Hi.. I have a 2000 Mitsubishi Galant V6 car. For the past 1 week, whenever the tachometer goes to around 1500 rpm the car shakes/vibrates. When i increase the speed or decrease the shaking stops..Honestly i am not able to tell if its the wheels or the engine. I know i have to take it to a mechanic, my only fear is that if this is a simple problem and i am not aware of it then the mechanic might try to take advantage and jack up the bill. So any help /advice would be greatly appreciated.

It's not your wheels, because at 1500 RPM your not going fast enough to get much vibration from unbalanced wheels. If you had unbalanced wheels, the vibration would get worse and worse the faster you went. In addition to an engine misfire caused by an ignition, fuel injector or emissions related problem, you could have drive train vibration arising in the front drive axles, engine or transmission. So I don't think your shop technician is going to know what the problem is immediately without test driving the car and checking your ignition and emissions tune up items first. Don't be surprised if you pay a little more just for him to troubleshoot the problem. If he can't find the problem right away, you could drive it until the problem got worse. You'll have to "play it by ear" on this one! However, you can sign up your car at the following website to check on manufacturer TSBs, recalls and owner complaints for your car year, make and model:

Take your car to a tire shop and have them check your wheel balance. Ask them if your wheels are statically or dynamically balanced. You can tell yourself by checking where the wheel weights are. If they are glued to the inside of the wheel, it is statically balanced, and if the weights are attached to the wheel lip (where the wheel meets the tire) on both the inside and outside then they are dynamically balanced. Most fancy aftermarket wheels are balanced statically so as not to have an ugly weight on the outside of the wheel or scratch the wheel. This presents a problem since statically balanced wheels have a tendency to vibrate. If you are not concerned with how the outside of the wheel looks, then get them to dynamically balance the wheel. Any competent tire shop should be able to do this for you, and at least that will eliminate the wheels. If the vibration is still there, and if it is an AWD car, your drive shaft from the transfer case to the rear axle may need to be balanced. If it is a FWD car, I would say take it to a competent shop and have them take it for a drive with you in it so you can point out the problem to them.

Use the transmission gear selector to run the engine in different gears. If the shaking is caused by an unbalanced wheel, maintain your speed (mph) when the shaking occurs occurs and shift into a lower gear thereby raising the RPMs and the shaking should continue. If the shaking occurs at around the same RPM in each gear, it is the engine. Remember that mph and rpm are different.

This is tough without being able to see or hear the problem. One suggestion is to go and get the work done if it all sounds like it makes sense to you, and then get back on here and see if the work and bill seems to check out with the other mechanics on here. If you've been had, then tell that mehanic you'll report him to the better business bureau if they don't straighten things out completely. Just a thought, good luck to you.

Sounds like a misfire. Bring your car to an auto parts store and they’ll check your engine codes for free. If it is a misfire, hopefully (and most likely) it can be fixed by replacing your sparkplugs.

sounds like it could be the spark plugs and/or wires
