I have a 2000 dodge ram 1500 5.9, and yesterday it would start but quickly stall if I didn't keep my rpms up with gas pedal, so the retired mechanic across the street took the air filter and housing off of the truck to see what the issue is and he says clean the throttle body out and get new filter so he adjusted the idle higher so I could get back home and to get truck to shop this Wednesday. but now the next day the truck has NO BUS error code and all dash lights and no gauges working???? what do you guys think the problem could be? do you think he didn't plug everything back in and that's why? also what do you guys think the original problem was? I sincerely give thanks to anyone that helps

 

that truck starts fine but all the lights are on now with NO BUS code

 

Check battery connections and grounds including the one on firewall by PCM. Make sure the PCM connectors are tight.

 

no more "NO BUS" or dash lights they are gone and gauges are working as they should, I checked fuse panel and popped hood and that guy put part of intake that says "dodge magnum" on backwards, put It back right way and no lights, also blew dust out of fuse panel

 

so I wonder if all it needs is the throttle body cleaned or new IAC Valve? or possibly tune up

 

it would idle rough prior to this all happening

 

I would remove tb and clean IAC and port just to be sure.

If plugs and rotor have been there a long time, it may be due. Check plug wires also. Never hurts to be sure. Do NOT turn distributor - it changes fuel synch and doe NOT adjust timing on these.

 

thanks for your help man, I'm taking it to the shop Wednesday. it also had a disgustingly dirty air filter, so I'm gonna replace that as well.

 

You can do it yourself at home. Pretty simple task.

While you have TB off, it would be a good time to look inside and see if there is oil pooling in the bottom.

 

Yea, easy stuff. Hope you get it figured out. And please, in the future use a better thread title in the (tech section) other than , "i need help! seriously". Reason being, anyone that does a search with the same problem or related, isn't going to search for " i need help! seriously" . Thanks bud,
