2006 vw jetta will not accelerate and tail pipes shakes and puffs

SOURCE: Tail Pipe Replacement on a 72 VW Beetle

Heat the area by the muffler with a torch. Try not to heat the tail pipes themselves. Then take a pair of channel locks and wiggle them out.

It often means that you are burning antifreeze. You asked if it needs antifreeze, have you noticed any leaking out of the reservoir tank while you are running it? Sometimes when the head gasket goes it will produce a passage for the antifreeze to pass from the capillaries into the combustion chamber. It is easy to check if you have an air compressor. Remove one of the rear sparkplugs and the radiator cap. Fill the radiator and then push some air into the sparkplug hole (get a good seal in case a valve is open). Repeat with all the cylinders and watch for air bubbles coming up into the radiator. If bubbles come up or fluid is pumped out, the head gasket is blown and must be replaced. It is more likely to happen at the back of the engine because it is farthest away from the fan and therefore gets less cooling. Also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings.

You need a code scanner hooked up to it to find out why that light is on. If you have an autozone near you,go there they will hook one up for you. Takes about 30 to 40 seconds. If not call around.

I had to take my car back to the dealership twice. First, they replaced the ignition switch. 3 days later, my car wouldn't start again. So I took it back and they called VW - VW said to replace the steering column module. I asked my dealer why they didn't replace the steering colum module first - they said that even if they had replaced that first, the old ignition switch would have shorted out the steering column module. Whatever.
$600 later my car has been fine for about 3 weeks now. If it happens again I will keep you posted.
Good luck!

I had the same problem with my Passat 2000 , I started to put "Smoke no more" the next day after every oil change and worked pretty good. Every bottle coste me about $4 at Pepboys...
