95 sonata ive blwn a 2nd coil in a month what could cause that

You have to make sure the brake system is operating properly.Change both rear brakes it sounds like the left rear brake side is not working making the right side wear out so quick.After changing the back brakes bleed them making sure you have no air in your brake lines.start bleeding them from the left rear to the right rear to the left front to right front to master cylinder.

you'll have to see if its missing fuel,air,or spark.Fuel could be bad fuel pump,air something clogging air filter duct,spark bad coil,or coils,crank sensor.

Could possibly be a weak fuel pump.

Need to remove upper intake manifold

You can see the coils on the front or left bank

I'm referring to a V6

1,2,3 right side of motor -next to firewall
4,5,6 left side of motor-next to radiator

If you have a v6 do the 3 coils while your there & intake is off
& save them for some time you need them on the left side


We have no diagrams

A code PO301 thru PO306 does not mean a coil is bad

Watch" Wayne"on Real Fixes Real Fast ---on You Tube

You get the plugs & coils from Rock Auto.Com unless
you like spending more at the parts store

Spark Plugs--every 3 years
O2 Sensors--front ones only--100,000 miles
Gas filter & Air Filter -3 years
Trans & Power Steering Fluids -3 years or failure isn't far away


Try to use th OE Brand Plugs on a ford
The tip configuration etc is important
Because it show ten plugs that fit they may
not work well


I would have the motor checked with professional
scan tool software in Mode #06 & look for cylinder
misfire on a road test of 20 miles,before I did any
of the work your going to do. That may show you some
failing coils. Codes are next to uselss
I have had to walk new coils form one cyl to the next
even when the scanner didn't pick up anything

have the head gasket checked,pretty common on these

well the ring should stay on the oil filter if there was one on there when you took off the old one it came off and dont need it

You didn't specify whether you have the (4) cylinder or the (6) cylinder engine..... I have a 2004 Hyundai Sonata 2.4L 4 cylinder and I just changed the spark plugs in it. I believe that the 2005 2.4L engine is the same. To locate and change the (4) spark plugs on a 2004 Hyundai 2.4L 4 cylinder engine: Remove the (4) 12mm bolts from the decorative plastic engine cover. Remove plastic cover from engine and place it off to the side out of your way. Standing in front of the car, the (4) spark plugs are located laterally (left to right) in the recessed area underneath where the plastic engine cover was removed. Note: This engine has (2) coils....They are located above spark plugs number (2) and (3) from left to right. Starting with the fist spark plug on the left: Remove the spark plug cable by pulling straight up on the insulated connector. Using a spark plug socket, remove the old spark plug and install a new one in it's place. To access the second spark plug from the left, remove the electrical connector and the spark plug cable wire from coil number (1) and then remove the (2) 12mm bolts that secure the coil to the engine. Spark plug number (2) is located directly under the coil. Lift the coil straight up removing the insulated connector from spark plug number (2). Using a spark plug socket, remove old spark and install a new one in it's place. Repeat same procedures for spark plugs number (3) and (4). Note: If you have the (6) cylinder engine, the front (3) sparks pluge are readilly accessible but in order to access the (3) rear spark plugs, you will have to remove the intake manifold

it's under the intake manifold on the rear of the engine

I just did this today. This is how I did it and by no means I am a professional. You will find two 12 mm black bolts along with 3 12 mm zinc bolts on top of manifold these need to be taken out. Next on the left hand backside you will see a ground wire that needs disconnect. Right by this connection you will see another 12mm black bolt on the back side this bolts need taken out. there are two more of these bolts going across the back that holds a wire harness as well as the intake manifold. Next, I took of the flex pipe from air filter and disconnected the wire harness (gray and black) I believe go the air flow meter. this will help you get to the left side back bolt. the middle back bolt is right under the trottle cable brackets. I moved my cables being carefully not to move the 12 mm nuts to much. Next I took the bracket off which gave me room to get to the bolt. The manifold should be free to move now. be carefull and gentle when moving to look for any connection that might impede moving the manifold to the right side(brake fluid tank side) this will give you enough room to change all three plugs. Took me a couple of hours to do.

sounds like the governer gear stripped out , its located on the driver side on the trans where the axle inboard shaft goes into the trans
