What Is This Clicking / Ratteling

I have a 2000 Z24 with 42k miles on it...I just bought it and whenever I accelerate i hear a clicking from the car any idea's what it is.. And when I bought the car it had a new motor mount on the passenger side. any feedback would be great and i ca answer some questions hopefully

It could be a bad CV joint

it doesn't do it when i turn. and it's an automatic and it was lowered when i bought it

could be the steering cause i also have a 2000 z24 did the same thing and the dealer fixed some steering components and it went away

i have a 2000 sunfire gt, and experienced the exact same problem just before i broke a con rod at 120 km/h. may not bre the same thing, but i'd have it checked out. oh ya, it had 39,900 km on it at the time.

Spark knock. Use higher octane fuel.

i have the same exact problem, but it happens after i let the foot off the gas, when i accelerate, you can't hear it

or maybe it does make that sound while accelerating, that annoying rattling sound

Spark knock. Use higher octane fuel.

not quite sure if that would solve it, i'll try though when i remember

Im getting the same problem with my Sunfire. Did you find out what the problem was?

Im getting the same problem with my Sunfire. Did you find out what the problem was?Check the serpintine belt tensioner,it may be broken or frooze up. also if the spark plugs or wires are loose it could make a ratteling like a bad rocker arm and not cause a noticable proformance change. :banghead:

i have same problem on my 99 cavalier. im pretty sure my problem is a collapsed lifter. it clicks when i accelerate. mite want to see if thats ur problem. did u run it low on oil?
