so i recently had the codes p0300-304 come up.

so i replaced spark plugs, and ignition coils.

still getting a code thrown at me. every time im at a dead stop, it feels like the car wants to bog down. i would rev a little, and it will drop down to 6-7 hundred them approach back to a grand.

any help? need more info just ask. trying to get this fixed. thanks guys.

 

Do a compression test. If its good then mayb u need a valve adjustment. If not then do a leakdown test. Good luck.

 

thank you very much.

 

Wouldn't hurt to run some good injector cleaner too.
