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.

Crankshaft Positioning Sensor Replacement
Problems with the Crankshaft Position Sensor (CPS) on Mercedes-Benz cars are fairly common. If you have been experiencing stalling or no start conditions, a failed crankshaft position sensor is often the problem. Your CPS may have failed if the engine cranks but it will not start. At first, you may experience no start conditions intermittently. As the crankshaft position sensor fails completely, the car will no longer start or will die when you are driving. Starting problems are initially random, but more frequent when the engine is hot. Other symptoms of a failed crankshaft position sensor are poor acceleration, engine vibrations, poor throttle response, bad fuel economy, hesitation, engine stalls. The engine starts if you let it cool down. If you are stuck on a parking lot and the car will not start, let the car cool down at least 30 minutes and then try again. ( Thanks to MB Medic)

Silencer problem xcd 135


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.

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.
