Engine starts, then after a while it just dies, cranks but wont start. Its been doing this for a while (around 2 months) most recently when cranking, it back fires and throws a lot of smoke by the air filter housing. I have replaced coil, plug wires, distributor CAP and rotor. I have voltage from and to Crankshaft position sensor and camshaft position sensor, even when it stalls. I noticed spark is weak, both in distributor and right off the coil (in both, old and new coil). What should I check next? Could the ignition switch or shift lever position sensor be causing the stall?
Thanks in advance for your advice.
