The red lightning bolt with two lines on either side light on the dash was flashing all the way, only had about 2kms from my driveway, thank god.

Anyways, I was on a two lane highway, signaled out to pass a car and trounced the gas to get by, then that light came on and I slowed to about 30-40 km/h. It was cold outside, -20 Celsius, but the temp gauge was at the middle mark.

So I limped home, put it in park and the truck starts to shudder quite bad. So I turn it off right away, check under the hood, nothing is glaringly obvious. I start it up, and it's fine, 100%. I even took it around the block to be sure.

Does the Hemi not like to be driven hard? Or is this a normal occurrence for rams?

 

It really likes being driven hard. You might have a grounding issue with the TB, or, You may have a TB thats just acting up, Try running a ground wire from the engine to the TB and see if that doesn't help.

 

It hasn't had a hiccup since... I dunno. Maybe it was a one time thing.
