Question about 2001 Hyundai Elantra
I have an 01 elantra. It is getting about 19 mpg highway. Sometimes when i hit the gas it revs to about 4000 rpms but doesn;t really move very fast. also when i am in the 60-70 mile per hour range it has no accleration. there is no check engine light and i just past inspection where the mechanics said they could not find the problem while driving it. It almost feels like an old car with the ac on...it loses power, but mine happens with the ac on or off. I have read about 02 sensor, fuel filter and maf sensor...all of which are supposed to throw a code...any ideas?
I have the same problem as talked about above. 2002 Hyundai accent gsi. HORRIBLE gas mileage. I only get about 320 km per full tank. My driving habits are good. i took it to the garage and they put it on the computer and no error codes showed up. Question: Can a MAP sensor be faulty but NOT show up on the computer diagnostic? I had my O2 sensor checked out and my exhaust, and changed the flex pipe. Car runs pretty good just horrible gas mileage and kinda crappy power. Changed fuel and air filter. Cleaned the fuel system entirely ($80 at garage not $4 bottle).
Anyone ever use a resistor in the MAP sensor?

Try changing the MAP sensor
my hyundai ran really bad and skiped and cut off then i change that 45 dollar part and now i get 350 mile to the tank in town.

O2 sensor is the most likely problem - the one before the catalytic converter, not the one behind it. Also, get electrical contact cleaner and clean all the sensor harness connectors you can find underhood. Finally, run a Seafoam treatment (Seafoam is available at parts stores) through the car, and see if that takes care of it.
