Hi, Bob And Ken:
I have a Toyata Camry 2001 LE, 61,000 miles, I got an "Engine light on" proglem months ago and drove to Toyata Auto Malls, found code P0300, P0304 and replaced spark plugs and wires, but the car stalled out while driving home after picking up, towed back and replaced idle control valve, it worked fine for months and then the engine light turned on again, this time found code P0446 and replaced Faulty CCU Valve, OK again for just 2 weeks, the engine light turned on again! The agent said they only guarantee what they replaced but I do not know what I need do about my car. I appreciate your kind help in advance. Guoxian

There is no indication the dealer did anything wrong, except possibly missing a bad idle control valve on the first visit. Replacing the spark plugs and wires is standard practice for misfire codes (P0300, P0304), especially when they are overdue.

I recommend going to Advance Auto or Autozone and have the trouble codes read (free service).

Post back here with the trouble codes and we'll offer advice on how to proceed. Sometimes it's a repair you can do yourself. At the least we can offer you peace of mind on what to expect at the dealer.

FYI- The clerk at the auto parts store is not generally qualified to give repair advice for trouble codes. Please let us know alphanumeric trouble code(s) they find.
