Your problem could be caused by numerous things, how well was this car maintained? A good tune-up should rectify your problems, oil change, air filter change, tranny fluid and filter change, plugs and wire's, coolant flush, timing belt, thermostat, fuel filter are all things that you should have done if they haven't been done recently. Let me know what you have or haven't done on the car and I can try to diagnose further.

Hope this helps

Need info on timing belt 1998 hyundai elantra


The timing belt is normally replaced at 100,000 km (approx. 60,000 mi), but must be checked for wear and tear starting 75,000 km(approx. 45,000 mi) along with a major tune-up.

The switch near the shifter is the ECT (transmission control) which selects NORMal driving mode, and PoWeR mode. It is the battle between economy (NORM) and driving performance (PWR). As tested, the PWR mode delays your A/T upshift to a higher RPM. This utilizes your engine's higher revs, but really cuts into fuel economy.

Hope this helps.

2008 Toyota Highlander Sport AWD when starting off the engine seems to rev fairly high for very small vehicle movement. At idle engine revs around 1000RPM. Gas mileage is poor,17MPG for about 80% city, 20%...


yes it is normal many customers complain about how the newer cars are not as responsive from a stop basically you have to hit the gas then the car goes seems to rev high to people with not a lot of movement becausse of this its because the newer cars are throttle by wire when you hit the gas it sends a electrical signal to the throttle to go instead of a few yyears back they were you hit the gas and the cable attached to gas pedal pulls back throtttle much more responsive hope this helps
