Question about 2004 Toyota Corolla
After a cold start and about 10 minutes driving at speed 50-70 mph, the car will not accelerate and seems to hit a flat spot or limiter. Pressing the accelerator to the floor just kicks out smoke. Changing down then allows you to keep up a certain amount of torque and sometimes clears the problem. I have had the car on a diagnostic unit at a local garrage which shows no problems. I have checked for fuel leaks, have changed the fuel filter and run though some decent injector cleaner fluid in a full tank diesel. This fault tends to shows itself after 10 minutes (only at speed) and does not occur again until a start from cold. The car had no problems starting, running and has plenty of pull normally. I am very puzzled. Please help.
You might want to check the MAF sensor(Mass Air Flow) and clean it with MAF/MAP cleaner. I am also kind of puzzled with this problem as I have a 2004 Corolla also, I only had power loss when my MAF went bad.
