check your oil.

 

pour som robitesum in with the oil

 

Has your tach always jumped to 11000 when it hits 4700 or did it just start doing that when you started feeling the power loss?

 

tune up time....

 

its a cheap tach its probably going out!i think my injectors are fucked.....cause when i put gas everytime i have to pump the gas pedal a couple times in order for it to start....

 

fuel pressure regulator..

 

tach problem is probably your wireing...

 

Give it to me

 

thanks for the reply its the msd output for the tach its all messed up
