So I clear the codes.Start the vehicle no issues no Dtc.Shut off restart and with in seconds Dtc and same codes appear on the scanner.Also swapped #1 and #4 coils and wires no help same codes.Also I checked and changed some vacuum lines behind the vacuum pump.Checked #3 wires and plug no issues except still has lots of dielectric grease in the wire.Im confused what is causing this.Three cylinders showing the same issue.Also changed battery with an newer one I had and charged the voltage running is 13.8 a little low and the battery charged shows 12.3 volts.Also the codes associated with these are 3053,3052,3054 all associated with cylinders 2,3,4 any other suggestions.I donít have a real problem changing the coils and wires.Plugs are fairly new.Also this all happened after my wife hit a hard bump in the road.

Makes me think this is a spark burn time problem. RE: The amount of time the spark plug is arcing.

Have you pulled the plugs? Without researching farther, I'd say the gap is too large. Did you ohm the plug wires?

Well I thought that and pulled number 3 cyl b plug and regaped and as I did swap #4 and #1 cyl coils and wires but not plugs.Still the same.I did not change the wires out when I did the plugs in the fall.I will try new and plugs maybe their bad.
