After overheating, my son's 2009 Honda Civic LX was showing the following error codes: P0303. P0304, P0300, P0353, C1555. I noticed that some of the ignition coils were warped (really hard to get out). I put new plugs and coils in all 4 cylinders. I reset the codes but the same errors code remained. I'm not sure what my next steps should be. Replace the ignition wires? Any suggestion would be greatly appreciated.

 

• air in radiator (bleed radiator fluid)
• Check distributor cap and rotor (make sure gasket is properly set before reinstall!!)
• do compression test ( I personally pull the fuse for the fuel pump) Piston rings come to mind when cars overheat
• check injectors for cracks ( the little piece that goes into heads
• vacuum leak

Start with intake hose, me personally I take out all hose that leak into intake manifold and mark each hose with a specific mark to its correct place (tape each end of hose and tape off the part of intake manifold and make with diff color marker or something like (,(,$,&,@ ect then match hose to correct symbols) bend the hoses to see if there is any cracks and holes and then move on to Throttle body turn car on and start spraying throttle body cleaner around the gaskets then move on to intake manifold gasket (do not spray directly on the part spray from 12-16 inches away throttle body cleaner is flammable so do not soak parts and please be careful) i will not be held responsible for any injuries or damage caused to car or humans
