My girlfriend has a 2002 Lancer ES with the 4G94 engine. I just replaced the head due to her snapping the timing belt and bending every intake valve. Well now the service engine soon light is on and it's reading three things. Cranshaft position sensor (which was risky to begin with because when I reinstalled the crankshaft pulley the two pins in the lower timing gear snapped off and the reluctor wheel that tells the crankshaft position sensor which cylinder to fire on was worn away because the belt snapped and took the teeth with it), camshaft position sensor (which I was wondering if this is throwing this code because of the CKP), and cylinder 4 misfire. I'm believing the cylinder 4 misfire is because of the CKP. But I was wondering if anyone else was having this problem because there is a service bulletin posted on Alldata about the camshaft position sensor. Any help is greatly appreciated. Thanks in advance!!!
