I'm having the exact same problem on cyl 2. replaced wires, plugs, and looked at the injector, it looked fine. Ohm test on the injector reads 13.0-14.0 on all injectors. Voltage appears to be the same on all connectors going to the injectors. Tonight after over a month of sitting it fired right up, and took off with out a hiccup. It ran all night with no issues, until we left McDonalds and on ignition the hiccup was there. Then in the middle of driving, it smoothed out. I don't have the money to shell on a coil pack if that isn't the problem, but if it's the burnt valve how does one go about fixing that?

 

Replace it.

 

You sir are a life saver!!!! Thanks
