Tune.....Spark knock

[beeper]

I was driving with the radio off and the window down today and I noticed a pretty loud spark knock. It only happends when I take my foot off the accelerater to slow (like making a turn) then give it a good amount of gas again. If I only give it light gas it wont do it, also it will not do it straight out the hole. The speed does not matter, I could be turning or on the freeway. Off the gas and back on causes big (about a half second) spark knock. Thanks......Pat. BTW I have a custom tune loaded in my car by a rep. person from this site also I'm not sure if it has always been there or just started. I also put on a k&n filter 3weeks ago, the tune has been in for 3 months.

Have you tried taking off the tune and driving it to see if it makes the same noise?

It can be adjusted anyway so I wouldn't worry about it. Just talk to whoever tuned it and I bet they will work it out.

Contact your custom tuner, they would be the one to correct your problem.
