Clicking when I floor it

[casey]

I have an 89 240 SX and when I floor it, it makes this weird clicking noise. Does anyone know what this is?,

Thanks,

could be an exhaust leak....does it kinda do it when your in the upper gears, low rpms, and go heavy on the throttle too? like its coming from underneath you?

Yeah, but it is comming from in front of me towards the floor

my honda did that.i think its just becouse it cant create the power becouse the mixture is lean. at the low revs and in the high gears.its kinda like bogging out.

if your car is an auto then there is a swich to down gear the transmission when u floor it... i know mine has that.. kinda nifty.. when the car is off press the gas all the way down and see if it clicks..

Sounds like bb's hitting a coffee can? If so, that's mild knocking. Try using 91 or 93 octane.

Sounds like exhaust leak? Does the problem persist after the car heats up? Check where the manifold bolts up to the block I've noticed most Ka's ive had are usually missing some of these bolts causing exhaust leaks. If the sounds stop after the engine warms up probably cause its hot enough that the metal expands and closes the leak. That's my best guess. If not might be ticking lifters or sticky valves. Various things, but should just go around checking everything is bolted on oil level is good and clean and all that stuff.

BB's in a coffee can? It might be detonating.
