Engne doesn't run smooth

My engine does not run smooth. I don't have a vacumn leak. In my effort to track down the problem I grabbed my timing light and had a look at the ignition wires.

All the wires on the drivers side seemed good. flash.flash.flash.flash.flash.
But the passenger sides were not as smooth kind of like, flash.flash...flash..flash.flash..flash.flash.

Since there are only three coil packs firing two cylinders at a time this doesn't make sense to me.

Any thoughts?

Thew plugs were in excellent shape when I put the engine in. The wires are from aurora (www.auroraelectronics.com) and are also in great shape. I did however replace one of them with a Bosch wire (Came off the new engine) and had the same results. So I don't think it' plugs and wires.

SWAG, dirty MAF, or old O2 sensors.
I replaced the Bosch with NGK O2 sensor's, and car runs better. (from sparkplugs.com)
 
Ground strap?

Ohhh... wait.. I know what it is.. pull the plug boots off and reconnect them being sure that all 3 seat with a faint click.
 
I will check the ground strap. Pretty sure I remounted it. I seated the plug wires but there was no change.

tks sean
