Popping/Knocking...

Well my Check Engine Light came on Friday when i started the car. Drove it around for a bit and everything was swell. Then on Sunday, I noticed that when I gave it a little bit of gas then let off, I could hear a slight repeadative popping/knocking sound coming from my engine bay area. Then today when driving home on the highway, I noticed it again, but louder. If i kept it at like a steady 2.4k RPM in 4th gear it wouldnt stop knocking/popping, then if i gave it a little gas it would go away, or if I braked it would go away. Then when I got back in town, it wasnt as loud, but still there. It kinda sounded like it was coming from the lower engine/transmission area but i couldnt tell for sure. Also, it does not make the noise while in neutral. Anyone have a clue as in whats my problem?

i ahve the same problem with my car... when i let of the gas or when i downshift i hear that noise. I had a couple mechanics look at it.. one said its the bearings in the transmission, another one said its either my trans or the engine, and another one said he had no clue what the hell it is cus he never heard it in his life. its been making this noise for about 9 months now, it keeps getting louder and louder i think i'll have to fix it soon

nice to know im not the only one with the problem. im going to go to autozone sometime soon to see what the check engine light is for, see if that helps me any...

::wishes he had a datalogger::

This might not have anything to do with you but the bearings on my uncles Dodge Intrepid 1995 200 hp engine have gone bad, and his car has been getting louder and louder as time passes by. I am not sure if this is what you are experiencing though.

hey seth, there is a data link connector under your dash on the driver side next to the center console. if you put the 1st terminal to ground (that is the one in the upper left corner) and count the number of times your check engine light blinks, I will tell you the code!

I tried that a while ago on my car it didnt work. I got a 97, my datalogger works just fine though. =D

well seth doesn't have one so i am trying to help out. i have the service manual so i would be able to help him.

ill try to do that tomorrow, bah i dunno, im bout to push it off a cliff with me in it

don't do it man, it aint worth it, not over this shit.
be cool 8) don't be a fool :spinner:

my wife has the same problem with her galant. sound seems to be coming from the passenger side wheel well on hers. hear it when she pulls off from a stopped position....every time :!:

that sounds more like a lower ball joing, mine only goes when moving...

btw, ive had both my lower ball joints replaced in the last 2 or so months

where did you read that

i dunno, do a search in the 7g forums, mitsubishi did a recall

got it

IMHO it could be the lower ball joint or a strut mount. Let us know if you fixed it and what it was.

hmmm i highly doubt its my lower ball joints, anyone else have any ideas? its really bugging me :evil:

Put the front end on jack stands and start the car up and get under there and you could probably hear exactly where the sound is coming from, maybe even see a loose part flying around..

Funny thing this weekend after puting my engine mounts back in I start the car hear this nasty knocking sound...Im like oops mounts to stiff gona kill the car, open the hood...i was my cell phone that was vibratin around, I closed it under the hood lol good thing I didnt drive off!

well the thing is, is it only does it when moving. wont do it in park or even in neutral while moving. only when in drive when i give it a lil and back off...

you have any ideas Manny?

Forgot to mention that you will have the car in DRIVE and the wheels will be spinning away....the engine WILL BE MOVING =D If theres no noise when you rev it or hold the gas as it changes gears, then its probably got nothing to do with the engine and something in the suspension or whatever other crap is screwd.

yah then the car falls of the jackstands and im dead :lauging:

i think im just going to take it into a shop :roll:

I've got a little popping and knocking going on with my 96 TOO.

I just had her in the shop today to replace the ball joints (factory recall). They told me that I needed to replace my inner tie rods. They showed me where they moved back and forth.

They quoted the whole deal at $400. I just looked online at www.oreillyauto.com and the parts are $37.00. I'm going to pick those up today, replace them tomorrow and get an alignment immediately afterwards for $40. It just doesn't make sense to me that they could charge me $400 when I could do it for $77. I guess that means that I can put the $333 I saves towards my turbo project. WHOO HOO!

Maybe your inner tie rod ends are causing the "popping" like mine are. Its not hard to diagnose.

tie rods eh? anyone else have any say? how hard is it to replace tie rods?

Ok, nother update. Drove the car around today and it was really loud! Kinda sounded like it was coming from the driverside wheel well. So I stopped at walmart and got a bar out and went to see if that metal gaurd was hitting the rotor. Bent the guard so it was definitely not hitting the rotor, drove home and it still was there.

The faster i went, the louder and faster the popping/knocking was, slower i went quieter and slower the popping/knocking ocurred. Also, if i turned the wheel to the left, the noise seemed to be quieter. Also, when i brake, the noise still disappears as well as when i accelerate to a certain extent.

Im going to go buy some cheap brake pads tomorrow and see if it helps at all.

Hmm maybe its the wheel bearing on that side. Louder as you drive faster, and quiter when turning in a direction are some sympotoms of wheel bearing problems.

sounds to me like it could be your CV Joints going bad.

hmmmmm are there anyways to be sure about any of these? im going to work on the car tomorrow so...

wow, this topic has been all over the road. Yo seth, all of the things people have mentioned can very well be the cause of a popping and knocking noise, but they will not cause the check engine light to illuminate. Whenever diagnosing a vehicle's problems, you have to start with the obvious leads. In your case it's a d.t.c. (diagnostic trouble code), that caused the check engine light. Find out why the light came on and take it from there.

alright, im goin to autozone sometime soon then. dont know where the closest one is to here but i know theres one in my home town. i can get it done sat there but prom is sat night, and i wanted to get it fixed before then hah if thats possible. so i guess ill keep u guys updated...
