Ok....It runs Fine once you get it out on the Highway..

When I first got it...it would Die out...after about 40 seconds of Idling..it would Idle...then get rough and die out......and Die out when you apply small amounts of gas..such as backing up and pulling in or parking...if you werent applying a lot of gas it would kill out..So everyone told me..Fuel Filter....and I haven't got that checked yet...BUT...the car isnt being Driven at the moment..and after a month or so...it now dies out almost immediately if there is no gas applied...it will idle for a few seconds...get rough..and kill out..and someone told me that the Fuel Filter wouldn't have gotten worse if it wasnt being driven...So what do you guys think...Fuel Filter...or more serious?

Could be a fuel pump.

i would go ahead and replace the feul filters, (cheap route first),as it sits for a month crap settles due to gravity in the filter and clogs more, my old truck did that and that fixed it, the are 2 filters, up front by moter and one uder the car by gas somwhere. DO BOTH, there about 5 bucks apeice. just try that the if its not solved go to the fuel pump or the injector.
