After replacing all sensors, determined that the camshafts had rotated since they were pressed on. Followed TSB and also a very thorough path to replace them. Triple checked the timing marks and they are perfect.
Started car and all codes went away but after about a minute, it shuts off with a P0303.
The car runs rough during the period but gets a little smoother at higher rpm.
No codes are set except for the P0303. The previous codes did not set again.
Changed all spark plugs and swapped coil but the P0303 remains. Firing order is 1-3-4-2, so I made sure to swap cylinder 4 and cylinder 3 coil to make cover all bases.
I was unable to do a compression test because of a bad tester but the car ran fine for 10,000 miles.
There is no apparent head damage, coolant and oil are clean for 10,000 miles after the original timing chain replacement.
have the same problem?
