My truck keeps ideling at the light the it will cut off it shakes a little then cut off i checked the battery and alternator and starter its all ok what could be wrong


This sounds more like it may be misfiring, when you get a misfire the engines idle is lower than normal and also the engine will shake as all cylinders are not firing and inturn cause the engine to stall out, the check engine should be on if its being doing this for a while (few days ).have the computer scaned and see if the computer has picked up a misfire, the code will tell you which cylinder or cylinders are mis firing, from there you can check the sparkplugs and also the coils. there are many auto part stores that will scan the computer for the codes at no charge and give you a readout. good day

The number 3 plug is the third one back from the front of the engine. They are numbered in order 1,2,3,4,5,6 front to back, this is the cylinder numbers not the firing order. Firing order is 1-5-3-6-2-4 .

you need to have a code reader hooked up to your truck, some major parts stores can do this for you,be sure to write down the codes they find, and ask them to clear the code memory. you may have a sensor in the transmission that has failed, the diagnostic codes will give an indication of what part has failed
