Any idea of how much this will cost?

[jmcoreymv]

Ive got an old 90 4dr LX Accord with 100k miles and a manual trans. Lately when Ive been idleing at stop lights and what not, after the engine warms up a bit, the rpm will sink down to 2-400 rpm rather than the normal idle range of approx 800 rpm. The car starts to shake pretty bad and I find myself having to keep my foot on the gas to keep it around 1100 rpm. My dad thinks its missing a cylinder but doesnt know how much itll cost to fix. I dont really have too much knowledge about cars. Any ideas?

If a cylinder was misfiring, it would be VERY noticeable (noise, lack of power) when you stepped on the gas. It sounds like your idle needs adjusting, thats all.

How would I adjust the idle?

It just needs a tuneup, dude. lol.. Make sure all your vacuum hoses are plugged in, and all the valves and stuff that go along with the vacuum system are functioning.

Take it to the mechanic.

sounds like you just need a tuneup. If you didnt take the car in the the 90K servicing I would absolutely recommend that as well to replace the timing belt. If that goes on a honda then...say "buh-bye" to your car.

Try posting your question here, might be helpful as it's specif to Accord owners.

jmcoreymv, you could also pick up a Chilton or Haynes book for your Accord, they are quite useful to have w/ you in the car.

It could very well be a vacuum leak. That would definitely do that, but they are a real bitch to find sometimes

Just try taking it in for a tune up. If that doesn't fix it, then try taking it into a specialist. I doubt it's that expensive. But if something major is broken, then yes, I can get very pricey. Just shop around, don't just stick with the first person you visit.

I have a 91 accord ex and it does that from time to time.... would be nice to find out what does it... i have a few theories... O2 sensor or vaccuum hoses..
