Question about 1999 Volkswagen Golf

1 Answer

Lack of power

I have a 99 golf. the problem started of by losing power at about 65mph. once it reached that speed it would cut off to about 50mph then i would be able to accelerate to 65-70mph. now driving off is difficult. it is very slugish and hesitates horribly. turning on the car is not a problem. i just can not accelerate. i have changed the o2 sensor but problem persist.

    i have changed the fuel filter. never messed with the fuel pump. although, when refueling, i would hesitate to turn on. meaning i would have to crank it a couple of times and assisst by pushing on the accelerator. can it be related? the air filter seems to be fine,

There seems to be some kind of fuel (gas) starvation, check the fuel filter, check to the fuel pump could be weak.
Check the spark plugs, the condition of them will give yousome direction to go about it all.
If its whitish =lean means lack of fuel (gas) and by your explanation it should be whitish.
If its a carburator model thn it may need cleaning.
Not bad to check the distributor too.

Hope this helps!

When does the overdirve need to be turned on


Usually the overdrive should just be left on. It should only come into play when you are at high speeds above 50mph. This is essentially your "5th Gear" and should increase fuel economy. If you leave the overdrive "OFF" on the highway your engine RPM will be higher causing the fuel economy to suffer.

Engine is sputtering / cutting out. Especially once you get up to speed 40-50mph on the lower end of the RPM's, it starts to **** it cuts out so bad.


Is your check engine light on? If so, scan for trouble codes. Also, check for vacuum leaks, distributor cap & rotor.

Loss of power at 50mph + Engine and truck shake


I would check the fuel filter, it should be changed every 20,000 miles or so. Also I would check the fuel pressure at the test port. I would also check for a weak ignition coil.

Somewhere along the the line you may have a fuel blockage or a good dose of water in your fuel tank.Check the water in tank 1st.Add 1 litre of metholated spirits to every 20 litres of fuel.This will allow the water to break down and be burnt through the motor over time.Do this twice.If this does not work,there may be a glob of **** in the fuel tank that blocks the pickup.If this is the problem,the tank needs to be taken out and cleaned.I hope this is a start to get you back on the road.

check the mass airflow sensor. When bad, there is reduced power and the computer uses a default setting
