Today I changed my timing belt on my 99 acura tl. I have done this job before with success. This engine is also notorious for having excessive carbon build up in the egr system so I cleaned that as well. I took off the throttle body and upper intake and it was almost plugged closed. After putting everything back together (I checked the timing marks numerous times) I started the car. I let the car get up to operating temp. Still running fine. I took it for a drive and as soon as I stepped on the gas the car starting pinging very loud. I went back to the garage and when I pulled in the check engine light came on. I ran the code with my scanner and came up P0505 Idle Air Control sensor. This sensor doesn't indicate the solution to my problem. I'm gonna start tomorrow by checking the timing marks AGAIN and making sure my knock sensor didn't unhooked somehow. If you have any other suggestions that would be great because I'm sort of clueless to the problem.
