JIBBBY Posted September 10, 2007 Share Posted September 10, 2007 Sounds like you have a poor idle....Change the air filter and spray out the throttle body and that should help the idle... If you stall then it could be something more, like a clogged fuel filter, electrical sensor problem.... Any dash lights come on, and how does the car act around town? Does it stall at red lights? We need more info...Maybe get a computer diagnostic check as well... Quote Link to comment Share on other sites More sharing options...
UCF3 Posted September 10, 2007 Share Posted September 10, 2007 It sounds like a tune-up issue-like Jibby mentioned. Can you find out when was the last time the car had a tune-up? A bad alternator, a blocked fuel rail also does something like this. Let's start with the Throttle body, tune-up, and if you have a AutoZone near you-you could ask to see if the Alternator is still good.

dashan Posted September 11, 2007 Share Posted September 11, 2007 Bad MAF sensor. Quote Link to comment Share on other sites More sharing options...
jrckelley Posted September 11, 2007 Share Posted September 11, 2007 I am in Austrlia and had this same problem. After getting the run arround from mechanics I had a go myself and found a crack in the Air intack tube behind the MAF sensor (sucking in more air than it thought it was). replaced the cracked section of Hose (rubber elbow thing) and all fine now.

That should fix it, be care full with the Mass air flow sensor. Quote Link to comment Share on other sites More sharing options...
