Re: engine light and cuts out at freeways speed when...
Have you changed your fuel filter lately? I had a vehicle once whose fuel tank that had a rusty seam. Every 10,000 miles or so, the rust flakes would clog the fuel filter, and the engine would sputter and stall when the vehicle was climbing uphill. If you idled for a bit, you could drive on for a ways, until the same thing happened.
A nearly dead fuel pump could cause the same problem, I suppose.

What you are describing sounds normal. RPM's stand for revolutions per minute. Each minute your engine is running, the pistons are going up and down. When you are not going anywhere, your engine is idling and so the RPM's should NOT be very high. However, when you race up a hill, your RPM's SHOULD be high because your engine has to work hard to climb the hill or to go fast.
Idle speed= 650 Revolutions Per Minute. That means your engine cylinders each work 650 times in One minute.
At freeway speeds, your engine will revolve somewhere between 1600 and 2100 times per minute. I hope that helps.
the p38 is a bit sluggish and slow on long steep hills, really not geared for performance but more as a piece of heavy equipment. strong horsepower wise very formidable powertrain but you're not going to have that get up and go that many drivers look for. couple quick suggestions you may want to check your plugs and wires a common weak spot in the ignition system, and i might suggest also running i can of seafoam through your engine. you deposit in your gas tank runs through with the half a tank of gas. i'm not a big advocate of fuel additives or octane boosters but in the case of seafoam it's definitely a worthwhile and proven product. don't forget also your sport mode button down next to your shift lever push that button down and it keeps your transmission from overdrive so you can accelerate into freeway traffic and climb hills without your transmission shifting
Read the engine light on the OBDII then post the code if your code reader doesnt have the explanation of the code ,although i would suspect a faulty O2 sensor not giving the right fuel ratio but ? iam always wrong here when i guess things
i know the camp verde hill of which you speak , last vehicle in the shop with that same scenario , after doing everything possible including a catalyst check , as we could not duplicate the problem , we replaced fuel pump at owners request and next trip he confirmed it was a fix .
That could be caused by several things. Is your check engine light on? If it is on it could be due to a number of sensors such as the MAF(mass air flow), MAP(manifold absolute pressure), or EGR(exhaust gas recirculation). However if your check engine light is not on it could be caused by bad plugs and or wires, lack of fuel pressure caused by fauly fuel filter and or fuel pump, or it could be caused by the timing being off a few degree's. Please provide me with the engine size and any work that has been done to that vechile recently to help rule out some of these possibilitys.
