Daepp, I would try to rule out any possible ignition issues. Over the years, I have had some funny idle and part throttle misses from one brand or another of spark plugs, so I might do a spark plug change. Also, I would check the resistance of all your plug and coil wires from terminal to terminal. A couple of years ago a friend of mine had a funny miss on his 2.7, turned out to be a bad connection at one of the spark plug terminals.

Pressure opens the injector, the mfi cam pushes the fuel out in time with the cams.

Could be running too rich at idle and low speed. They like to be rich to help get rid of the flat spot at about 1/4-1/2 throttle. Rich at idle and above 6% c/o will cause a very definate miss. Have a shop sniff it with an exhaust gas analiser to see how rich it is. Lean it down as needed but the flat spot may show up. Also make sure the thermostat on the pump is getting hot air and shutting off. Mark Kinninger
