With all joking aside I have a story of irony. The other day I was looking through the new posts and read about some guy who had an engine knock and fixed it with replacing an air intake charge sensor. Then go figure two days later I notice my 03 GT started to knock. It only does it when I shift somewhat firm. If I slip the clutch no problem. When I just run through the gears it will knock 2 or 3 times real fast just as I shift. I didnt change anything recently. only mods are K&N and MAC cat back. So now it seems simple right? Change the sensor. But im not convinced thats what it is. I tried to find the post and re-read the symptoms to see if they match but i cant find it. Its only when the engine is warm reguardless of outside temp. Anyone remember this post? Advice. Thanks.
