Renix fuel injector question
About a year ago I replaced all six of the fuel injectors on my 88 cherokee. Latley I have been having problems starting it and today I noticed that I can move/rotate all injectors with my fingers. Is this normal??? There is no gas leaking and when I swapd everything I used new o-rings. Also after I tweak a few of the injectors the Jeep starts right up. Could this also be the cuase of my 9- 10 mpg?

They will move a little but shouldn't be really loose. If too loose, it will suck air past the o rings. Causing higher idle and/or poor mileage.
