1. Remove the airfilter box and try to rev. it up but dont yank it up rev it up in a 3sec time interval from 0-9000rpm. If it revs up replace your airfilter it might look ok but the material it is made of ages and with damp in the air closes up the micro holes in it and chokes the engine as soon as you rev it up. If you have an airbox don't fit those smaller individiual airfilters you would have to get it jet dynoed, what I am saying is fit the same type air filter back on or you will have fuel air problems.
2. Remove the exhaust manifold from the head, start it up and rev it up in a time interval of 3sec from 0-9000rpm. If it revs up your exhaust is blocked and you either have a wasp stuck in your exhaust outlet or it is aged and blocked. Try closing your mouth and nose with your hands and breath in or out, this is the same with your engine.

3. If this does not rectify your problem you will have to look at your carburator float levels or your coil packs. Let me know if it work or don't so that we could fault find your problem this is the easiest and the firts steps to follow.

Not really. Likely the ceramic catalytic converter element has broken loose. If you get a blockage, you'll fry your exhaust valves, maybe hole a piston. Replace it.

Try removing the vacuum line to the power brake booster and putting you foot on the brake to see if it cuts out.. I suspect a air leak in a vacuum line somewhere that is causing the air fuel ratio to change and the engine is stopping because of this. Another thing is to check the idle rpm because if this is below the required 900 rpm then when you accelerate and the ac cuts in it may be what is stalling the engine.. Also have the cat converter checked as they break apart and block the exhaust pipe which will cause the engine to stall.

Myvw polo keeps cutting out lots of fibres coming out off rear pipe

The fibres coming out of the tail pipe would be the glass wool coming out of a muffler which is breaking apart internally. Whether this is the reason for the engine cutting out is difficult to say. It is possible that the glass wool is restricting the exhaust to the extent that you are not getting sufficient evacuation of your burnt gasses or it is upsetting some of the sensors. Have the muffler problem attended to and see if that makes a difference to the engine operation, and then take it from there. If you find this helpful, please rate the solution.

I hav 96 toyota cavalier auto,it shuddered and

I don't know if it would cause the shaking and vibrations, but for the smoke it could be loose nuts or broken studs on the exhaust manifold -- when engine is cold check each of the nuts (there should be 8) to see if they are loose or missing/broken; you may have to remove a heat-shield in order to gain access

1990 1.9 escort will not run over 15 to 25 mph i pulled the codes and got code 37 if i am reading the flashes right

It sounds like a blocked exhaust pipe , try reving engine an feel the pressure that comes out the rear exhaust and take note of engine revs then compare it with another vehicle. if you feel its weak you can try disconnecting front pipe from the first silencer/ exhaust and then do test again and see where reves go to , No need to over rev vehicle.
