Some one has to try this:
My brother in law is a Mercedes Mechanic. I told him I was having little problems with idleing etc. Anyways long story short- He thought my Magnecore wires could add to the problem I was having. He told me to turn off all the lights and look for any arching (while the enigne was running). Even suggested using a spray bottle to lightly mist over the wires. Sure enough there was arching coming off the wires. He suggested for me to go back to my Factory wires.
Any thoughts...
