The filter may be on the firewall or under the car by the fuel tank.The studering wouldtell me that it needs plugs and wires.If it is running smooth but no power up hills or hard take off I would have the fuel pressure checked.

When going down the road my car quits and in bout 10mins starts back and go bout 6 miles and do it again


Check fuel rail pressure. Low pressure could be due to clogged fuiel filter (cheap to replace) or a defective fuel pump (not so cheap...).

How do you change spark plugs in a 2004 hyundia sonata


It depends on which engine is in the vehicle. The 2004 Sonata came with two possible powertrains -- the 2.4 Lit L4, and the 2.7 Lit V6.

On the 4 cylinder engine, there are two coil packs and two ignition wires, Below each coil pack is a spark plug (#2 and #4 cylinders). The wire from # 2 coil pack goes to #3 spark plug, and the wire from #4 coil pack goes to #1 spark plug.

Now the 2.7 Lit V6 requires you remove the surge tank (intake manifold) in order to access the spark plugs & wires on Bank 1 (Right Hand side of the engine).

If someone put anitfreeze where the transmission fluid goes will i need 2 replace the whole engine?


No. your problem is in the transmission not your engine, flush transmission fluid and put new fluid is good idea to change the filter too. good luck.

Have a 2004 hyndia sonata just repaced fuel filter after engine light came on..worked fine for 1 day now engine light back on and runs rough at times doesnt start right away


You are describing low fuel pressure (fuel pump) problem. When you say you replaced the fuel filter, where did you find this filter on the 2004 Sonata? The problem, there is no Fuel Filter, per se, there is a 'SOCK' at the bottom of the fuel pump assembly which serves as a filter, inside the fuel tank. By the way, you mentioned the Check Engine Light came on. Did you scan for any codes in the computer (ECU)? If you did, what were the codes?

Does the 04 sonata really have a fuel filter?


Hi, the fuel filter is by the front of the gas tank. but the person was right about the strainer on the fuel pump but that is just the first filter to keep large sediments out, and secondary filter is to keep the small stuff out.

2004 Hyundai Sonata Malfunction Indicator light comes on and stays on. The car will start but only stays running about 3 seconds and cuts off. I tried putting gas in thinking the gauge might be inaccurate,...


It sounds like you need a new fuel filter. if that is to dirty, it wont allow the correct amount of full to be pushed to the engine. try changing that or using a Fuel treatment in the meantime. Hope this helps :)
