I'm getting low engine temps, so low that tech 2 won't even start the diagnosis. The mechanic suspects it's caused by faulty injectors due to rough idle too. They can't repair them so may have to replace.
The injector sleeve O-ring is available here and can be changed if damaged when removing injector.
Thank you!
