ticking sound

[jon2295]

my o4 gp makes a ticking sound under hard acceleration, but only to about 3k rpm then the tick goes away. i only have about 34k miles on it. the only mods are a k&n cone filter replacing the air box

possibly the engine is resonating with some loose part in your car at the specific rpm?

Check your car's octane requirement. Try using a higher octane to eliminate spark knock and induce proper detonation.

may also be something having to do with your AC. Turn your AC off and fan off, and see if that helps. I remember back during the summer in my Grand Am, for some reason when I had the AC on and I would get on it, it would make like a hammering/ticking sound.

i have tried the higher octane but it does not work. could the k&n filter affect the air fuel mixture.it sounds like a bad lifter.

thanks for all input.

Can we find out, what kind of GT is it. GTP or GT. Only happens under accelation?
Ever raised hood and give it a little gas to see if it happens then?
Kind of hard to say enless we have some of the basic information.

Thanks

its a gt and i tried to hear it w/ the hood up but it only does it when it is under a load , when accelerating hard. tried power braking but could not get it to make the noise.

GT's can burn reg. with no troubles.
