Water on the spark plug wires will do this, especially if your car has a distributor that is not solid state. Water gets inside the distributor cap of the older vehicles and shorts the spark to other cylinders than the ones intended which causes the rough running.To push the water off the wires and out of a distributor cap, spray WD-40 anywhere you do not want the water so you can run the vehicle. Be very careful if you do this inside an older cars distributor cap since The WD-40 will also break down the bearing lubricant down the shaft. Use this in an emergency to get you home etc, then see a mechanic to make sure you didn't cause any bearing issues.

Both codes are for major leaks in the Evap system which vents fumes from the gas tank to the engine.Code 455 is for a major leak, and code 457 is for the gas cap which could cause 455.The codes can set if you run the engine with the gas cap off, or there may be a problem with the cap or other component.

Look at your ball jonts There shod be a rubber piec if it is gone then you need new ones

if there are grease fittings present, grease them. if not there is a needle you can buy that will attach to your grease gun to puncture the seal boots on tie rod ends and ball joints to lubricate them

see if the noise is coming from the a/c clutch area it could be going out their are also belt pulleys and tensioners on this system and when a load is on them could be making a noise

Sounds like you have loose brake pad linings.
The traction control measures rotational speed between each rear wheel. If your pad lining momentarily causes one wheel to hesitate your trac control will flash. As the ABS detects braking without the brake pedal being pushed, it will flash.
Check your emergency brake pads. They can fall apart inside the drum/rotor combo on the rear. That is where your sensor is for the ABS.

A code P0302 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer

Possible Solutions:
* If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
* If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Keep us updated.

It may be your heater core going out, but I would check all my fuses to make sure they weren't any of them bad before I started checking anything else. Hope this information is helpful to you.

i may say it came from loose oil drain plug or the oil filter(if it's change). and maybe the technician forgot to torque or put gasket on the plug and tighten the filter.

This will help.

Thanks.

First check for worn sparkplugs and if they still god then check for spark on those cylinders by pulling the sparkplug wire off and cranking the engine over.If there is no spark then replace the coil.If there is spark i would have the injectors leaned.

Bad coil most likely!! Hope this helps good luck!!

bring it to any parts place for free--but codes dont tell the real solution--a scan that runs a data stream targets it

I believe those vehicles have a spade terminal on the starter it has a plastic square covering on it grab it and wiggle it and pull and push it than try to start those connectors get corroded and dirty!
