Did some exhaust work on a MSP last night. Went to start it up and test drive it and it run like s***. The customer had told me he had changed the plugs with some big dollar off brand. It felt like a dead mis to me. The engine was not hitting on all four. Removed the plugs today to install some NGKs. Take a look at the number three plug. It had been hammerd real bad. Hit the piston hard also but the engine seems to run good with the new plugs.
Next anyone goes to the store to buy plugs, please get the normal plugs. Do not buy plugs that some cowboy is trying to sell. He will not be paying for your new engine if it fails.
