In the process of doing stand pipes and dummy plugs. While the valve covers are off and have access to the rail, is there a way to determine which of my injectors have been acting up (sluggish performance when cold) without putting it all back together and running the motor?
Thanks, Mike

 

Not really no. You could pull them all and send them out for testing. Best way is with a scanner and cold start watching the contrib test. It will tell you in seconds.
