I just replaced my radiator. When I started it up and backed it out everything was just fine. Once the car reached operating temperature the SES light came on and I pulled a code 36. The car starts up, idles, and runs fine. The only things I notice while driving is detonation at highway speeds at 1/2 or more throttle. If I accelerate from a stop at 1/2 throttle or more, I can also feel the power fall off after a couple seconds. It feels almost like it's pulling timing out, and then I can feel a miss.

Obviously I had to take the MAF off to R2 the radiator, so that got disconnected, but it's plugged in, and everything looks fine.

I've searched this code and I think I need to check into the MAF burn-off and power relay, but I'm not 100% sure where they are. Can someone point them out to me?

Any other suggestions to fix this problem?
