When start and engine comes to operating temperature the idle starts to drop up to 400rpm and dies on neutral & parking, changed ignition module,idle air control valve, throttle position sensor, pick up coil, adjust timing and still the same, I encreased the rpm but when I put it on gear dies, help I'm spending too much and can't find the trouble. Thanks

. Check for codes.

. Check the Electronic Spark Control Module, AutoZone, ESC100.

. Check the coil.

Thank you txgreasemonkey, but I solved the trouble it was a faulty distributor, plcd nw and no trouble.
