    I went to transmission shop. the mechanic drove it, said transmission is fine. I went to auto zone and had the code read says P0420. I replaced both cats in the past month. I have changed the spark plugs and wires... I dont know whatelse to do,,I am unemplued and limited funds. The code also says vacuum leak?? Someone suggested a smoke test to check, but I cant find a shop here in Orlando that does that...

    All I can say that EVERY repair shop has to have an Evap Smoke Machine to use in many different ways or they may as well go out of business

Well you have to always use the scan tool & road test
to look at data

Transmission aside you have to see if the motor runs properly

Bucking could be old spark plugs,failed ignition coils,bad egr valve
& more,basic preventative maintenance your not aware need to be
done every 2 or 3 years & look at data a couple times a year

Since 2005 the exhaust converter may be worn out so look at the
scan tool info on a road test no dealer is going to do much that is needed

If you failed to change the trans fluid every 3 years then who knows
how that's doing,not well possibly.

The dealer wasted your time,blew you off

Lift the back of your car.With a stable rest and with the two hind wheels hanging, run your car up to the speed where you experienced vibration. have someone take care of the throttle and shifting while you observe the transmission shaft. You may have an imbalanced shaft.

If the light flashes on and off, the vehicle has a severe problem that will cause additional damage. You should not be driving the vehicle.

Get a third opinion. I don't see how the Suzuki dealer person could diagnose a problem from a phone call.

Take off a wheel and see how much brake pad you have left. The pulsating sounds like the rotors need resurfacing. Replacing pads and resurfacting rotors shouldn't be a major expenditure.

Front wheels shake going down the road

If you have not hit anything 95 percent of the time it is a tire issue. Can even be a tire issue if you hit something. Broke a belt in the tire. One of the weights came off the rim. I had a garage swear it was a tire rod end once and it did not fix it. Turned out they did not even check the tires. Turned out to be a busted belt and a missing weight. Could have saved myself 800 bucks in labor

There is a very loud humming noise coming from the front left tire! plz I await your reply. Thks.

You probably have a bad tire or wheel bearing. Either the tire is cupped causing humming noise or grease inside sealed wheel bearing is burnt up. I would take front tire and move to the back of the car. Then drive again. If noise stays the same you probably have a bad wheel bearing. If noise moves to the back of the car than you may need to replace the tire. Most likely it is the wheel bearing, I replace them all the time at my shop

I have had my 2002 Deville at several service garages and no one can solve the shaking/vibration problem the car has. The car starts shaking at 50 + mile per hour and above. I have 20 inch devanti rims...

don't listen to the guy who says buy new tires!! I took my 20's off bought new pirelli's and 18's replaced tie rods,wheel bearings and then finally ran into a real mechanic and he replaced both cv axles and it rides like a caddy again.He said the shaking is usualy caused by the inner joints which are the ones farther from the tire.Grab it and try to move it ,it shouldn't move period!!Also check for grease around it as it will throw grease once it's real bad.Advanced has them for 60 a piece and i got charged 2 hours of labor at 90 bucks an hour
trust me change em'!!Don't listen to anyone that says different,I did and it cost me!!

At 40 mph the car starts to shake. It last to 5o

I have this same car with exactly the same problem. Begins shaking at 40mph and stops shaking as soon as you let off the gas, but then begins again as soon as you press on the gas and smooths out as you get over 50. And the shaking is not felt through the steering wheel. Solution: Replace the transmission mounts. There are two of them, one on each side mounted on the frame right next to the shock strut. There is also a front and rear engine mount, but I replaced the two as described and shaking is gone.

2001 madza shakes

This usually is just either a wheel got scraped into a curb or hit a pot hole so the wheel is off balance or one of the weights came off and still it would make it off balance but its a easy and cheap fix you can either rotate your own tires and put the fronts to the back and backs up to the front or take it to a tire place and have them balance each wheel it costs about 10 bucks per wheel to be done, if you have any other questions just let me know id be glad to hel[ also if you get a chance if you could rate me it would be greatly appreciated..
