Hmmm, spark knock wouldn't be low on the engine. What you're describing (just GUESSING) would be more like a connecting rod that's loose or misaligned, or crank shaft related bearing.

50K is nothing, you shouldn't be having spark knock unless something isn't right which it sounds like regardless something isn't right.

If you are really having spark knock it is VERY likely your computer has stored some 'misfire' type P codes. I would really check into that with a scanner.

like i said it sounds like a thermostat chatter for the noise but only on hard acceleration. does not do it when engine/tranny is cold or in park/neutral anytime. only when in drive when hammered down you hear this little chatter coming from your feet as if a torqe convertor or something is spinning and is knocking around a little piece of metal because its not syncronized and doesnt keep the same beat as if it were missing or lifters taping. its like a piece of metal is just jumping around in the tranny or engine. i will take it and have them throw a computer on it ad check for codes. but its just so frustrating.

and i agree something isnt right haha

so i ran some 93 threw her from shell...and guess what its not doing it now lol...i heard it maybe once yesterday on a 20 minute drive back and forth from work when my foot went to the floor and now i mean its shifting better and running much faster it seems in all honesty would a chip cause your vehicle to not run correct on certain type of gas or is this just my imagination because i dont hear it any more? i swear i read a post on here about installing a chip or programming you vehicle and it gives you the choice of what gas you wish to tune your truck with...i dunno the difference. but day in and day out im beginning to think think truck is chipped
