Car runs weak, low power

There are a number of things that can cause low power. However, I just want to make sure you cleaned the throttle body after this started to try and address it? Sometimes that causes this issue so we just need to make sure that was the correct progression.

Next here are some guides that take us through this issue. We need to start with this and make sure none of these issues are causing this.

Then we can move onto the next thing which is a possible throttle position sensor. However, there are normally codes with this so when this happens is there a light that comes on or does it just feel like it is low on power? If there is no light then a throttle position sensor would not make sense and it would be more like a mass air flow sensor.

Here are some guides that talk about this:

Let me know about this and we can go from there. Thanks

Okay. I suspect what happened is after you cleaned the throttle body, the P0507 set with the raised RPM's which is why it felt better. Then after it learned the new throttle position after it was cleaned it returned to the low power.

I suspect you have a vacuum leak. Take a look at this leak and let's check for a leak and go from there.

Yeah. I am pretty sure this is a vacuum leak. This is the same guide that I posted earlier. Take a look at it and get some parts cleaner and spray it around the engine while it is running. When the RPM jumps up then that is where the leak is.

As for the oil leak and pressure sensor. You will need to replace it if it is leaking. However, we need to get a new post started for that as it is not related to this one and we need to keep each post to the one topic so that others can find the solutions if they have the same issue.

Let me know what questions you have about this vacuum leak and we can dig deeper. Also, here is a video that shows the same type of info and it may be a little easier to follow:

The only difference is, you don't have the high pitched noise. You will just hear the RPM go up when it pulls in the fluid.

You are welcome. Please let us know what happens as I am curious to see if this was the issue. Thanks
