Question about 2008 Volvo C30

Open Question

I have a Volvo C30 Stick Shift - fun to drive but has most annoying problem - at low speed in traffic or even when reversing, if I depress the clutch, the car quickly revs to about 3000rpm before dropping back down to normal idle speed - it has been in to the local Volvo dealers umpteen times to fix, but they cannot find the problem - any suggestions?

SOURCE: 76 volvo 240 car idles and low speed is rough,

It could be the filter. Has the fuel been changed after storage? I would also thing the Carburetor or the fuel injectors might need to be cleaned.

These models had a problem with the electronic control modules, and this is what controls the idle speed. Sometimes they just need to be cleaned, but sometimes they are defective. Volvo has extended the warranty on some of them to 10 years or 200,000 miles if it is found to be defective.

It sounds like your fuel pump is having a problem with getting the last of the fuel from your tank. The pump also has a strainer on it. The unfortunate reality with the 1993 Volvo 850 is that the pump and strainer are located inside of your gas tank. You can look for kinks or pinched areas in the line but from your description it sounds like the pump is going. It has to work much harder when the fuel is low in the tank.

SOURCE: Volvo S60 sensor ?

Sounds like an oxygen sensor (there are two). I had a recent problem where I had a rough idle and my S60 continued to stall out. Turned out to be the rear oxygen sensor. After replacement, car idles nicely and car drives normally.

Do you drive with o/d on or off for normal driving when do you use it

You can drive with the switch on or off, it doesn't matter. Most vehicles default to the "on" position every time the engine is started, I'm not sure if yours does. The reason you can select the O/D off is because in some driving conditions the transmission will shift in and out of overdrive several times and it gets a little annoying. These conditions could be while driving up a grade at freeway speeds or driving at close to normal speeds but in heavy traffic. Every time the transmission shifts, it generates a little heat. Normally that heat is dissapated through the cooling system, but if the transmission keeps shifting in and out of overdrive, expecially in heavy traffic or climbing a grade, the cooling system may have a hard time keeping up. If you feel the transmission shifting in and out of overdrive more than usual, and you're in an abnormal traffic condition, go ahead and turn the O/D off. Just remember to turn it back on again when traffic returns to normal so you can get the best fuel mileage.

How to check trans fluid 96 volvo 960

Look way down just behind the throttle body intake assembly, low on the drivers side near the firewall and below the brake fluid container. You'll see a square yellow dipstick which doesn't have a handle on it. It which accepts a 3/8 inch drive extension: stick the socket extension on it, reach down and depress the hold-down clip, and pull it out. It is sometimes easier to reach from the side of the car, reaching down low. Or just reach down and pull it out. You'll need a long funnel to put fluid in. Be sure that the car has been driven 15 minutes or so, stop, move to and stop in each gear about 5 seconds, and back to park. Check fluid level. Don't overfill by even a small amount.
