AU Contraire MON Ami....if the EHA is leaking, it needs replacing....period. If the c/o % is very low after setting ratio/on-off values to 45 to 50 % then the EHA ratio needs adjusting as per my link above.
If ever you adjust the Allen screw in back of the EHA, then yes...be very careful not to lose the original setting as the Allen is quiet loose and easy to turn.
The EHA is everything to smooth engine running, starting, acceleration. ...providing upper to lower pressure is correct.
Cap and rotor are usual suspects, I agree.
