well brewski he did origionally say

Replaced the mass air flow and cam shaft sensors. Replaced all 4 fuel injectors and it has a new vaporizer on it. I have no other vacuum leaks. It's throwing the camshaft code but it's fine all my voltage check are in specs.

but he didn't actually specifiy the code number so we can only assume it is the E28 code.
Now in some cases i've witnessed that even though the sensor is replaced the code is persistant till it is cleared via the diagnostic program or possibly can be cleared by using the 'pedal dance' or disconnecting the battery for a period of time.
In either case the engine will still run with a bad sensor, it will just be put into limp mode and turn on the MIL light once the code is picked up after a preset period of time when the ECM checks the circuit.
Now the only question that remains in my mind is did he use an aftermarket sensor? TVH?
I've had bad luck with these in the past and the only viable replacement is an OEM sensor.
Could this cause a miss? I personally have never seen it but i suppose it is possible given the function of this sensor.
