I have a 2006 RSX-S that I bought a while ago with an overheated engine. Well, everything was warped from the previous owner continuing to drive it as it overheated, so I just kept some of the bolt ons and junked the old motor.

I came across a K20A2 bottom and and a K20Z1 top end, separately for sale, so I picked them up. I freshened up both the head and the block with all OEM parts and dropped it in.

I dealt with DTC P0341 for a while until I went ahead and bought a new OEM VTC actuator and re-timed the motor. Well, now I have 2 more DTCs - P2279 and P0507. I understand that both can be the cause of a vacuum leak, so I went ahead and built a smoke tester today.

I was really excited to find my leak and finally get to drive my car until I put the smoke into the motor and didn’t see it leaking out anywhere. I also tried doing the idle relearn procedure with no luck. The car idles just below 2,000 RPMs and doesn’t ever go down to normal. It’ll also idle hunt every once in a while, but it’s not constant.

Any ideas as to what I can do next? This car is going to end up putting me over the edge!

Thanks in advance!
