I think maybe boost leak from giving it the beans.

Reflash and tighten your pipes. Give us a report.

Skipping a tooth on a chain would be very hard. You would have to have sheared a tooth on a gear. Sorry to hear Blasirl keep up us to date. A compression test may yield if the timing is jacked. You could be ticking because the ecu knows the equipment sensing the timing is off.

Is the 1.4 an interference engine? Hope you get this resolved bud.

What about the cam solenoid/phasers? How does the ECU know what position they are at? Maybe if there is a feed back circuit for those you may have one going bad? But the ticking could be part of the tensioner assembly or just a chain with a bad roller somewhere. Is there any sort of rhythm to the ticking?

Did you dig into the repair yet?

Sometimes you just have to risk it. A good beater car is highly underrated to have around. Hope he's getting it fixed up.

I would change the exhaust cam shaft position sensor. If it is reporting back incorrectly it will cause it to run like dookie. The 420 code is probably a result of the cam being out of phase from where it is supposed to be.

Ecu commands 30°
Actuator moves normal commanded amount.
CPS says hey actuator you didnt get there or you moved to much because its fubar.
Ecu tries to correct
Making car run like crap.
This correction happens constantly.
Just like a servo on CNC.

Let us know what happens.
I think your onto it though.

Or... the camshaft position sensor is fine and the cam is not physically moving as it should and it's being reported its not.
