Hey Scotty!
My 2007 Toyota Camry 136k miles has a problem two cylinders are not working tried changing the spark plugs coils and valve gasket but still the same very has a high fuel consumption what are thoughts please help!!!!!
what do you suggest ???
it has some weird noises in the engine tried cleaning the fuel injector but still same
Hisham did you check the compression? if yes what's the reading? did you verify that there's fuel reaching the cylinder and there's a spark?
Around 55-60 psi !
Yes there is fuel reaching
That compression is obviously way too low. Squirt some oil into the spark plug hole and recheck. If compression improves it's a problem with rings, if not you probably have a burned valve or head gasket is leaking on that cylinder. You could also do a leakdown test and check for where air is coming out.
Please see the misfire topic in the FAQ
