Ram Hemi misfire after rain

Hello, I have an 06 Ram 1500 with the Hemi 5.7. After rain the check engine light will flash and the truck will miss once or twice. Then, the light stays off and it runs fine until the next time it rains. I took it to the dealer still under 3/36 and they said the code was multiple cylinder misfire. (did not tell me code number) I asked where the water could be getting to and causing problems. They reply "the misfire cannot be related to water". Anyway, the misfire only occurs after rain and only in the first minute or so of driving. I have 34 days left on warranty and would like to get this figured out on Dodge's dime rather than mine! Oh -- I should mention the first time this happened something definitely smelled hot and caused the truck to stall. No hot smell or stalling since.

Try spraying water while it's running on the engine, plugs, wiring from a spray bottle to see if you can locate where it might be acting up from!

A cracked coil case or wire insulation can cause tracking, which means corrent can leak offand ground to near by engine & components more so when moisture gets on them which conduct electricity very ease. try runing the engine in a dark area and lok for sings of tracking,it should look like a little lightening storm

What causes CEL to flash for 1/2 mile and then go off and then not start at all after rain but start when dry?


The check engine light flashes when there is a catalytic convert damaging advent happening , like for a sever misfire . When a vehicle has a misfire problem no combustion happens in that cylinder dumping raw fuel into the catalytic convert , were it burns causing the substrate to melt . To buy a new converter could cost up to a $1,000.00 bucks ! You don't say what make ,model an year vehicle you have , so I can't say what could be wrong ! Plug wires , coil's , distributor cap if yours has one . If you have it check for DTC'S - diagnostic trouble codes , You probably have a P0300 random misfire or a P0301 - to P0308 depending on the number of cylinders Check Engine Light On

Driving in rain. 'Check engine light is FLASHING! Why?


check engine lights report on engine and transmission faults
if it is only in the rain I suspect that the wires and connections to the box or in the engine compartment are being affected by water getting into the couplings in the harness.

04 DODGE Ram hemi cylinder 3 misfire


Check engine compression and compare. then test running engine compression most engines have about 130-170 cranking compression and about 90-110 running compression. OR bring that cylinder to its Top Dead Center compression stroke apply air to the cylinder and check to see where the air is going open throttle plate bad intake valve, from exhaust pipe bad exhaust valve, from oil cap piston rings.

Flashing engine light on ford freestar,engine is running very rough at higher rpm


A flashing engine light usually indicates a misfire or several misfires. If the ignition components (coils, wires, distributors...) some how become exposed to moisture it is possible to get a rough running engine due to misfire(s) cause by arcking.

Check engine light 2007 ram 1500 hemi. I've owned


There is no standard interval for the CE/MIL light. You need to get the codes scanned at a local AP store to see what codes you have.

2005dodge ram 1500 Hemi missing when taking off


404 & 406 appear EGR related. Check all hoses & connections at EGR. My guess is once EGR is fixed 430 will disappear. I believe EGR is just below & to left of alternator, 2 small bolts holding on.
