1990 crx si,
when i shift and slow down there i a poping sound, a loud one
it sounds expensive nd im hoping to get some imput as to waht it is

 

It sounds to me like you are running really rich and that popping noise you are hearing is excess fuel being detonated in the exhaust system. However, lets get a second opinion.

 

it doesnt sound like a backfire, it sounds like metal hitting metal

 

Sound Clip would help

 

i have no idea how to do that

 

where's the noise coming from? or do you even know? and this happens when decelerating correct?

 

its comming from the engie compartment, ad i can feel it as well and yes it it happens while decerating and while shifting

 

Sounds like a loose mount or some thing

Check all your mounts and suspension belts

 

thats whats im hoping

 

can you duplicate the noise with the car parked?

 

no, only when i let the clutch out and give it gas so it jumps

 

you know what you could do....set the parking brake, chock the wheels and load up the engine. do it right now....gogogoog, and you need a helper also, dont stand in front of the car. what the engine movement and listen for noise. inspect engine mounts

 

sounds like a mount is shot or maybe you have a bad bushing in the suspension

 

i checked out the mount and i knly found one that looks kinda shot but not enough to make a sound like that but i could see it bring a bushing, ill have to check that out when its light out and not raining

 

sit inside the car than and load the engine. spike the gas pedal. if the noise persists than its most likely a motor mount. are you sure its not a clunk? and not a pop?

 

honestly it could be a clunk or a pop, but i cant get it to happen while im not moving, only when im in motion

 

well the point of this test is to get your engine to jerk in which ever direction to see how much engine movement there is. all that excessive engine movement leads to bad mount(s) causing clunks...

 

while doing the test have somebody see if the motor is moving more than it should. is it coming from one side of the car or just under the hood

 

i hope its not your loose tranny mounts. I had a rear tranny mount get loose and crack the tranny housing and it did just that. It popped till it broke and i think i could have saved myself a headache if i just made sure to torque my bolts properly.

if it is just as the clutch comes out then it could be the rear mount...

 

serious bearing failure in the transmission will also cause clunking. if the input shaft bearing fails, you get all kinds of strange noises.

check your mounts first. if none of them are bad.. then it *may* be trans rebuild time.

 

axles?

 

axels are good, and i am starting to think it may be something internal but i hope not
