I have a stock '02 RSX-S with 93K miles.I recently started hearing a ticking sound coming from the engine while accelerating at low rpm's in any gear (i can hear it at higher rpm's too, but at that point the engine rev starts to cover the noise up). With the windows closed it sounds like it's coming from the center of the engine. It's much more noticeable with the windows open driving next to something (and it's much more noticeable with the passenger side window down than the drive side). Some more hints: -can't hear it while cruising at low speed at low rpm, but as soon as i hit the gas i hear it "tck-tck-tck" -noise dissappears as soon as i let up on the accelerator. I just watched someone put his problem on youtube http://www.youtube.com/watch?v=ndMBFEAQm... the noise are so similar. I just tried to put the the car on neutal, turn off the ac and light, then turn it on. The noise was hard to hear when off, but get louder as soon as I turn them on. Same noise as I hit the gas in gear at the low rpm's I mentioned...Could that be the A/C compressor's bearing? or I need to clean fuel injectors and do a valves adjustment, I heard Honda has the issues... Thanks !!!

Sounds like a loose belt,dirty fuel injectors or fault in ac compressor fan.Clean the radiator fan.Check the engine belt first.If its very old and looks worn out,then replace that belt.Other thing check the fan the radiator fan when its spinning .If its not spinning freely then its the problem.The fan bearing needs to be checked. Other thing to check is the dirty injectors.remove and clean the injectors and refit it and then check. Also the other possibilities to be checked in this case are:--- clicking or ticking sound when accelerating the gas pedal:---- The clicking is being caused by a bad exhaust-manifold gasket, which allows exhaust to escape its normal route from exhaust manifold to pipe to muffler. And in escaping that route, the leak makes noise as often as the piston nearest the leak purges exhaust from the cylinder in which it is operating. Hence a clicking noise that increases in frequency with an increase in RPMs. In some cases noise decreases when RPM rises. Check for loose sparks plugs also, lifters, fuel injectors, fan hitting shroud, water pump, belt tensioner.
Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.
