Hey all i have a question about Fuel Injectors. I figuered i would try to clean my fuel injectors to see if it helped run my truck any better. Firstly i cant find the schrader valve. Secondly I was wodnering how i would go abour cleaning them, i figuered i would take them out and apply a 12v power source to them and then run some injector cleaner through them. However i read in my chilton manual someplace(cant find it again) to never apply direct power to the injector?? Any ideas? Also I previously posted my engien codes but wasnt sure if i read them correctly, if anyone wants to confirm that i did, heres a link.
