Now this problem is very intermittent, usually happens when its cooler out. Its a 99 lx470 and I could be cruising at 70 and all of a sudden it feels as if the throttle cut back and the truck loses power and it continues. If i release the gas pedal and then repress it goes away but comes back. There is no cel light and the problem is random. Ive replaced the TPS but no luck. Could it be the APS? Thanks!!
