My Sonata 2002 has over 115,000 miles on it. Lately, when I push down on the gas the car acts like it is not going to respond, then sputters and finally I am able to drive. Also, when I am stopped at a light and push on the gas it does the same thing, but seems like it will stall, but if I pump the gas it picks up like usual. I have not had the oil changed in about 3 months, but could this be the problem?
Thanks in advance
Normally I would not expect that not changing the oil will cause the symptoms you are describing. There are many things that can cause what you are describing, and it may be as simple as needing a tune up with plugs and wires.
The quality of gas you are using could be the problem as well. Try running some good quality gas and see if it makes a difference at all.
At your mileage you may be looking at a clogged fuel pump or an air leak, amongst other things. Crank shaft position sensors and mas air flow sensors are also common on this vehicle, but if you do not have a Check Engine Light on as well, I*d lean more towards a tune up to start with.
I would have it checked out by a technician that you trust before it gets worse and possibly leaves you stranded.

Three months is a very acceptable time for an oil change. I*d be very surprised if the condition of the oil was causing these problems. There could be a number of possible causes for this condition, including a problem with a sensor, the gas or the fuel injection. I recommend you bring your vehicle to a trusted technician for proper diagnosis. If you are having trouble finding a reliable technician, check out Ask Patty*s list of female friendly shops.
