The stuck injector would explain the shitty gas mileage and power loss, but wouldn't the check engine light come on if an injector was screwin up? Also, I find it weird that dumping 2 fuel injector cleaners seem to (in most part) take care of the problem temporarily
How do I check the injectors? If I take them off and inspect them would it be obvious if 1 was messed up? Or do you just check each 1 to see if it sprays right
