Hello all. This would be my first posting here. I will make the long story short. About one week ago i got a ses code P0303. Had it checked at the mechanincs and they said there was no problem. Just today the engine started acting really weired.. the engine is shaking like i am driving through speed bumps and throwing p0303 code all the time. i know its definately missfire. took it to the same mechanincs again.. they are telling me i need to change the spark plugs. My car has 70k mil. and i dont it the spark plugs were never changed. So I will get the spark plugs and the wires changed tomorrow. The labor fee they are asking is $178 to do that. How hard is it to change them... does anybody have any good instruction to do so.
Also what do you guys think about the problem... i know its definately missfire... the car has very rough idle now... and constantly shaking.
i kinda lost my trust on those mechanics coz they told me last week the spark plugs are fine and now they are saying go change the spark plugs.
thanks
