When testing the ignition for wet weathe issues. I mix a bottle of half water/ half ammonia, and spray the plug wires and the coils, if there is a bad connection or spark plug wire with any high voltage leakage this will find it.

1995 dodge neon cuts out during normal driving runs at full throttle


hi I assume this is a fuel injection vehicle and if so it sounds a lot like you have a throttle body problem or throttle sensor problem ,have you also checked that the fuel filter is not blocked,remove the fuel filter and blow thru it in the direction of flow and if your cheeks blow up while blowing thru the filter it is blocked or restricted -replace.
hope that helps .

My ford windstar 2003 hesitates during cold weather or wet conditions. But good during idle. Some time shows blinking engine light.


The flashing and rough running is to to a misfire or misfires cause by arcing due to moisture on ignition components. Eventually these misfires can lead to other problems such as damage catalytic converter. Start by identifying which cylinder(s) is/are misfiring. The arching can be reproduced with a spray bottle filled with soapy water. Spray the ignition components (wires, coils, distributor cap...)and look for the vehicle to idle rough. Replace any faulty component.

Po302 po303 po316 code


The Codes 302 & 303 are cylinder misfire codes,google them

Spark Plugs have nothing to do with misfires,it would be rare in
a life time if one ever failed to fire

Forget the 316 just misfires on start up

A repair shop would be your best choice without knowledge,
reference material & test equip

Ignition coil or vacuum leak problem

Buick rendezvous misfire issue


Since you changed parts, you have covered some possibilities. On the spark side, the Crankshaft sensor and( if equipped) the camshaft sensors give the information for the firing Pulse.

A wet connection on either part can certainly cause a misfire. There is also the possibility of a fuel injector misfiring due to a connection or bad ground on the injector during damp weather.

Sometimes if you get lucky you can see spark jumping on the motor by operating the engine in the dark. Mist the engine with a spray bottle of water to see if you can induce a misfire, if unsuccessful with normal weather conditions.

WD 40 often cures moisture problems.

Please rate my info.
