Check engine light is faulty or that the engine computer has run a diagnostic check and one of the systems failed. You can use the diagnostic tool http://www.xcardiag.com/search/?q=+code+p0650 hope it can help you.

Describe the noise

This is usually a low airflow indicator for the air intake into the engine. There is an airflow sensor that may be faulty. Also, when was the last time you changed your air filter?

may have to replace the transmission shift solenoids. Some google searching will give you the best idea on what you are looking at. Those parts are always cheaper on ebay. (thats where I get mine)

Some vehichles have a warning bell for turn signals being left on, trunk lids left open or seat belt sensor could be un-plugged. Think outside the box, you may find it. Good luck:)

Sounds like it's either a coil pack or an injector to me, try switching the number four coil pack with any of the other coil packs if the miss follows the coil pack you need to replace that coil pack. if not it's either a fuel injector or a mechanical problem inside the motor, I would rent noid lights from a local auto parts store and look for injector pulse in the cylinder with a misfire, if the noid light is flashing it may be better to leave it to a professional as it is likely internal engine damage. hope that helps. chris

All four cylinders should have over 100 #'s of pressure-ideally over 150#'s-and they should be even or close to even. You could take off the timing belt cover and check the timing, but it sounds like 2 bad cylinders-which could be a valve train problem.

Next time buy a manual car and be a real macho man P0700 Transmission Control System P0733 Gear 3 Incorrect Ratio And next time you go to autozone dont pay them unless they give you the code definition

You think it is in park but it read reverse because it didn't move With electronic transmissions you have to run the fault codes to find what is happening. Unless it is in park or neutral then nothing concerning the starter will work. If the TCM is faulty then servos/solenoids are not working and there will be no clutch pack or band operation and it will appear in park. Even the torque converter clutch will not be working and you will get nothing in the transmission.

be looking at fuseable links in the wiring and connectors also.. I just had this issue myself..mine was a bad connection on the alternator..which is unfortunately locaded low near the passenger front tire.. it always gets wet during rain or melting snow/ice conditions..my car is a 91 and its missing all the plastic splash guards under the front..I took the alternator off and got it tested ..it was fine.. my wiring harness has 4 connectors made into a loom that fits on the back of the unit..one of these was all rusted and I wire brushed it and coated it with waterproof grease.. it works just fine now..the fuseable links are wires made into the harness that will burn apart instead of the entire set burning up..and destroying the car..these links will feel wierd if the are bad..and will bend very easily when they are warm.. if one is burnt through it will wigghle easily also..

Check coil

Replace all the plugs and the coils on the cylinders that are not firing.

Most likely squirters are plugged off by build up which is pretty common. Other problem could just be a weak pump

i would change all the air filter(s) and valve filters on the engine. make sure none of these are clogged-hoses and such. bad air flow will cause this type of problem. If you need further help, reach me via phone at https://www.6ya.com/expert/ray_6d6dc1dfa6f18dc1

Sounds like a blown fuse

Interesting!... Did you bend the hood when you took the battery out? Here's a possible cause. On the right hand side of the engine compartment is a hood switch (part of the burglar alarm system.. here's a pic)
On the underside of the hood is a rubber button which depresses this switch when you close the hood. If it's missing, then the switch is not being depressed all the way (and can cause the symptom you are experiencing). OR, you bent the hood and the rubber button on the underside of the hood is not pushing the switch all the way down (a wind gust can lift the hood just enough to activate this switch) which sets off the alarm. Hope this helps.

It's a 08 Elantra it is not much involved. The heater looks like a spark plug socket that has outside threads on one end ( the working end ). The other end is shaped as a bolt.There are three (3) freeze plugs along the side of the engine that faces the front of the car. They run a straight line and are about 8in. below the level of the head and all are behind the exhaust manifold. You can barely see the edge of the first one and last one if you look closely around and beneath the edges of the exhaust manifold anyway.

You can access that here www.alldatadoy.com, we however do not have the information here at fixya.

the transmission wont shift gears

Follow this steps on how you can replace the thermostat. First,Remove the radiator hose from the thermostat housing cover by removing the bandclamp that holds the hose to the cover. This is done with a Phillipsscrewdriver. Slide the band clamp back away from the housing and pull the hoseoff. Remove the two bolts that hold the thermostat housing cover to the top ofthe Elantra intake manifold with an adjustable wrench. The bolts will bereused. They should not be discarded. Remove the old gasket that was pressed between the intake manifoldand the thermostat housing cover. It's a paper gasket and should pull off ofthe intake in one piece. Remove the thermostat from inside of the intakemanifold by pulling up on it. The gasket and thermostat can be discarded. Placethe new thermostat into the intake manifold of the Hyundai Elantra. Thethermostat must be placed with the top sticking out of the intake manifold forit to work properly. Use the old thermostat to orientate the new one. Place a small amount of PVC gasket sealer around the thermostat onthe base of the intake manifold. Allow the PVC to dry for ten minutes and thenplace the thermostat gasket on top of the gasket sealer. Place a small amountof PVC gasket sealer on top of the paper gasket and allow to dry for tenminutes. Place the thermostat housing cover onto the gasket and bolt it intoplace with the original bolts. You should see a small amount of PVC gasketsealer squeeze out between the housing and the intake. This is normal and itshould be left in place. Once it dries, it will add additional seal protectionand prevent leaking. Place the radiator hose back on to the thermostat housing cover andfix it into place by tightening the band clamp with a screw driver. YourHyundai Elantra is now ready to drive again. Hope this info help you.
