Last 3 weeks - initially seemed like power loss/surge, then heard unusual sound coming from engine compartment 1 week ago, engine started to die while operating on city/residential streets whenever not pushing gas (slowing to turn or stop) Friday, would not even hold idle to start, pushed gas and held RPM's at 1 - 1.5 for a while and finally started. Today, initially would not start. Next time started RPM's at over 2, dropped when shifted to reverse, when shifted to drive vehicle accelerated without use of gas pedal up to steady 35 mph on city street. After 1 mile, at next intersection started making that strange noise in engine compartment (like air or fluid under pressure ie air compressor/high pressure water sound) while pressing brake shifted into neutral RPM's revved to 2.5, in drive and reverse dropped to 1.5, in park revved to 2.5, after turn automobile accelerated to steady 40 mph on city street without gas being pushed at next stop (1 mile) returned to normal idle and operation. Has problem both when cold and hot weather and cold or hot start. It has not produced a check engine light or any codes

While driving in traffic the accelerator pedal became hard to press then engaged and unable to control speed]. all the while franticly applying the brake an trying to release the accelerator, I had to force the vehicle into gear [park] where the vehicle then revved into the red zone before cutting off. I then tried restarting the vehicle up and again the accelerator remained engaged [stuck] and would not release.

Isuzu Trooper 1999 problem after problem, engine burning oil. After the engine was replaced, the engine light illuminated at least 30 times. The dealer gave the consumer all types of excuses until finally they said they didn't know what was causing the light to illuminate. There were other problems such as a hard shift with the transmission, water leaking through the sun roof, difficulty starting the vehicle, uneven tire wear, in just 65,000 the consumer has gone through 3 complete sets of tires. The consumer was told there was a problem with the frame of the vehicle and it could not be aligned. The tie rods were replaced because they were defective. In the past the vehicle lunged forward while the consumer had her foot firmly pressed on the brake. The vehicle intermittently idled high while stopped. The vehicle has rolled backwards while it was in park. Another mechanic informed the consumer the previous dealer installed several electrical componets incorrectly and there were also some defective parts that needed to be replaced which caused the engine light to come on. The consumer was getting poor gas mileage.
