i have a slight hesitancy when i get to about 2000rpm(as in a misfire)...ive done my plugs and leads now im wondering if its the big block thing on the end of the engine ......is that the coilpack!!!...where the spark plugs come from??? ...i have a x14sz engine ..cheers for the help ...!!!!

Follow the spark plug leads away from the spark plugs and they should be connected to the coil pack.
