I have a 2000 caravan 3.0 L, with 265,000 kms on her, it will start and run brand new first thing in the morning until I leave the driveway and get about 300 ft down the road, it will start sputtering and backfiring and losing power for about 15 seconds, then it will roar to life and drive with no issues for the rest of the day. This is a daily occurance. I have taken it to a tranny shop and they have found no issues, I have replaced the fuel filter and changed gas stations, I did spray the wires at night and they lit up like a Christams tree sparking everywhere, so I replaced wires, pulled the plugs they still look brand new, cap and rotor are still like new. There are NO codes stored. I have pulled the battery overnight to resent the PCM but to no avail. Please help.

 

a scanner with data sure would help this as would an engine scope to see what cylinder(s) are being affected

 

Welcome to DF
Maybe a wire shortting out the crank sensor, dist pickup,or a cracked flex plate.Did you replace the dist cap and rotor?

 

I will start diggin tonie on the crank and dist wiring, is there a way to check th flex plate without separating the trans from the engine. the dist cap and rotor were done a year ago and are still brand new looking, I checked it when I pulled the plugs and put new wires on.

Thanks for the help, keep em coming

 

with a quality scanner or and engine scope, you can easily pinpoint the exact cylinder and determine what the cause is
