Hey guys,
A brief intro as this is my first post;
I recently bought an ‘04 100 series after quite the extensive search. She’s still just a baby at 120,xxx miles and since purchasing her I’ve dumped thousands into baselining her and getting preventative maintenance under control - timing belt, water pump, spark plugs, coil packs, fuel pump and filter, every single fluid changed out, gaskets and seals, wheel bearings, rotors, pretty much everything.
The vehicle has been absolutely incredible and has already seen thousands of miles in the few months I’ve owned her; but one thing constantly bugs me.
When traveling at interstate speed (60-70mph) and I encounter an incline (like going down I-70 in the mountains) she feels like she really struggles to maintain speed. Even with cruise control engaged, the vehicle will push 45-4700 RPMs just to maintain 65mph on the highway.
Normal driving in the city is completely fine, and the LC has no issues engaging any gear; it just seems like she struggles on inclines. I assume holding near redline for a 5-7 degree grade isn’t normal; so any suggestions on where I should begin?
Tire size is 275/70/18 in case it’s brought up; completely stock otherwise. If this is normal please pardon my arrogance.
TL;DR- 100 series needs to be at 4500+RPMs just to maintain highway speed on a slight incline
