
