Sounds like timing is off to me Chris, check your timing with a timing light then report back...

So here is where i at first time i checked codes i had a 12 and 14, put in new crank and cam sensors.
clear the codes, then the car goes back into limb mode, check codes and get a 24 and 41, found the short and fixed it. go to drive the car it does ok but goes back into limb mode check codes and get 24 and 52 so strip the harness and find the wire to pin 6 on the w clip is not connected to any thing.and find about, three other wires not connected to anything. anybody have a reference of the wiring diagrams so i can check the whole wiring on this car. And exactly where knock sensor 1 is.

Knock sensor is under the intake manifold towards the front of the engine. Up and more towards the rear than the oil pressure sensor and is taped(or supposed to be) to the wiring for the knock sensor. Single wire plug,

Pictures of the said wires and locations might help as well.

will post pics of the lose wires, but the location is the wire harness.

 

[sp617m]

The first pic there are two sets of wires that look like that with the brown wire broken. the last two are of the same wire on the w clip whic i think are the knock sensor one pin out.

Have rewired the front knock sensor and still the same thing reving to 3k and falling off and back to reving if i let go of gas pedal and code 52 still pops up. Any help would be appreciated thank you.
