Answer 1

Its normal..its how our cars warm up.

and as for the exhaust you may have an exhaust leak....you may need a valve job... fuel filter could be bad...you catalyitic converter maybe bad...


have you done the timing belt/water pump and accessory belts?

i have a 98 integra..had a 96 prior :P check out team-integra.net

Answer 2

Cars are designed to have elevated idle rpm until they reach normal operating temperature so, while 2500 rpm sounds a bit high, I wouldn't be worried about that item.

The tachometer needle jumping up and down is a legitimate problem and obviously it's electrical. I would suspect a source (battery/alternator) problem if all the gauges in the car were doing something similar and lights were dim etc. If it's just the one gauge, it seems apparent it is a connection problem. Check all the connections to the distributor and the ignition coil. These two points are typically where the tachometer is connected. A loose connection can cause these exact symptoms.

The exhaust problem is entirely different. Your car's exhaust, with it's associated catalytic converter, produce water. This water is seen as dripping fluid from most everybody's exhaust pipe. It is black from coming in contact with soot and combustion byproducts. All of this is normal. However, anything that produces water must make provisions to drain that water. In an exhaust system, that means everything must be mounted lower than everything before it starting at the exhaust manifold. If your exhaust system comes down like normal but then turns up at any point and becomes higher than any point before it, you will collect water there and water forms it's own plug of sorts. Yes, exhaust gases can get by this sort of plug but it does build up back pressure and, depending on how much of a plug the water is forming, it could turn into little convulsions of spewing ickyness.

Good luck!

Answer 3

First off, relax, your problems aren't too bad.

Let's start with the rpm needle jumping up and down. Long story short, your Tachometer cable is going bad, replace it and the needle will move smoothly again, it may cost about $200.00 to have someone replace your tachometer cable.

Now lets talk about your cars exhaust problem, I don't care what anyone says, your car is running/idling rich, meaning whoever did your tune-up did not do it correctly (was lazy). Besides all the parts mentioned above in your tune-up, it didn't sound like no other adjustments were made during your tune-up. You may have a computer in your car that controls your air and fuel mixture. Something with this needs to be adjusted, or worse, you may need to replace the computer that monitors this, and that's expensive (about $800 just for the "brain chip" or computer). More than likely you just need and adjustment, which you shouldn't be charged since it should of been done with your tune-up.

I hope this helps, good luck =)
