I have a customer that has a Nissan mpl02a25lv. CODE 27. I didn't have the correct OEM Shorter spark plugs. the plugs that was removed had a gap of.40 bad plugs. installed Autolite. SPARK PLUGS. And found #2 coil bad. So I ordered the correct OEM SPARK plugs, And a new coil. coil arrived 1st. installed ran a little better but still had rough idle and miss. Installed OEM plugs. forklift ran like a champ for 2 days. then code 27 is back.? Any ideas. Maybe check each coil. what a headache customer is 120 miles each way. PLEASE HELP.
