Question about 2005 Hyundai Elantra
Trouble codes p0171,p0172,p0174,p0300 what do they mean. 2005 Hyundai elantra code P0172 & in 212 miles it took 3/4 tank of gas, RPMs go way up to 5 when you slow excelerate--help, of course the dealer can not find what is wrong
When I see all these codes i instantly think of two things. Vacuum leak especially intake manifold gaskets and Mass air flow sensors. Spray the engine with carb cleaner when its running and see if you get it to rev up,run rough or run different. Next unplug the MAF and drive the car, see if it runs normal.

I have the same thing going on except the RPMs going up to 5...I had the car rev up high when i punched it on the highway and then it did not go back down at first...i got off the turnpike and it shut off at the light but started back up again...shut off again...started right back up again and I never had a problem again. I am getting this same code you are talking about here and no one can find anything wrong with the car it is a 2005 hyundai elantra.
