My 95 12v has recently started giving me troubles starting periodically in the mornings after a rain or temp change. Temp hasn't gone below the low 70's though. It will crank and fire whats left in the injectors, but then would die. I've kept cranking and even floored the gas. It would gain small rpm, then stall out. Shoots white/gray smoke when roughly running. Just changed the fuel and air filters when it started giving me issues. Past times it was able to start once the air filter was removed, still had a hard time to get going. Once it starts there is no issues. Runs and drives great. This issue is not a regular occurrence, but is becoming more common. Any advice or ideas?
