2001 Toyota Camry Q&A
2001 Toyota Camry Question: I got the code P0303 and P0300,P0301,P0302 old code.Engine misfire at idle.
If you want to FIX this, replace the complete vave cover gasket 'SET'. Oil that has leaked in around the spark plugs will cause these misfires/codes. Replace plugs and wires! Toyota's really work well with "NGK" plugs and plug wire sets! And vice versa!! - pushrod
