Had a few thing happening since new 408 TT install a week or so ago.

Have tach cutting in and out intermittently. No idea why.
Had some po 300 random misfire guess from new cam and today turned it off.

Also today was checking my dtc and saw three cam position sensor codes saying something like pending immature? We did have a bit of problem plugging the cam sensor in. Buddy said he got it but mabye bent or broke a pin? Had my scanmaster on the car and it didn't show any codes for the cam sensor yet.
Car seems to start ok. the tach is weird as said and it does stall once in awhile for no apparent reason but always starts and usually pretty quickly.

So hearing the cam sensor just helps the car start. Does it also affect how the car runs the fuel or spark ,does it make the car go to like a limp home mode..what exactly does it do in our ls1s?

Also its pain to get to have to remove intake manifold to get to it.Might as well pull it out and look at it and sure can't do that in the car.
