3.4L What are symptoms of bad Crank Position Sensor?
 

My 95 Camaro 3.4L is running like s**t and it will not go very fast when I take off, it will take a min or so to get up to like 30 MPH. Just did full tune up but I haven't gotten the coils tested but they all spark. I cut the exhaust off because it was clogged, I know that takes away the back pressure and would cause a little lag but this car won't even go over 80 MPH. Help please, I have a 96Z28 and I need to catch up on my 3.4L knowledge lol. I need symptoms of bad crank position sensor and how to test them.

I've had two go out on my 94 3.4L. Just one day in the winter it didn't start. Never noticed any problems other than that. But like I said, I had two go out in the 2 years I had it.

Well I was also thinking clogged converter but what are the symptoms of that. I think I need to get the coils tested and then change the CPT sensors.

It has a loss of power on both bottom and top end, it hesitates, vibrates, shudders
