My mom's minivan is messing up. It seems to be missing extremely bad. Looked around on some other forums, and decided to come back to my home forum for help. I ran a scan on the computer, came up with "Multiple Misfire" "Cylinder 2,4,5,6 Misfire." It doesn't seem to be the fuel pump, because around 4,000rshared_pm is smooths out. I just changed the Ignition Coil, and the problem still exists. Does anyone have an idea as to what it could be?

 

did u replace the plugs and wires

 

fouled plugs from the previous ignition coil. try plugs/wires. if that fails look for a vacuum leak

 

plugs and wires woulda been a good choice if my dad didn't take it to a shop and them find out it was a broke valve spring exhaust side. =/
