I'm new here. I've had my maxima for about 3 months now and am still learning. I'd like to show what I've done so far as well as ask,some questions. When I first got the car it missed terribly when it was cold. Since then I've replaced all belts, harmonic balancer, crank case pulley, spark plugs, coil packs, and exhaust. It still misses under heavy acceleration like it bogs down and still misses when it's cold. I also recently added Tein street advance coil overs. I now had a vibration under acceleration, but I'm not sure if my cv axles are in a bind or if my tires were not properly balanced as I've found the weights are about to come off. Any help would be appreciated. Thanks
