97 Dodge Dakota 5.2 V-8 intermittent idle problem

From : kvh

Q: . in about 3500 miles it has cranked but would not idle 2 times what about off idle if you can keep foot on the gas pedal chances are it is a dirty throttle body or a faulty ais motor automatic idle speed there is a tsb out on that glenn beasley chrysler tech i bought a 97 dodge dakota about 4 months ago and had thought it was the best running truck i had ever owned. in about 3500 miles it has cranked but would not idle 2 times. you can keep it running and get to garage and it will run perfect. the check engine light does not come on. the mechanics say it has to mess up before they can find the problem.it is almost like it is not getting gas. anyone else had this problem. kvh .

i have a 2003 dodge ram and the left break light keeps going out. i have changed the bulb but it doesnt help. it seems to be wiring... does anyone know anything about this probably a bad ground. a poor ground connection will draw excessive current through the circuit and through the filament which isnt designed for that much current and burns out prematurely. unplug the connector from the taillight bucket and try and clean the contacts as much as you can. ok ill bite. how exactly does a bad ground increase the current draw -- if at first you dont succeed youre not cut out for skydiving .

time to further your education again sheeesh . . . and you claim to be such a great mechanic. and by this crap you posted below far more of one than you. while i admit that my thoughts were wrong concerning flow in relation to the bypass they were no where near as bogus as this crap from you. the bypass allows coolant flow to the heater core for faster heat to the drivers compartment hahahahahahahahaha!!!! the heater core coolant lines and the bypass are in parallel with each other so how exactly does it do this sorry budd but you simply dont know wtf you are talking about. the purpose of the bypass it to allow the coolant to flow within the engine bypassing the radiator when the thermostat is closed to allow a normal warmup and prevent hot spots and engine damage. on the moderns dc products the heater circuit also does this all of the time but on the older models there was a valve that shut the flow to the heater core off and when it was closed the bypass was the only path to keep the water moving. this is where my thoughts were in error as i didnt take into account that the bypass actually bypasses the radiator and its hoses but at least i know what the bypass actually does. good stable engine / radiator flow can be had faster if you just use a couple braincells and plug in the heater with the engine already warmed up. wtf are you talking about this is a heater not a pump. it does not require stable engine / radiator flow to do its job and as jerry pointed out since it is in the lower hose it can feed heat to both the engine and radiator regardless of the position of the thermostat. and if youre thinking of that little tiny air bleed hole in the thermostat youre wrong there also. that hole effectively is not there as far as coolant flow is concerned. it has a flow rate of less than a gallon per hour. how much flow do you really think that you are going to get with the convection currents it can create it is not important anyway since it uses both convection currents and normal heat transfer to do its job and with its location does not need normal coolant flow anyway. really tom you need to accept that your mechanical abilities are so underwhelming. funny you should say that since here they seem to be way above yours. and you wonder why i have the attitude that i do. i asked you a simple question and instead of getting a valid response you come back with your typical insults and childish attacks. the funny thing about it is that not only was the response childish it was also completely wrong and every bit as dangerous to others as you accuse most of mine of being. i guess i was right all along all you really do is accuse me of you own faults to make yourself feel a little better. but like i said before budd if that is what you need to do to make your life a little better go for it. you have my blessing. -- if at first you dont succeed youre not cut out for skydiving .
