1999 Acura TL Repair Question
Trouble code P0505, massive engine pinging after timing belt change
A faulty knock sensor should through as code, but check it anyway. i would get the IAC valve cleaned what grade fuel are you using? make sure that the tensioner is ok, check for any vacuum leaks, i would get the code sorted first, start here and let me know what you find.
I use premium fuel. I took the car for a drive and now I get p1399 code. I forgot to mention I installed this kit http://www.outlawengineering.com/hondajframe.html from acura forums a lot said this helped with the egr carbon buildup problem. I may take it off and see if my problem goes away. Anyway I searched for possible vacuum leaks to include spraying intake cleaner around the throttle body and intake doesn't seem to be any issue there. My next step is going to be checking my timing belt and make sure the timing is still correct. My new trouble code doesn't indicate which cylinder is misfiring. Thanks for help!!
I checked the timing belt and the camshaft sprocket on the front side of the engine seems to be off by a tooth. Not sure how that happened. The crankshaft pulley and other camshaft close to the firewall are dead on. I'm going to start taking the thing apart again and realign the timing belt. Hopefully I didn't cause any valve damage!!!!
One tooth out should not be a concern, re set the valve timing and let me know how it goes.
So just being off one tooth could cause the excessive pinging???
I feel that it will not cause the excessive pinging, but to continue with any diagnosis the valve timing must be correct, also depending on which cam and if it is advanced or retarded may also have some bearing, get this sorted first, check the knock sensor, clear all codes and re road test.
