2007 LP640 Balloon White
I changed my plugs and air filters yesterday. Car has a low speed (low rpm) surging issue that I’m trying to resolve. Plugs were fine but replaced anyway. 2 coils looked like they had moisture at one point. I used some scotch brite to remove the corrosion. Zero improvement from the plug change, would like to Ohm test the coils and looking for instructions. Thanks all and Happy New Year!
