I just bought this used car a few months back and I know its used and I probably should have went for a different car.

My car when idle and stopped makes a weird rattling noise that is pretty loud and embarassing. I know nothing about cars so I guess I wanted some advice from here so that when I went to the repair shop I wont get jipped, especially with me being a girl.

As well if I accelerate slowly sometimes the revs just keep going up and wont go back down.

Other than these two things the car runs fine, in my opinion.

Oh and my check engine light goes off but Its because of the gas cap and something about air. Im not sure can anybody tell me about that. Do I need a new gas cap.

If you know what could be wrong pleassseeee let me know, hopefully its not something that will cost the price of another car. :( :( :( :(

The rattling noise. Take some time and check out the heat shields on the exhaust system. They should start from the engine on back and that is a problem with them as they get older. Careful as they get hot but check that out.

Replacing the cap is an easy thing but what is the code your car is giving off?

Im not sure what the code was, but when I bought the car the guy showed me the paper and he said that it was nothing and that it had to do with the gas cap and the air was going in or something like that.

I know im stupid for not making sure when I bought the car, I made a bigggg mistake buying it.

The heat shields, okay I personally dont know what that is but I will ask a friend.

The sound seems like it just comes from the front of the car, and what about the reving.

Thanks so much!

How high do the revs go up? 3000 rpms? More? Is it standard or automatic? My girlfriend has a 2000 jetta auto, which I realize is the newer style, but sometimes when she accelerates slower, the transmission is less likely to shift to the next gear, so the revs in town sometimes go up to 3000 or so. I have also wondered about this, but have been told to have the transmission serviced, which is usually $100 or more, or sometimes I guess you can put some sort of conditioner (not hair conditioner) into the transmission fluid to kind of lubricate it. Not sure, but you can always go to a shop and tell them what is going on and even have them check it, but just tell them not to do anything. The worst they could charge you is $30-40 to check it out, but just ask them. Lots of time if you tell them you want to know how much it is to fix it, they can kinda give you an estimate and tell you what is wrong, and then just don't go back :P I'm a college student so I hear you with the money situation.

Yeah. That's exactly what happens, it seems like if I accelerate too slowly it will go all the up to 3, im not sure if it goes higher because by that time I notice it and i'll let go.

It really causes a danger to me at times, because in the middle of the road i'll be going super slow.

Thanks a lot! I will mention that to a mechanic! At least I know what was wrong with it now and I will seem like I know what i'm going about!

Thanks so much

Ya, well sometime what she does it say it is kind of hovering around 3000 and won't shift up, just kind of give it some extra gas, don't floor it, but kinda, like you wanna accelerate. That typically makes the car shift for her. Also, this happens more when the engine is cold. If you do give it some extra gas and it goes up past 3500 or 4000 rpms, don't give it any more, as that is too high of rpms. But ya, just thought I would tell you my experience.

Take the car in for a flush and fluid replacement on the automatic transmission. Make sure that they only used Honda certified tranny fluid.

Heat shields are the pretty aluminum metal covers that wrap or cover the exhaust pipe. They start up at the engine and there is usually a cover over the exhaust manifold as well. They usually go all the way to the rear of the car. They help reduce the heat to the floor of the car and other items as well. They get hit, old, corroded, etc and will vibrate or rattle.

It might just be a good idea, get it fixed so its working decently, and then sell it. Buy something with lower miles and newer, even if it is a somewhat "uncool" car. Like a hyundai or kia, and they have a 10 year, 100,000 mile warranty. How many miles on your car?

Yeah, you know, I have already posted my car on craigslist. And i've been looking for a honda civic. My car has 112,000miles, it's not too bad, but I think I will sell it, just so I can avoid any more problems later on!

I just wanted to update, that I went in the change my oil and the guy told me that he thinks it's the pistons and lifts that are shaking. I told him about the transmission but he couldn't check it because I need a mechanic to open up the transmission.
