Hello I have a P0304 code in my 2000 Celica GT. The car was hesitating and no power when at low speed. I decided to change all plugs and coils. After the change, the car is in the same conditions. I pluged in the computer and still same code P0304, plus another one that read System too lean. What should I do now?

Hi...
On your Celica.
Check if the Strut is NOT bent.
Or if the car was not involved on accidente on the front.
Check the Comdittion of the Lower Ball joint, LOwer control arm.

Check if the Camber in your car is adjustable.
Removing the Tire and removing the Bolt that hold the Strut in position. If the Holes in the Strut are Like Oval, is adjustable.
But if NOT. Some Autoparts SELL a Camber kit. That include
New bolt and washers.

But if you Don't want to spend money on the KIT.
Remove the Tire , Remove the 2 Bolt that hold the Strut.
And make the Holes A little oval the holes .
Move a little at front and rear. For make the strut adjustable.
POSITIVE or NEGATIVE..

Ok I hope this help on your problem...
Thank you for use fixya,,,,,,

Start the car in a DARK place and open the hood. Look for sparks jumping from the plug wires. If you see ANY sparking, replace the WIRES.Have it put on a code checker.
Don't bother going to web sites where you have to sign up for offers or buy anything,

SOURCE: how do you change a rear main oil seal in a 2000 toyota celica gt

First of all, be certain that the leak is in fact from that seal. many leaks travel to that area.

To change the seal is fairly involved, you need to pull the trans and flywheel. There are some specialzed tools involved. Do you have manual or automatic? Manual requires clutch plate alignment on re assembly, by the way , if manual, be sure to change the release bearing and pilot bearing at minimum. Commonly it would make sense to change the clutch during this process....you're already all the way in there..

How can i fix the missfire on a cylinder toyota corolla 2000 1.8ltr


First you need to retrieve codes from the Engine control module. You can buy a cheap code retriever at harbor freight and get the codes. After you get the codes, if it is P0301 it means cyl #1, P0302 = cyl #2, P0303=cyl 3 and P0304= cyl 4. For ex: if you got P0301 you should remove the ignition coil #1(near the front of the engine, where the pulley is) and change its position with the coil # 2. Also remove the spark plug #1 and change the position with the spark plug #4. Clear the codes and start and run the engine until the check engine light goes on. Check for codes and see if the code change for a different code. If it change the position observe which one is the change. If is P0304 you have a bad spark plug, If it is P0302 you have a bad coil. If it repeat P0301, you have either a low compression, bad injector/connector, bad intake gasket them you should continue your diagnostic. I hope this help you.

1999 Lexus GS300. Car is hesitating and can barely pick up speed no matter how hard I press the gas.


it sounds like it could either be a throttle positioning sensor failing, or possibly a fuel injector line could be loose which will cause air into the fuel system and cuase low power and hesitation,,

Lincoln navigator 2000 p304 code misfire changed coil and plugs still havin same problem


Hello puma...i think you mean a P0304 code?

A P0304 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #4.
You have covered a couple of the possible causes...here is the list of possible causes that you can use to continue you troubleshooting...Make sure that you CLEAR the code after each repair is made. The fuel injector would be the next i would check, it could be dirty, defective and not firing. The color/condition of the #4 spark plug would give you an idea. Hope this helps...

Got a p0304 code come up on my 2002 olds Bravada, replaced camshaft and it still didnt fixed it?


P0304 Code - Cylinder #4 Misfire Detected
A P0304 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #4.

Symptoms may include:
* the engine may be harder to start
* the engine may stumble / stumble, and/or hesitate
* other symptoms may also be present

Causes: A code P0304 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.


Hope helps.
