SOURCE: 2002 Buick Rendzvous Won,t idle under 1000 rpm

This could be the TPS, or Throttle Position Sensor. Generally when there is an idle problem, this is the first thing to look at. Hope this helps

SOURCE: The engine will start and idle fine. Engine revs

Definitely an electrical problem. Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.

SOURCE: Won`t idle Dies a lot.

Try Seafoam,... purchase at Autozone $10 a can. read instructions. But i would just pour in half a can to half a tank of gas drive it around town for about 20 minutes and see if that wont clean up the gunk in you carb or injectors.

Starts but won't keep running then won't start


Check your Fuel Pressure and if that is good (over 40 psi)

then check your Idle Air Control (IAC) Valve

and seeing that it is a Mid-90's Chevy.. MAF Sensor is going bad.

If you UNPLUG your MAF and see what happens.... MAF is in the Air Intake with a 4 wire...

Drop the tank and on top of the tank where the wires go is a special sort of electrical gizmo that will not allow the pump to work unless it gets the right frequency signal so just bypass it and run the wires direct onto the fuel pump --sorted--
