Ok. They looked alright. One of them had a bit of black gunk but not too bad.

I read somewhere that the cam and crank sensors are on the same circuit. I got the cam error code but could it be the crank sensor instead? Thanks again.

That'* a possibility. Does the tach still drop to zero. IIRC the crank sends the signal to the tachometer.

Thanks for your response. That what I was thinking/hoping. I'm going put a crank sensor in and some new plugs. I got my fingers crossed. I let you know how it goes. Thanks again.

I have a similar situation was to blame sensor (ACDelco 213-151 Crank Position Sensor GM Ref # 10456161).

Hey guys. I was dead set on get the new crank sensor in tonight but I broke 2 extensions trying to get the harmonic balancer bolt out. That thing is really one there. I admit I did try it with 3/8" drives but thats all I had. Tomorrow I will get some beefier 1/2 extensions and have another go at it. Is there some trick to it? I followed the guide; took off the starter and stuck something in the crank so it wouldn't turn. Put a jack under the extension and used part of my weight bench for a cheater bar. Even if I do get it off I'm still not 100% its the crank sensor. I could be in the corner tomorrow, in the fetal position, and crying my eyes out if I can't get this figured out. ;0

You will need a puller with long enough bolts

Yeah, I rented one of those from autozone. They included a bunch of bolts and I think I have the 4" * 1/4" with the fine threads. I just haven't gotten there yet. I have to get the 15/16th bolt off first right? That thing is a nightmare.....

You will need 1/2" extensions and a impact 6 point socket, I forget the size but I have it listed in my write up. https://www.gmforum.com/mechanical-134/harmonic-balancer-replacement-286278/ You will need some PB blaster and I find some heat helps a lot. However, I really don't see a bad crank sensor causing a sputter. That'* typically a bad coil(*), bad wires, or bad plugs. If your getting a P0300 code it'* random and might be the ICM, if you have a P030x code that'* always the same cylinder it'* a coil, wire, plug, injector, bad valve spring or possible chipped piston.

I had an ignition mod. go bad after it got hot. Car kept stalling. It'* the silver box that the three coils sit on and is easy to change too. Just makes sure you get the coils back in the correct spot!
