Hi....
I have some ignition problem on my van. It feels like it have a missed
ignition some times, og a little bad ignition on some sylinders.
Have new spark plug with correct gap.(checked many times) and new wires
(Changed twice) and new cap and rotor (changed twice) New cleaned and tested
EGR valve. IAC tested and seems to funktion OK. No vakum leaks. (tested
alot) new gasket between upper and lower intake manifold. New gasket for IAC
and trottle body. New Coil.
New O2 sensor. New tempratur sensor and new map sensor.
Adjusted timing correct many times, but don't seem to help, it still misses.
Can miss alot when cold, so run find for a while, and start missed alot when
hot again.
Coul it be the ICM ignition control module? Or could it be the ECU
Electronic control unit?
I have looked over and cleaned alot of connectors, but it don't seem to
help.
Anyone have any ide?
Regards...
