Engine And Engine Cooling Problems of Toyota Toyota Truck

The problem that exists is on my 2003 Toyota tacoma. It will all of a sudden lose power and have no throttle response, almost as if it was hitting an engine governor. The rpms usually drop anywhere from 200-500 and then comes back up. The power would slowly come back after keeping my foot on the throttle. It consistently does it after accelerating out of an intersection (usually around 25 mph or while cruising (around both 45 mph or 75 mph) on the highway. This drop of power or lack thereof is a huge safety issue, especially when pulling into an intersection or needing quick acceleration to avoid an accident. I have read about many others with the same issues with their late model tacomas. The parts to fix the issue are very costly and the problem seems to be widespread.

My folks happen to own a 2000 Toyota tacoma pickup, 4-cyl with/auto transmission since it was new. When the air conditioner is in use and the driver applies the brake, the vehicle will lurch forward. Also, the vehicle will lurch forward when the fan is turned-on, with the air-conditioner switch already on which activates the air-conditioner immediately. I assume this conditions exits to compensate for the air conditioner load on the engine. However, I've driven many other vehicles that function just fine when the air conditioner is activated without having to lurch the vehicle forward, especially when the brake is applied. The problem has several times nearly caused an accident with pedestrians and other vehicles - near misses. My folks have taken the vehicle to the Toyota dealer several times and the dealer keeps claiming that the vehicle is functioning as designed. So it appears that Toyota has acknowledged that they purposely designed a vehicle that will lurch forward when the brake is applied and the air conditioner is on. I had to check this out for myself because it seemed too ridiculous to be believed and I was surprised when it happen to me. It takes an abnormal amount of pressure on the brake pedal to keep the vehicle still when the air conditioner is activated and the slightest release causes the vehicle to lurch forward. This has been a going on since the vehicle was new so the date below only a formality to file this compliant. If there is any interest in this complaint the vehicle is available for review.
