i have 2007 Ram 5.7 hemi and on start up the engine revs high then idles... the engine light came on so did the ETC light flashes. I tried the key trick to get any codes. Computer said DONE and no codes were listed. What could be the problem?????

Thanks

 

Which method did you try for codes?

Turn the key to on then off, on and then off then on and your cel code should display.
The other key trick is a gauge test and will not show cel codes.

 

I did the on off on off on thing. Just said DONE and the ETC kept flashing. It's in the shop now being diagnosed. So hope it's simple. The truck is 207 km over the warranty. Never fails.
Thanks

 

Auto parts store will pull the codes for free.

Sounds maintenance related to me. You are at about the right time for the EGR to fail and if you're over 30k miles and haven't cleaned the TB, it'd contribute also. Did you do plugs, fluids and filters at 30k miles?

 

Just bought the truck 2 months ago so not sure bout the prior maintenance. looks like I better do the works. Plugs wires tune up the whole thing.

 

Stop by an auto parts store as Hammer suggested and let them pull the OBDii codes for you and post them here or get a tuner for your truck and do it yourself.

 

Drove my truck to a friend and he scanned it. No codes were found. After inspection it the throttle assembly we found a wire in the harness chewed by a mouse. We repaired the harness and the etc light and engine light went away ant the truck drives fine now. Thanks for all the help.

 

That'll do it.

I still would start to tackle the tune up stuff, at least a project or two at a time if you have no idea when it was done last. That's a big investment you got there, no sense having a serious issue develop for lack of spending a couple hundred in maintenance...

 

Had that happen once on a car that sat up over the winter. Those bastards chewed through a lot of my wires and vacuum lines.

 

No plug wires on a 06-up Hemi, just two plugs under each of the 8 coils.
