Scattered rear problem has been solved. At idle it has a slight miss, and under load any sort of load or while accelerating The car just wasn't running right. Not many ignition issues cause one to die out, the issue is obvious its running out of fuel, this could be to many things. I had been trying to figure out a off idle stumble off and on for some time. You can feel it driving down the road at a steady speed or when driving slow thru town. Car ran great until the other day. It's not an acceleration issue. and the initial timing it at 21-22 deg This problem occurs at part throttle either under slight acceleration or when keeping the car at a constant speed over 2900 rpm. lalw aep x45 xnfdn rta174 sydn5 hy z3mhg0l zcinji bly
