I CALLED A DEALER TO GET A GOOD ANSWER. ONE OF THE MECHANICS WHO HAS DONE QUITE A FEW VENTURE TUNE-UPS. HE SAID THAT HIS BEST METHOD FOR HIM WAS TO REMOVE THE COIL PACK FOR ACCESS TO THE PLUGS. HE ALSO SAIDS THAT THERE MANUAL STATES THE BEST WAY IS TO ROTATE THE ENGINE FORWARD. BY DISCONNECTING TO DOGBONE MOUNTS ON THE FRONT OF THE ENGINE AND PULL THE ENGINE FORWARD. NOTE: VERY IMPORTANT POINT USE ONLY ORIGINAL EQUIPMENT PLUGS AND AND DO NOT REPLACE WIRES WITH CHEAP MADE WIRES. NOT DOING THESE TWO THINGS CAN CAUSE MISFIRE PROBLEMS AND OTHER POOR PERFORMANCE PROBLEMS
