1985 VW Cabriolet

After starting my VW 1985 bogs down on occassion. I have newer injectors,fuel filter,gas tank, spark plugs. I t seems to do it more when it is cold. When I turn off the key a few times sometimes it seems to restore to normal or after barely driving for awhile. I checked for vacum leaks but to no avail? Any ideas?

Possibly a clogged catalytic converter. Even if it is clogged it can be irratic. I had a muffler shop check it by cutting a hole before it with a torch, changed it out and i was good to go.

Maybe it's your fuel tank that has contaminants -use a pressure hose and blow back the fuel into the tank, remove the fuel tank and flush out - could be rust as well. Hope this helps...

1987 vw cabriolet idles up and down. When you accelerate it bogs. If you come off gas pedal a little rpms pick up. Has new distributor, coil, fuel pump, plugs and wires. Also cold start vavle replaced....


At that point, I think the best thing to do would be having the carburetor taken off, take it apart, put it in some gunk remover (Carburetor Cleaner sold in 1 gallon barrels), then wirebrush it all out, make sure all the jets are clean, buy a carburetor repair kit, and put it all back together with new seals. At how old your car is, it would probably be best for it. On the cheap side, all that needs to be done is having the carburetor's throttle accelerator pump fixed (Squirter). A shop should be able to do all this, but it's not hard, either.

1985 VW Cabriolet cranks fine. Timing belt intact. Was running yesterday, then just stopped. Spark to distributor, no spark out. Replaced fuel pump relay, distributor, ICM, cap and rotor. What else...


That is very interesting.If you have spark to the distributor means that the coil and a CP sensor are OK.Than you have to check ignition leeds and a spar plugs.Did you put correct rotor and a distributor cup?Check compression of the cilynders

Car doesnt accelerate when gas is pressed it bogs and jerks motor is on but idle is low


This problem could be caused by anything between
the gas pedal and the throttle. Talking about spark
plugs, air filter, fuel filter, fuel injectors, engine control
unit, egr system, intake manifold air leak and so on.
You can try Spark plugs or a couple of bottles of
gas tank additive to clean you fuel system. Had a
98 with dirty injectors which took five applications
to clear them. Other wise Chrysler will have to hook
up and look for fault codes. If no ck engine light is
on try the simple fixes first (basic tuneup).

My 98 civic ex sometimes hesitates just a bit bewtween 2-3k rmp but only 70k miles on it. Checked 1 spark plug looked ok.


Make sure all spark plugs are sparking.You cant tell if you have a faulty one by looking.

1993 VW Cabriolet Fuel pump or Injector problem?


Hi. This is more of a fuel filter issue than a pump issue although, a bad fuel filter will eventually destroy a fuel pump. When the filter is restricted or clogged, this will tend to work the pump harder than normal. this will over heat the pump, therefore, shortening its life span. I recommend replacing the fuel pump and filter and, adding a fuel additive like techtron fuel injector cleaner/water remover as well.

Please rate and have a great day:)

Start and stop


Top candidates for this problem are:
Clogged Fuel filter
Faulty Fuel pump
Clogged fuel injectors
Dirty / worn spark plugs

Of these, only the clogged fuel injectors are likely to respond to a gas tank additive, and even then you need to get the right kind of additive.
If your fuel filter has not been changed in a while (couple years), start with this. It is fairly easy to change. The fuel filter is under the car near the the driver's side rear door.
If this problem started "suddenly," then the fuel pump might be the culprit.
Fuel injector / spark plug issues are not likely to stop the engine right away, but would tend to cause it to miss cylinders, idle rough, or start rough.

Bogging down when accellerating


Sorry to say, a battery and alternator would not affect your engine like that. You would either not start, or start and then just shut off, not bog down.

If your VW is a diesel, I'm sorry I don't have any answers for you. Diesels are very unique creatures that require very unique people to work on them.

If it’s a gas engine, start by changing your plugs (Bausch parts only please when possible), air filter PVC valve, spark plug wires. Also does your engine have a distributor and cap if so replace both along with the rotor. By the way, these are all basic tune up parts. If you don't know if they have been replaced, then they probably are all original parts. And luckily other than gapping your plugs nothing I have told you to do will require a degree or any experience. The people that sell you the plugs can gap them for you for free. Or if you choose you can get Bausch Platinum 2 Spark Plugs. These do not need to be gapped, and can be put in with no adjustments. Also put a can of BG44K in the tank, it will clean out everything where the fuel goes. Speaking of fuel, change your fuel filter. Check to see if your car has more than one fuel filter. Some cars have 2. A clogged fuel filter could cause a lot of the problems you are having also. Everything I told you to do first will also give you BETTER FUEL MILAGE.

If none of these things work, you need to take the car in for diagnostic work because most anything beyond this is probably going to be more than what you want to get into. If you’re not afraid get a Haines Manuel or a Chilton, and get greasy my friend.
