Shudder from front when gas pedal slightly depressed [appears to be solved]

[jackdog1]

I have a 97 Honda Civic EX Coupe with automatic transmission, and I just started having a minor shuddering issue. It's only happened twice, but when I have the gas pedal barely depressed the front of the car shudders significantly until I either let off the pedal or depress is more.

I don't hear any change in engine tempo, and the plugs, ignition rotor, and dizzy cap are all new and the resistance on the wires is perfect. No CEL light or codes (and I know it works 'cause I accidentally tripped it a couple weeks ago!). Last I checked the engine mounts are intact, though look like they've seen better days.

Most of the time it's the CV axles. Would not be a bad idea to get those checked as well as alignment.

Alignment's perfect, but if it keeps happening I'll get the CV axles checked then. What exactly would be wrong with them that would cause the shudder? And why only when the gas is barely depressed?

Just had this problem with the CRV, replaced the right front axle and problem was fixed.

This probably sounds like a noob question, but assuming one/both of my axles is the problem, how bad is it to hold off on replacing those (e.g. just an annoyance or indicator that my axle is about to break)?

I really don't want to spend another hundred or so right now to replace an axle, but I will if I have to.

it's not recommended due to the amount of vibration that a CV can create you can actually cause damage to the wheel & differential carrier bearings over time.

stuttering is usually cause by bad brake components or a wheel alignment issue also your ABS could be locking up due to bald tread on your tires when you go to accelerate

i own a 97 EX Sedan

if its based on when you go to accelerate soley i would check to see if your ABS light is on then thats going to be your source right there unless of course its coming from the rear and thats somthing else i believe you can deactivate you ABS via fuse under your hood

Totally irrelevant, as mine doesn't have ABS.

 

[Bradley Robert]

kinda odd seeing how i own the exact same car but it does good luck with your problem man

next time before your so quick to type "irrelevant" on somthing due the homework first canadian SI and SIR trim package for those years both came with ABS so did the EX it wasant released in the US

And before you are so quick to type "owned," maybe you should do YOUR homework first. Not all EXs (mine included) have ABS brake systems.

My car doesn't have the ABS sensors, ABS instrument panel light, or a fuse in the ABS slot.

And really, if you're going to correct someone, use correct spelling when you do.

It isn't relevant anyway seeing as it happens when he gets on the gas and not the brakes. Even if he did have ABS I doubt slight acceleration is spinning his tires.

That's what has me so confused: the couple times it happened, my car wasn't going that fast.

LMAO........................trolls always go back to bash spelling


every EX in canada did for 97 it also came with SOHC VTEC not much but its good for the sedan sorry you
ended up with the barebones base model champ

judging by your comment "ill get my cv's checked" you have no idea what your doing and your fishing for cheap solutions you can do yourself and on the side you check peoples spelling
you should probaly pick up a haynes manual and do somthing more constructive with your time


my car dosent have ABS i have the american model would have been the correct answer


"i checked my ignition coil to see if that was the cause of the shuttering".......................really??? and your here writing stuff like that and telling people whats relevant and what isint way to go pal!

Well of course I have the American model, I live in America and the car was purchased in America after all. I updated my location to say "Pennsylvania, US" since you were obviously confused and thought there was a "Pennsylvania, Canada."

If you're going to quote someone, at least get the wording right. Shuddering can be caused by the engine misfiring, that's why I mentioned that my ignition system was fine to rule that out as the cause (and I never specifically mentioned the coil).

What I meant by the comment "I'll get my CV Axles checked" is that, after giving them a once-over myself for any obvious faults and if the problem persists, I'll have my dealership look at them. I don't have the time, tools, or experience working with that specific part of the car to accurately diagnose it myself.

As for picking up a Haynes manual and doing something constructive, are you referring to the kind of manual that I keep in my trunk? It's was very instructive when I was replacing my radiator, distributor cap, ignition rotor, spark plugs, front brake pads and rotors, valve cover gasket, and fuel filter.

And for the record, I've had issues with off-balance brake drums/rotors before, and know what those sound and feel like (specifically, a faulty aftermarket brake drum). This is completely different, and likely involves no part of the braking systems of my car.

Also for the record, I wasn't the only one who said your input was irrelevant.

Now, to get this thread back on track.

I got the chance to visually inspect the CV axle and knuckle assembly on the driver's side earlier today. Nothing's obviously wrong there: both boots were intact and pristine, all the castle bolts were on snugly, and the axle bolts were tight. I could only turn the axle back and forth a little bit with the car in gear, but it moved very smoothly and silently. I still have to examine the passenger side one (I got distracted when I noticed the glitch with my taillight). I should also mention that it didn't shudder at all when I pulled it into my driveway (I park on the street).

The guys at Advance Auto mentioned that if it is the CV axles then I should notice a clicking noise when driving. Since it only shuddered twice within minutes of me getting home, I'll take it out on the road again tomorrow and see if I hear any funny noises coming from the axles or anything else.

ABS is not just on the front, anti-lock braking system, is on all 4 corners. The ABS is activated by wheel speed sensors installed in the knuckles and utilizes a hall-effect type sensor in conjunction with the inside of the brake rotor.

Bald tires wont necessarily cause this problem, wheel spin (traction control) and very low tire pressure can cause your ABS to activate.

youve already bullshitted enough and gave enough examples in your boring rambles that you have no concept of what your doing stop trying to use long drawn out paragraphs to try and sound smart its lame and boring already i didint bother to read half of what you wrote back to autozone young man to continue asking questions

 

[Bradley Robert]

im in full support of people coming here to ask a variety of questions thats understandable but people that come on these sites to try and act smarter and more in depth then the people there asking are total clowns
