molar? You put a tooth in there?? If you have a mopar crank sensor...... then you have either a wiring problem, (which aren't always easy to find...) or, your pcm is freaking out.

 

I have two pcm both doing same thing and the spelling is my phone try to fix it lol

 

Is the Molar crank sensor new?

 

A bad coolant temp sensor can cause knocking where you can't figure out what is causing it.

I don't mean to say its your specific problem, but it is a major cause of unexplained knock.

A bad cam or crank sensor usually just a shuts the truck down.

 

Now that u say that I did replace it with a cheap one I check them when I get home is there a way to test them I have two

 

Yes it was new

 

If you have a scanner, see what temp your engine things it is, and compare that to the in-dash gauge, and what you think it SHOULD be. (one of your sensors is for the PCM to read engine temp, the other, which also goes thru the PCM....... is for the PCM to drive the gauge in the dash.)

Most parts stores have scanners that should be able to read the data.

 

I see no mention about the cat.

 

Ok I check that with my snap on mt2500 and the cat it fine and would not cause it to knock and carrie on like that I had one go bad already

 

I dont have a mt2500, how do you check the cat with it?
