Question about 1996 Mitsubishi Eclipse

2 Answers

I just had my muffler/exhaust system changed at a garage. Before I brought the car in it was loud, but otherwise ran fine. Since I picked my car up I have noticed that now it struggles to reach cruising speed, sputters and feels like it is going to die. Sometimes it puffs out black smoke out of the pipe and now I am burning gas like crazy! when I step on the gas pedal the car struggles to go, before it was a nice smooth sound coming form my muffler, but now it sounds like some heavy muscle car, with its rumbling spitting coughing sound

Sounds like they choked up your exhaust to much. What you needed was a quieter muffler. Buy having an exhuast that is to small on your car it will kill gas mileage and power. Most mitsbishis like a 2 1/2" exhaust, and if your have a turbo motor anything under 2 1/2" will really kill perfomance.

First of all , i would say check your oil pressure.second i would take a look at your oil pan and the screw that holds it together.because some times they put them on too tight scripping them,that can make it do most of the things you described above.or if its not tight enough,it could do the same. i hope i was helpful in some way. good luck

2001 Dodge Caravan SE Suddenly got VERY loud

I have no practical experiance on this american vehicle but if the O2 codes are coming up then its possible that one of the sensors has come loose and fallen out ,but if you had it looked at by a garage somewhere and they said to replace the whole exhaust then something is amiss here and without a my head under the car i couldnt tell you from afar ,either the garage is after a easy job with a good profit margin or its fallen apart so i would advise that you ask another mechanic to have a look for you

Loud noise coming from the exhaust

You should try inspecting the exhaust from the underside of the vehicle.
Typically if the exhaust has become very loud, then there is a likelihood that either one of the pipes has corroded through or cracked, or that one of the muffler boxes has failed. To check the muffler box in the case that there is no apparent exterior fault such as corrosion or cracks, then with a cool exhaust or protected hands, shake the exhaust or hit it with your palm under the muffler box. If you can hear a clunking, or lots of loose rust inside the box, then it has likely failed from the inside first.
Exhaust systems generally corrode from the inside out as water is a product of combustion and tends to condense inside the exhaust system.
If you are wondering how long an exhaust system should last, then this is a tough thing to measure. However as water presence is one of the main reasons for exhaust failure, it is common that vehicles which travel extended distances where the engine and exhaust systems can heat up to full operational temperature tend to suffer less corrosion in the exhaust system. This is because the matter of condensation of exhaust gasses is largely prohibited by higher exhaust temperature.

One last thing for you to check is the condition and fit of the exhaust headers or manifold. If you have suffered a gasket failure, or crack in this area, then you will pick up on a higher volume of exhaust noise output.

Good luck.

I have a 1997 chev cavalier, and as I was driving I heard a dragging noise, I looked under my car and the tube from the exhaust that connects to the muffler is off, what will i need to fix this, my brother...

Take your car to a muffler shop and ask them if it's possible to reweld the exhaust pipe to the muffler. If the exhaust has rusted too thin, they wont be able to weld it safely, at that point you will have to replace the entire system unfortunately. Exhaust systems comes in sections, so ask them if its possible for them to replace the exhaust from the catalytic converter back only. It should be cheaper if they can do that. Good luck!

Starts but dies right away

I had the same problem. My cat. converter went which plugged my muffler and choked out the car seconds after starting it. I took the exhaust system apart between the manifold and and cat. (3 bolts behind the motor by the firewall) then started the car and ran fine. I now need a new cat. and muffler for my 2.2 Alero.

Loud noise (like a motorcycle) coming from 1994 Nissan Murano

check your exhaust system and your muffler. a noisy fuel pump doesn't make sense, especially because a new one didn't change anything. if your muffler even has a tiny hole in it, it would make immense amounts of noise. the fastest way to check it (and you have to be very careful here) is to cover the exhaust pipe entirely with your hand RIGHT after starting the car (so it's still cold) if your hand is pushed off by a lot of force building up, then your exhaust is fine, if your hand can stay there with no resistance, and the noise gets louder, there is a leak in the exhaust system

Loud Vibration from Car When Idle

You need to take the car back to the place that did the exhaust work. What you are hearing is the exhaust system (pipe, muffler, etc.) touching the underside of the car. The exhaust system is mounted along the underside of the car with exhaust hangers (usually made of rubber) also called insulators. The reason you don't hear it when going is because when you step on the gas the engine torques causing the exhaust system to move away from what it is touching.

Lack of power

If the catalytic converter disintegrated before you replaced it, the muffler may have been clogged by chunks of ceramic falling from the cat and migrating back to the muffler.
Try this: drive the car warm, then stop and with a helper to gradually raise the RPMs while standing, listen at the tailpipe. If you clearly hear the individual firing of the engine then the system is probably clear. If you notice that the sound is more of a hiss, then either the muffler or (if it has one) the resonator are clogged.
On a car with a heavy-gauge stainless exhaust system, two shots from a .357 magnum into the tailpipe opened it up again (forever) and didn't really make much difference in the loudness of the exhaust. I wouldn't recommend doing that with most exhaust systems though.
