I bought a 1999 Accord Ex sedan (Honda certified) about five months ago.... it has since developed a (somewhat quiet) rattle in the engine on acceleration... nothing big. What could this be? My old (1988) accord did this too, but it was old. Do you think it could be something covered by the pre-owned certified warranty?

Thanks

rattle, prolly a loose heat sheild somewhere on the exhaust

 

couldnt that be just that it needs a valve adjustment?

 

yah check the valves!

 

i know i need to adjust mine, they're ticking worse than a turrets patient on crack!

 

I thought a constant ticking persues a valve problem.... (tick tick tick tick, etc.) this is more just a rattle that only lasts a few seconds during accelaration... Someone told me to try using a better gas station's gas...

Any thoughts?

thanks

what all mods have you done to it?
have you done exhaust?

 

yeah i hear it in my engine to when i accelerate, i was going to post it on here sometime. it usually doesnt happen when i press more on the accelerator. but its pretty bad in the morning when i just start driving my car. It more of a clicking noise for me though

 

all accords and maybe civics have this. its the rough idle caused by a poor distributor. someone told me it is a friction gear, but this was from a probe guy, so i would need a second opinion. as far as after the car is warm and upon acceleration, definetly something in the exhaust, either a heat sheild, or loose bolt holding up the cat, or mufflter or something.

 

Gotta describe the noise and circumstances a bit better? Could be pinging? Detonation? Or does it surely sound like a metal part shaking?

 

Im getting a cat-back system this week or next week so if its still going on with my new exhaust ill let yall know

 

+1 Had the same problem on both accords. Easy fix with a metal hose clamp (but much larger).

 

thanks for those tips. now it gives me an idea where to start looking. been scratching my head since winter started.
