Hi
The fact :
- 136400 miles on a '03 Venture.
- Run on 5 cylinder for 1 minute after crank. After run fine on 6 cylinders.
- Engine coolant is leaking but I dont know where : there's no smell like a defective IMG.
I get a noticable "P0304: Misfire cylinder #4" with CES blinking under accelerating.
The cylinder #4 is the front middle one : the easiest to check and access.
BTW i change plugs, wire and coil and still the same symptoms.
Any idea : fuel injector ?
Bst rgds
ps : All apologies for my poor "french touch" english
