White smoke - muffler - car hiccups
Hi,
I own 1997 VW Jetta GLS , manual transmission with 137,000 miles on it in Michigan. I am pretty much a novice at car maintenance. Off late I have noticed 2 problems: any help is appreciated. 1) Whenever I accelerate my car from rest, I hear a big growl/rattle coming from the rear of my car. Also, I feel as if something is moving, the kind of feeling you get when a small bag moves about in your trunk when u accelerate. I looked under the car and nothing seems to be jutting out or no pipes hanging loose. The problem seems to be further highlighted when the road is sloping upwards. 2) Its been quite cold and rainy off late and my car is parked outside. So thats bad news right there! This morning I noticed my car puffing away thick cloud of white smoke (my muffler and exhaust pipes were replaced 2 months back). Also I noticed that my car engine isn't sufficiently heated so I waited, but nothing changed. What makes it worse is that when I shift from 1st to 2nd, the car jerks/hiccups and it seems that its going to stall and stop. Infact it did so on an up-ramp of my office parking lot. Its an uneasy feel behind the wheel because the car seems to panting. please help, dg. |

May be time for a new fuel pump and filter. I would also take a good look and feel (when cold) of the heat shields around the exhaust and all the hangers. > > 2) Its been quite cold and rainy off late and my car is parked outside. > So thats bad news right there!

I suspect the "jerks/hiccups" are related to question #1 and is the fuel pump-fuel filter. Good Luck > > please help, > dg. > -- Joseph Meehan Dia duit |

Yes it could be a saggy hangar. >> 2) Its been quite cold and rainy off late and my car is parked outside. >> So thats bad news right there!

The white is nothing but steam. It's normal if it's coming from condensation in the exhaust burning off, esp. this time of year. If you are losing coolant though that's a BIG problem b/c it's getting into the cylinders. However this time of year with damper/colder weather it's usually an ignition problem like old/cracked plug wires and old distributor cap and rotor. Replace those items...not too expensive. |

Replace those items...not too expensive. Good point, I failed to think of. I suggest that the ignition system should be checked first as it is almost always cheaper to fix and likely due for maintenance (tune-up) anyway. -- Joseph Meehan Dia duit |

When the rear shocks on my Fox were worn out (and then some), the rear
end would do all sorts of interesting things like shudder and growl and throw the back end around. But I would replace the fuel filter first and see what that does. |

But I would replace the fuel filter first and see > what that does. I second that. What care are we talking about here (did the o.p. say?). If it's a Mk2 Golf/GTI/Jetta they're known for bad in-tank fuel transfer pumps. The OE one made by VDO is usually the one that goes bad. The replacement Pierburg one is preferred. This pump isn't too pricey...I got mine from http://www.germanautoparts.com. The main fuel pump under the car usually doesn't go bad. That one is a lot pricier too. |
