miss fires ever time for the last 4months and I am afraid to spray on it. Could it be anything besides the opti? Some bolt backing out of the opti or something is was I have came to think it is. What do you think?

 

check your coil, plugs, plugwires, but at a high RPM, im going to point my finger towards the opti

 

Yeah its just so consistent, opti is prob right
