Hello everyone, I just picked up a '91 C3500 Dually with a 454. The truck has been great the last few weeks but the only real issue I'm having is driving on the freeway. Once I hit 65mph, the RPMs start to fluctuate up & down almost as if it's trying to govern my speed. The truck will go faster than 65, but it's almost fighting itself along the way. As soon as I'm below 65mph, it's back to driving normal again.
The truck has no issue accelerating and pulls very strong, but the only notable thing I can mention is that sometimes the idle is very low at start up. It'll idle fine on most start ups and I haven't had any issues while at stop lights.
Any info or recommendations would be appreciated, I have not tried trouble shooting it yet.
Thanks
