P0130 sounds like an O2 sensor code.

Thank you for responding, do you know about how much it would cost to repair them??

That's what the link to the other thread was for.

Sometimes you get a ghost error code of 0325 when you have another problem. The best thing to do is to test your knock sensor for the correct resistance. Do you have a digital ohm meter? There are write ups on how to test this, but if you like I can walk you through on testing it out.

Also, $800 is entirely too much money to spend for either or both of these sensors. The KS goes for $177 with any mechanic or auto store. However, there is a store on Ebay that is selling them for $65 shipped. I bought one of these and they are the OEM switch so no need to worry about quality. The Infiniti/Nissan service manual says that you have to lift the intake manifold and replace all the gaskets. But a person with nimble hands could replace the switch without too much difficulty. Sometimes, it pays or rather saves to do the work yourself. I would really recommend doing the work yourself on this one, that is, if you are mechanically inclined. If you have a decent mechanic do this operation, you are looking at around $500.

As for the Oxygen Sensor, if the computer says its busted than more than likely it really is busted. You should replace this and you should pay the price for a new one.
