I've been working on my 97 grand prix gtp for a couple months now and almost have it fully running but I need to change my camshaft position sensor. Here's the thing I recently changed the sensor out but when I started the engine it had some random misfires and the check engine light started to flash! Now I am wondering if I need to relearn the camshaft position sensor in order to stop the random misfires. Has anyone else ran into this problem and if so did you need to relearn the camshaft position sensor or was there something else? Any help is appreciated! Thanks!
