1999 Plymouth Neon 4 cyl Front Wheel Drive Automatic 136000 miles
The check engine light has been on and off for a couple months now. I have taken it to two mechanics now. Both of them found a code 340, checked the cam and all was good there. The second mechanic found two more codes--123 and 320. He checked what he could and said, again, that the mechanical parts were working.
Is this a computer problem or electrical. Or worse yet, both? I appreciate your help.
