Codes now read random misfire and shows cyl. 1,2,3and 4 misfire. it also has a loud and constant rattling that sounds like the valve train. pulled the valve cover and confirmed oil is flowing. any ideas what to check next ?
You did get the right part ??? Installed and hooked "everything" back up exactly where it went???,You did disconnect battery "before" you worked on it right ??, and in doing so , the computer's brain will norm. take some driving time to adjust itself to the car again and unless you had another system break down , it should clear it self 5-15 miles...by the way ,... what caused the part failure???, do you change oil as recommended ???

I have exactly the same problem and codes you listed on my 2000 Camry 4 cyl. I replaced the plugs which had no effect. My friend mechanic said the problem is deffinitely the wires and I could also need to replace the coil pack.

There is a VSV (vacuum switching valve) , usually mounted on the back side of engine block, under the intake manifold, as well as the map sensor, that can also cause that code if one or the other is faulty. It takes some pretty detailed troubleshooting to confirm this in some cases, so if that's not in your line of work, you may have to have it properly diagnosed, or take a 50/50 shot at which one first.

It could be your spark plugs or a coil. To see if it's a coil move the coil from #5 to #6 the miss will change to that cylinder with code p0306 and change #1 to #3 and see if it changes to p0303. If it does replace all the coils. You change all coil because if one or two go you know the rest are not far behind

all the codes you have are all related to the fuel trim, this problem needs to be looked at with a european capable scanner for futher tests sorry.
