Hide your cats!
so whats the code you keep clearing? usually if you havea code clears and it dosent come back then it was a fluke, but if it is always coming back then there is a issue.
yeah mine does the same thing, the volt gauge also drops when the lights dim but then it will go right back up and the lights will come back to normal. i thought that it was my batteries and the alternator was just trying to catch up until i read this... could be the heater grid just kickin on and offok so heres an ADD ON newbie question to this topic LOL
when the heaters cycle on and off, with the load on your ALT and what not.
do you guys hear it on your engine.
mine runs super smooth but i think its when the heater kicks in or out
i hear a VERY slight bump in RPM, just for a fraction of a second. so slight that if your not standing there listening for it you may not hear it.
its like one piston gets a tiny bit of a bigger shot of diesel or something
anyone else hear this ???
In addition to plugging it in as "mstoaks" suggested, also get a dealer to implement high speed idle option because the engine won't warm up at -30 without it.I work 2 weeks in 2 weeks out in the Canadian North and the truck sits for 2 weeks in -30 celcius weather but is plugged in. Is it a problem if I don't start it and let it run a few minutes for those 2 weeks? Is there any problems that could arise or what?
Any help would be awesome!
Mine will do that when the heater cycles, even when its warm and i shutdown and restart a few mins later itll cycle a few times as i start driving but if your just driving down the road with a warm engine and its doing it randomly like after 15-20mins of driving then thats weird. this of course during cold temps onlydepends on the day. and it does it even after the engine is warmed up
I would definitely check your fuel pump relay before anything else , they can be very temperamental andno its all stock, i just really want to get this figured out before winter. if shes stubborn in 40 degree weather i dont even want to know what shell do in 32 an below. and when its crankin theres absolutely no sign of it gettin ready to fire. when it finally does fire it jus does. its not like its strugglin ya kno?
