Attinne,

(You said) spark plugs wires preplaced

OK, well it's good that you replaced the wires, but have the "Spark Plugs" BEEN REPLACED AS WELL???

(You said) we have no intake or vaccume leaks

OK, so post in DETAIL the "Tools You Used" and the "Test's You Did" TO CONCLUDE that there are "No Vacuum Leaks!!!

ALSO:

Posting the results of a "Compression Test" (and) a "Cylinder Leak Down Test" would REALLY HELP "Your Issue"!!!

GOD BLESS THE UNITED STATES MARINE CORPS!!!
