Do you have a code P0300? If the plugs and wires are old you can replace them, but a lot of time I see that code it also can be a vacuum leak. Check all hoses for cracks. Have the engine running too and move things around to find it easier. The idle will go up of down or you will hear hissing.

I don't know what the code was. We are selling the vehicle and a potential buyer used the OBD and told us it said all cylinders were firing. We just replaced the valve cover because of a leak and know that the timing belt cover has a leak as well. We have not replaced that cover. Could it be the timing belt? As I was told the timing belt might be covered in oil, although it is not due for changing for another 60k kms

The fellow said that all four cylinders were firing so I can only assume that all four codes were showing.

Seems we need to know the exact numerical ID of any and all coded set in the computer. When the Engine is running...does it run rough? When driving down the road....does it run rough?

Thank you for your help. I drive a 1999 v6 camry, and in comparison to my car, I think it runs rough, although I don't notice the misfires. It is my brother's car so I only drive it occasionally.

Suggest you have the computers re-Scanned and provide us with the exact ID of the codes. Numbers and letters. Some Auto Parts stores do this for Free.

Guru9k4cp Did you find out what those codes were for. Or maybe I should rephrase my question to ask you if you found out what the problem is because I have a Toyota Camry 2005, 2.2 liters 4 cylinders and I also have those same codes along with a P0172 and a P0136

Babybluz64....lets start fresh. Clear all codes...take it for a ride. How does this vehicle run? Any warning lights on or flashing? Do you smell Gas inside or outside the vehicle? Pull the engine dipstick. Smell the oil on the end of the DS. Does it smell like gasoline?
