Question about 1989 Oldsmobile Cutlass Ciera

Knocking While Accelerating

When I accelerate I hear a knocking sound coming from the drivers side of the car. I cannot tell whether it is directly under me or if it's in the engine. It only happens while moving and while I am accelerating. What could the problem possibly be and is it possible to fix it without seeing a mechanic?

    I just put it in drive, stepped on brake and gas and it still knocked. When in neutral I did not hear any knocking. This started 4 days ago and has gotten worse. If it is the timing, would it get worse or could that be another problem?

    It is a 1989 Oldsmobile Cutless Cierra. It has 133k miles on it. I drive back and forth from classes everyday, and they are about 15 miles away. I don't take it above 70 mph, and I only go that high when I have to take the highway. I do not run it hard because it is an older car. I do not hear a ping with the knocking. There is a click from inside the engine when its idling, which from what I understand could just mean that I need to have my valves checked. But that started today.

    Thanks ****, I greatly appreciate your help. It helps a lot. Otherwise, I'd still be clueless. Thank you again.

    Hi guardian.326 how old is the car,how many miles on it etc. If it was a bearing knock (main bearings) it would be there all the time, It could be a few different things but for now I think that timing will be the issue from what you have described. one more question: when you accelerate along with this knock do you hear a pinging sound?

    Guardian.326, all that is needed to check your timing is a timing light, I would not think a mechanic would charge you just to check it out, if it is timing it will be slightly retarded and need to be advanced, to adjust this takes 2 minutes good luck and let me know how you make out and we'll go from there

    Guardian.326 the first thing you need to do is get the timing checked, the clicking you hear is probably lifter noise. Make sure the oil is good and get the timing checked ok, thats the cheapest place to start then let me know whats happening ok, I think that will fix your problem, good luck to you.

First check wheel bearing. Jack front end up lifting tires off ground and see if the wheel moves by pulling on the sidewall part of wheel from top and pushing bottom towards the car does this back and forth if there is play, wheel bearing could need replaced. Take tire off and check for loose brakes, loose calipers, loose dust shields , etc. everything except rotor should be tight.

Knocking sound when accelerating


Where is the knocking coming from? The engine or the transmission? Can you feel the knocking, or just hear it? If you can feel it, is it in the steering wheel or do you feel it in the seat, or the whole car? Is your check engine light on? Let me know, I will try to help. Went through the same problem recently, and even though I have worked on my own cars all my life, it takes a little detective work to find out what is wrong on your own with these newer cars. It could be anything from an unbalanced tire, to valve problems, but there are ways to check and eliminate things. Give me all the info you can, and I will give you the best advice I can. e-mail: jakel1_1@netzero.net.

When applying breaks and then releasing and accelerating there is a knocking sound coming from under the car


Could possibly be a transmission/engine mount? Without hearing/feeling it myself its hard to tell you with any certainty what the sound is, but the mounts are a common cause, also seen severely worn ball joints do that too, but they will usually make a lot of noise with bumps and at that point your steering would feel a bit odd too..

Why is there a knocking sound when turning?


to test make your turn nice and slow with no throttle, then make the same turn accelerating slightly, if you hear the knocking/popping noise louder when accelerating, then it is probably the CV axels. get a free inspection at mieneke:).

'99 Forester with a knocking noise at idle and acceleration


sounds like you have a headgasket blown, a head, or your rocker arms or lifters whatever you prefer to call them are running dry. might be time for oil change and coolant flush. If ther is no overheating or coolant smell than get your injectors checked. You might just have a broken seal that emits louder sound from the pulsating injectors. Good Luck!

Knocking sound


maybe cv joints. check cv boots to see if torn or look out for grease marks in the area behind front wheel. This would be more clicking noise though and not banging.
