Hi,
I have 39700 miles on my MINT 2005 Hyundai Elantra GLS sedan.
The car and engine are in EXCELLENT condition since day one.
I have been doing 5000 OCI with OEM filter since day one also.
At 30,000, did complete auto trans fuild exchange with Amsoil
and coolant flush and refill, new air filter, new Kumho tires
that are also properly inflated to 32 PSI and checked every 2 weeks, ALSO rotated EVERY 5000 miles and the car tracks completely straight without ANY pull to either side.
But suddenly, my gas mileage is suffering and I can understand
why!? ALL the maintenance is ALWAYS done on time.
Any possibility is could be either a BAD PVC valve, EGR valve
or MAF sensor??
The car runs beautifully smooth, but its just suddenly the bad gas mileage that has me concerned.
Any other thoughts??
