I have been running these type of plugs for almost as long as they have been selling them. But about 2 months after installing a new set, my engine light is on and when I get on the gas it wants to stall out.
When the dealer plugged into my truck to see what was wrong, it came back with a misfire code for cylinder 1. They then noted that I had Bosch plugs and said that my vehicle should only have NKG or Nipandosno.
It cost $97 today for them to tell me that I needed spark plugs.
I'm guessing the real problem is my fuel pump or injectors.
I've already replaced the filter, any input would be appreciated.
