Clicking sound


There are obviously many different potential sources for this noise!

It would be helpful if we could know exactly where you hear it coming from, but, alas, I will give sometips.

If it happens during acceleration, then it could be from "pinging" from bad gasoline, you could change to a higher grade (87 to 91).

A rotating part such as a pulley, water pump, etc could be making these noises from under the hood. If you hear it, try to open the hood and listen to isolate the sound!

It could be coming from the transmission. Your torque converter may be slightly tapping the housing (not likely, but have seen on another vehicle that had a tranny job done recently).

Again, if you can further narrow down the location, it would be helpful.

Are any check engine lights or ABS lights on, or any other abnormal lights on in the dash?

Is it an automatic or manual trans ?
An automatic should downshift when you push on the gas pedal. The shaking could be a miss-fire or lack of fuel. The noise could be a knock from the engine or something in the exhaust system.
The freaking jet noise could be an exhaust leak or something going on with the air cleaner or a vac leak.

Help, I currently have a 2003 Mazda6 manual hatchback, it has done approximately 195,000km at this point in time. I recently had to get my clutch replaced at 190,000km since it was warn out, note i...


will try to assist you. did you have your clutch replaced professionally? if it's a popping or cracking sound when accelerating or turning, it's most likely a c.v. axle going bad. either on driver or passenger side in the front of the car right?if it is a bad c.v. axle it will pop and crack when you turn wheel from left to right at low r.p.m. if not this,you may have brake issues. either it's a grinding sound while accelerating or decellerating,as long as cars in motion the noise will persist.try tapping your brakes while in a parking lot in slow gear,hear something from driver front,have a passenger with the widow down on passenger side, hear it from front passenger side? the thing i go by is what i hear when i test drive to diagnose an issue with a vehicle is,axles?popping and cracking when turning the steering wheel from left to right at low speed. [axle problem] grinding,scraping sound? brake issues! hope this helps and thank you for choosing fixya.com and we are here for you 24/7 7days per week thank you!!!!

When coasting or slow acceleration I hear a tapping noise from the engine compartment. Goes away when I accelerate.


Check your oil immediately. Tapping is indicative of either low oil level or poor oil circulation. Running the truck under either condition is hazardous to your engine.

Engine taps when accelerating, let off gas and it


HOPE IT'S NOT PISTON SLAP, IF LACK OF MAINTANENCE WAS THE CASE MAY BE INTERNAL DAMAGE OR VALVETRAIN DAMAGE. IF IT RUNS ROUGH MAYBE SOMETHING ON ROTATING ASSY DAMAGED.

Accleration problems 1998 ford f150 v6


probably the belt making noise , very common .

WHen a belt gets old it gets dry and cracks start to appear , the non-ribbed side of the belt may get dry & glazed also make noise . common problema are also tensioners that make the belt get out of line with the rest of the pulleys , look carefully because just a little miss-alignment can cause a belt to slip on the smooth side of pulleys and make noise . Misting water onto the belt may also help you determine what is making noise.

Good Luck and Watch your Fingers !!!!

Mysterious car noise


Check the oil first, if it is low it will cause a host of noises in the engine.

It sounds like that may be the problem you have

Rear acceleration noise


Try rear wheel bearings. The cause a roaring noise that increases with acceleration. Sounds very similar to loud road noise.
