Carb.? bad needle seat valve? Float needs adjustment?
replace the alternator
MX 6 Try your 02 sensor and check your cold start sensors If you have just replacrd coolant bleed the air out of system as tis will cause this symptom Check you ignition timing it may be too far advanced
Manual or automatic transmission?
Tune up time with fuel and air filters, spark plugs and wires.
Sounds like the throttle cable is broken.
