What causes an engine to stall at idle?
If the engine stalls while idling or driving, the engine may be running out of fuel or not receiving enough fuel pressure to keep it running. The most likely cause of this kind of stalling would be a fuel pump that is not spinning fast enough or is intermittently cutting out.
starting on very cold mornings ,the engine will run at high rpms (just like you have a choke on) and then will after a minute or two return to idle rpms( most cars is around 850-900)
If you have a hydraulic clutch and you have never changed the fluid then I suggest that you have it done as the fluid is probably freezing the water content in it ( brake fluid is hygroscopic-- attracts moisture from the air)
Check the linkage adjustments for dirt and other foreign objects stopping full movement or if the lever is direct into the top of the box then check the gear lever pivot at the top of the box for loose or adjustment.
If you have a cable clutch ,consider replacing the cable.
Sounds like the sending unit has an intermittent short to ground. Unhook the the wire from the sending unit, and see if the needle stops jumping around. If it quits jumping around, replace the sending unit. If it still jumps around, you have a bare spot somewhere on the wire and it is hitting ground which will cause the needle to jump. Cut out the bad part of the wire and splice in a new section. That should fix it.
It sounds like your transmission is going into the limp mode. The transmission goes into limp mode to protect the transmission from major damage. You either need to take it to the dealer or to a transmission shop to have a diagnostic test done.
The only way to find out what the problem is is by doing a scan of the car computer module using an OBD code reader. The codes returned will tell you the cause of the problem.
Your problem sounds as if the thermo sensor....which controls the air
fuel ratio when engine is cold....is faulty. It is a common fault on
this model.
This is not an expensive part, and takes only a short time to fit.
Good luck
