Hi
I have 02 Galant 4cyl ES..lately it has problem with start the after 1st start..
I went to Autozone..code came on P0340 and P0303..
I would like to know if I fix P0303 cylinder 3 misfire.. Will P0340 go away or there are 2 totally diff problems?
should I replace spark plug wires and plugs? do I need distributor? or cap?
thanks
Your P0340 is a different problem from your P0303, but they may be related.
Since the code P0340 indicates that there is something wrong with your cam speed sensor, your misfiring in cyl3 may be caused by this.
This points to addressing the P0340 error before the P0303 since it could be contributing to the 303 in the first place. Look at your cam speed sensor in cyl3 and maybe this would solve both problems at once.
Hope this helps.
