Hey im new here and have been a member on z28.com for a while but i figured this would be a better place to post my question snice this is a thirdgen board ok... When I start my car it runs fine and will for the first 2-5 minutes? then for a period of about 30 seconds up to 3 minutes or so it acts like its getting fuel then the next second its not then it is again and isnt again.. and sometimes the car will almost come to a stop if you go WOT its will act like its not getting fuel even worse but if you feather the gas it stay running then after its done this it will be ok and will not do it again except sometimes sitting at a light/stop sign but if you stop and put gas in the car it will repeat the process also if you just turn the car off and turn it back on it will not do it again if you do not leave it off for a longer period of time sry for the long first post but i just really want to get this figured out its my daily driven car

 

Could be the fuel pump on its way out...welcome to the board!!

 

Thanks im impressed with how fast people reply on this board I though it might be also but ive owned the car 9 months now and its always done it and I figured the fuel pump would went out by now if thats what it was also forgot to add I replaced the fuel filter and my dad rebuilt the injectors I just figured I need to get the problem fixed now plus its imbrassing when friend rides with me and it starts doing it and jerking you around in the car

 

I would check the fuel pressure.. if you can ,get a gauge that you can lay on your hood , so you can see if it changes when you drive,

 

ok thanks I will try to do that this weekend also a while back somebody told me it could be a egr valve?
Thanks,
Chris

 

Are you getting the service engine soon light and if so, what codes are you getting?

 

Nope im not getting any trouble codes just 12...
Thanks,
Chris

 

I might have read wrong, but it sounds like a vacuum leak to me. Sounds similar to how I'd describe one.

 

yeah I have looked at my lines b 4 and they look shot

 

did the car do this before the injectors were rebuilt ....????

 

I'm still thinking fuel delivery.. If you had a carb with vaccuum advance disrtibutor then maybe vaccuum.

 

Yes its done it the whole time ive owned the car thats why we rebuilt the injectors but it didnt work
Thanks,
Chris

 

I am going to replace the vacuum lines because I was looking at them today and some had tape around them and some were not even hooked up... does anybody have a chart to show were they all go
Thanks,
Chris

 

Look under the hood over your right shoulder as you are facing the car. There should be a label there with the emission (vacuum line) hose routing. If not, I can post one for you.

 

Thanks as soon as it stops raining im going to go and see if I can find it I love how fast the replies are
Thanks again,
Chris

 

Tape and all ,huh. Yeah this might be a good place to start...

 

Yeah im suprised I didnt notice it earler im planing on puttin new ones on this weekend hopefull this will help out some I noticed and idle varation when im in park or nuetrul but not when im in drive or anything else?
