my 5.0 is only runnin on 6...

My 5.0 SEFI is running on 6 cylinders. It is getting fire to all plugs and it has good compression. I'm not familiar with ford motors so i need help. I think there is a problem with the injectors, but is there anything else that it could be??? THANX

How did you come to the conclusion that you are only running on six? Give me more info on what all you have diagnosed.

When i started it up, i could tell it was not hitting on all 8.. but i put a test light on it to figure out which cylinder it was... it turned out to be 2... #3 and #7 are both dead.... they ARE getting fire tho.. and they DO have good compression. If it is not the injectors, what else could it be?!!?!? THANX

Have you checked for codes. It should tell you if you have an injector out or 2.
