goodday my name is darling and i own a 2004 nissan maxima. my car keeps burning out the ignition coil. I replace the ground cable and i throw new ground for all the coil and i put a new ground on the engine. I changed the 3 catalytic converter. and the engine was getting hot so i took out the termestat and i put the fan derectly so its on all the time. my next option im going to change the crankshaft position sensor or if u got an idea plzzz write back asap.
