yeha thats what i dun 1 at a time first 2 killed the engine 3rd jsut dropped revs very slightly and 4th killed it aswell.
dont the test with the injectors that all have the same squirt pattern and are not bloked.
and had a diagnostics on it and said i believe clyinder 4 or somthing.
would the throttle body have anything to do with the problem?
