engine making weird noise

[Andy Cheung]

hi everyone,

last nite, i was driving around 75mph on highway, and then i downshifted to
third gear, shifted to forth BEFORE redline, and then to
fifth........................
after that, the car has been making a weird noise.......................it
sounds like tick,tick,tick,tick....
very noticable during acceleration, u can also hear during idle or warm-up
but not as loud. i did not hear any of that noise when im just cruising on
highway. does that sound like detonation to you guys??? or what could
happened? btw, i have a 92 NX2000 with a DET in it, stock everything except
a 3in downpipe and a 3in cat-back, and a hotshot intercooler kit. i'll look
under the engine today and see if i can find anything.........please
help......thank you~!
