Like the title says, I have been having a misfire, a good spark, a fouling of spark plugs and lastly even some detonation on certain sparkplugs. I have changed wires, spark plugs (twice due to fouling and detonating), o2 sensors, Pcms, got injectors cleaned and even got coils! I am now thinking it might be a crank sensor (crossing my fingers AGAIN!!). So I pulled my CPS out and now I want to check and see if it works, so how do I do that, I have a volt meter so if you know let me know exactly how. I would appreciate it, THANKS

 

I'd try a CASE learn on it first.

If either the cam or crank sensor are bad they should be throwing codes...

 

thats the thing, im not throwing any codes!

its getting really frustrating not being able to diagnose this problem!

anyone else?

 

Would any of those 2 sensors cause my symptoms?

Anyone?

 

Anyone?

I changed the crank and o2 sensors with the same results!
