rockfangd Posted August 26, 2009 Report Share Posted August 26, 2009 Ok so my 2000 lumina seems to have some trouble on startup when it sits for a few hours. It starts and immediately stalls. If you tap the throttle it runs fine but if you let off of the throttle the lights flicker and it feels like it is idling too low. sometimes i have to restart it 3 or 4 times but once it is running it will not stall. and once warmed up it starts fine also. I dont really know what the first thing should be checked. No SES light. I was almost thinking IAC, or possibly TPS. Fuel pressure reads 42 at key cycle and 45 while running. I dont know i am too tired lol Quote Link to comment Share on other sites More sharing options...
