When the engine is cold, the accelerator is very hard to push. As I apply more and more pressure, it finally depresses but sticks in a high RPM. What is the cause.

The throttle position sensor may be misaligned. This tells the computer how much throttle is being applied, and when they go bad, or come out of alignment, the idle tends to get up there. If that's not the issue, remove your air cleaner, the housing and everything until you get to the MAP sensor. Give it a good spray with carb cleaner, let it dry and replace the air cleaner with a new one. If the MAP sensor detects minimal air flow, the computer jacks up the idle to compensate.

I had the same issue on my 99 Trooper.
It would usually start when completely cold, but idle around 2k RPM.
It would drive fine. But if I shut it down, ran into a store, and came back out, it would start but immediately idle.
Had to ride the gas a little to get it into gear.
The Check Engine light has been going on and off for 6 months or so.
I took this to my local trusted repair shop (no Isuzu dealers within 200 miles).
The diagnosed the light, and found that the Intake Gaskets were bad or leaking.
The idling problem was related to the car not being able to control the amount of air coming in.
They replaced the Intake gaskets by the next day, and I haven't had a problem since. And no more check engine light, which has been on half a year.
Here's some details from my bill:
(1) Intake Gasket set $107.95
Misc materials $21.00
2.1 hours of Labor
The total cost to me was $345.00, and I definately don't feel gipped.

It's fuel infected and it has a vacuum leak, most likely a PCV valve that is stuck open, I've seen a few now. Replace the PCV valve 1st, if that doesn't fix it, start looking for a hose that has come off.
SOURCE: slow acceleration, high rpm
This sounds normal to me! The engine will read that rpm when accerlerating lightly. It is the stall of the torque convertor. The oil pressure will always be higher when the rpm's are higher, or when the oil is thicker - cold.
Virbration? That is a different story. Oil won't cause that.

THE TROTTLE PLATE INSIDE THE THROTTLE BODY WILL GET DIRTY AND THE IDLE WILL NOT COME DOWN TO NORMAL.U CAN CLEAN IT W/ A THROTTLE BODY CLEANER U CAN BUY AT ANY PARTS STORE
Hi
1) If the gas pedal is hard to compress you could have a broken spring inside the throttle housing. The throttle housing is located in the sealed compartment of the cruise control housing.(The housing with the rubber bladder.) You will have to remove the rubber covering to inspect the inner workings of the throttle mechanism. If every thing looks intact push on the accelerator. If it is still hard to push in, you could have a rusty cable.
2) A simple can of WD-40 should be applied lightly to the inner workings of the housing parts.
Try the throttle again and if it is still hard to push, check the connections of the cables to the throttle apparatus. Use the long plastic tube on the spray nozzle of your WD-40 can to shoot lubricant in to the small openings of the cable sleeve.
3) It may take a few minutes of manipulating the throttle to loosen up the corroded cable connections. Once the cable slides and the throttle seems to move freely take a dab of Vaseline and coat the ends of the cable connections. Vaseline will keep the moving parts lubricated and protect the connections from becoming more corroded.
4) By lubricating all moving linkages, you can prevent further throttle sticking. Make sure you replace all coverings back to the way they were when you started. Sit in the drivers seat and push the throttle pedal a few times to ensure that the throttle is no longer sticking.
5) Take your car out for a short spin in a unpopulated area such as a empty parking lot. Start and stop the vehicle numerous times to check it out. If the gas sticks at a slow operating speed, you can simply put the car in to neutral, apply the brakes and switch the ignition off. It is always better to be safe ..
However for an easy solution check cable to throttle body, it may be kinked. This is a common problem. Remove the throttle body and clean the throttle plate with a throttle body cleaner. Clean the front and back of the plate. Just spray and wipe off with a rag. Do not scrub with a wire brush. Doing this can damage the throttle plate. You can buy throttle body cleaner at most parts stores. Make sure you clean up your IAC valve while its off, that thing gets gunked up bad after a while.
