this morning im heading down the highway and my dodge stalls out.shift into neutral and restart it.this continues for some time along with loss of power issues.when i get to my destination it finally dies completely,wont stay running.seem to have a lot of black soot on the end of tail pipe.just wondering if any of you guys have a clue what would cause this before i start throwing parts at it.i have been consuming a bit of oil in the last month or so and its been 4 years since i changed the plenum gasket(did not use the hughes kit).

would a plugged cat cause this? i broke down 220 km's from home,thank god i have a CAA membership.

thanks

 

Maybe.....

See what you are missing, spark, or fuel.

 

tomorrow if it stops raining, i will pull a couple spark plugs out and see whats going on.damn truck almost gave me a nervous break down hurkin and jerkin down the highway.think it gave me whiplash.lol

thanks heyYOU

 

Send some of that rain this way.... 104 today.... (an no, that's NOT the heat index, that's the actual temp....) Not exactly typical for Michigan....

Wasn't just something getting wet was it? Is the seal at the back of the hood still in place?

 

Could very well be a moisture problem,weird that its never happened in the 16 years ive owned the truck.gonna get up early in the am and start probing,maybe throw a set of wires,cap,rotor and new plugs in as well.104 in michigan is nasty bud,never seen it that hot here in central ontario.what end of michigan are you in?

thanks again.

 

Right in the middle, at the bottom. I can throw rocks at ohio, and almost expect to hit it.

Yeah, the weather truly sucks. Supposed to cool of next week.... down into the high 80's, low 90's...... whoopee.

 

i pulled a couple of spark plugs and they had a nice brown colour.sprayed the distributer cap,wires and coil with water and the engine did run a little rougher but ran properly when i test drove it.i dont have a fuel preasure tester but when the scrader valve was depessed fuel did spray out.im sure it was not near 45 psi by any means.wish i had a proper tester to eliminate that potential problem.not sure how to check for a plugged cat,put my hand over the tail pipe and the preasure did seem low.but im not sure what kind of preasure should be there.
wonder where i should go from here??????

thanks

 

Pull the front O2 sensor out of the exhaust pipe, and see if the truck runs any better. (disconnect it as well...) If it runs better, cat is on it's way out.

 

ok heyyou,will try the o2 sensor trick.i did compression test on 1 cylinder and am about 130 psi.will check all the others later.borrowed my buds OBD2 reader and found 1 code,"evaporitve system leak very small".i did have the battery disconected for awhile so the codes may have cleared.gonna take it for another spin untill it acts up the throw the reader back on it.

also forgot to mention that i pulled the plug on #8 cylinder and it was nice and clean

thanks again

 

after doing a lot of reading i decided to replace the crank position sensor.i already had one here so figured what the heck,lets try it.this i quite possibly the worse thing i have ever tried to do.took me an hour to get the old one out plus 1 hour later i still cant get the new one in.cant get the sucker pushed into the grommet,is there any trick to this?i know for sure small hands would help.

thanks
