Crysler voyager -95 3.3l Backfiring in aircleaner
My Voyager is backfiring in the aircleaner at 3700-4000 rpm when i
drive it and if the gearbox is in park and i rev it up to the above rpm. It starts to missfire slightly and if i press the gas even more it will backfire so much that i even blown a aircleaner top off. This happens almost everyday but sometimes it will run perfektly. I´ve changed wires and plugs whith no change. There is no error code in the "check engine lamp" only 55. Is there someone that can help me, i´m going crazy over this. I´ve read a lot about mis/backfiring here, but nobody seems to have exactly the same problem as me. meaning at a specific rpm regardless of load/uphill/downhill/decelerating/in-gear and so on. Help please!!!!!!!! Janne |

spark and fuel pressure is not monitored by the pcm to set a fault code, you
may have very well damaged the coil. especially if you kept driving it with this problem "Janne S Sweden" > wrote in message om... > My Voyager is backfiring in the aircleaner at 3700-4000 rpm when i > drive it and if the gearbox is in park and i rev it up to the above > rpm.

I have thougt about the fuelfilter before but i don´t think that´s it
because i can load the car with a big boggie caravan and it works fine in the range under the 3700rpm whith the gaspedal to the floor. So i tink it gets all the fuel it want´s.

I"d do a coil pack, wires, and plugs.
