Is my timing off?

04gtdrop · May 15, 2006

ok, so i got on the throttle the other night on the way home. Its a country road out here and so i wanted to go WOT jsut for kicks. Anyways, i started to hear a rattle-tick around 4k-5.5k or so in 4th gear, i dont think i was making that noise in any other gear. Is it possible that my timming is off? how do i use my predator to fix it? and why is this happening now? i have been WOT many other times and have not heard it before. why now? what else could it be?

if you need any other info let me know and i'll post it up....

could be many things. bad gas for one. your timing should be what it always was before since it's electronically controlled.

thats what i was thinking, the computer controls it, so i was thinking maybe it changed it a little or i was thinking bad gas, but i always use the same brand of gas. hmmm, i just dont want to damage my daily driver....

any other ideas?

CAI, stock MAF, 70mm T/B, trick flow plenum, mac pro chamber with cats, mac cat back, Aluminum drive shaft, 3.73's and a diablo predator with a custom tune.

your custom tune might have to much advance or not enough fuel...

a wideband 02 would tell you. or you can see if it goes away if you use the stock tune.
