Hello and thank you for using JustAnswer.com
What brand plugs, and where did you get the coils?
i cant remember come from autozone
Well, the plugs need to be NGK spark plugs.
As far as the coils, you need to use factory coils. After Market ones never work.
I have been dealing with the P1320 code since 95 and and the only thing I have found that repairs it
is replacing all 6 coils with factory coils.
where do u get factory coils
If your use after market coils the internal resistances are not the same as factory
You would need to get them from the dealer
ok what about the 0340 code
That is a cam sensor code
yes it is
So that may require the cam sensor to be replaced.
where is it located
but also, do not get this sensor after market
Front timing cover. One second I will get you a image of it's location.
