Low power engine and high gas consumption

Hello,

It sounds like you have a mass air flow sensor that is out. These sensors can go out without causing a check engine light.

Here is a guide that will show you what you are in for when changing the sensor out.

I was scheduled tomorrow for service in hyundai. I want to know what are the other problems so that i can explain or i have an idea in every parts that they want me to replace. Becease i went to hyundai 2 weeks age to report that i have a low power engine and high fuel consumption after they tune up, change my oil and replace my air filter and engine wash, but they told me to replace my sparkplug. But the problem is still there.

tell them the car is getting poor mileage they may have a software update for the car that will fix the problem.

Please let us know what you find.

Cheers, Ken

Doyou think the clutch is the real problem here? Is it gonna cause the engine to be low powered in my 2nd my second gear and increase the gas consumption?

Yes if the clutch is slipping it will cause low mileage. You should be able to tell if it is slipping can you?

I dont know how. But i feel the engine is on low power and high mileage. I talked to two different mechanic: 1. The casa hyundai mechanic and 2. The shell philippines. They both told me that it was the clutch.

Okay, let us know how it goes :)
