Is there something to help engine warmup in electrical system.starts up runs for 5 to 10 seconds then starts spluttering then stalls .once you peersist and warm up,runs fine can you help.
Try to reset the IAC valve on the throttle body it has 4 wires t it .
procedure is as follows
turn ignition key on (don't start the engine), unplug the IAC valve, turn the key off, replug the IAC .Do this 3-4 times .Then start the engine while holding the pedal down at about 2000 rpm then let the rpm down slowly till idle. Sometimes the throttle requires cleaning then redo the reset.
