Hi, I have a 96 grand prix se and once the car is warmed up and say I'm sitting at a red light it starts sputtering like it doesn't want to stay running any ideas?

That's the weird thing there is no check engine light on or any warning light for that matter.also I actually replaced the fuel filter & plugs yesterday thinking maybe that was it.. It only starts acting up way after the car is warmed up and only when I'm idling. I haven't fully let it stall,when it happens I just either put it in neutral and apply a little gas or keep it in drive and just apply a little gas til the light changes.....if you have any ideas please let me know thanks That's the weird thing there is no check engine light on or any warning light for that matter.also I actually replaced the fuel filter & plugs yesterday thinking maybe that was it..

try disconecting your egr valve then test drive the car ok most likely you have a sticking egr valve try then let me know ok try disconecting your egr valve then test drive the car ok most likely you have a sticking egr valve try then let me know ok

So you know how you asked me if the check engine light was on,well i drove to the store real quick and now the check engine light is on so do you think it still could be the erg valve?? So you know how you asked me if the check engine light was on,well i drove to the store real quick and now the check engine light is on so do you think it still could be the erg valve??

did you disconect the egr before you drove is yes its normal for check engine light to come on question if you did disconect the egr did it stop doing what it was doing did you disconect the egr before you drove is yes its normal for check engine light to come on question if you did disconect the egr did it stop doing what it was doing

or if you dint disconect the egr an check engine light came on by its self then what you need to do is get a code reader or go to auto zone an get codes or if you dint disconect the egr an check engine light came on by its self then what you need to do is get a code reader or go to auto zone an get codes

from them and let me know what codes came out of it that way we go trait to problem ok let me know from them and let me know what codes came out of it that way we go trait to problem ok let me know

Ok I'll go to auto zone and get the codes and then we can go straight to the problem cause I didn't even unhook the egr valve yet! So when I get the codes I'll message you them. Thanks again for helping me out I just hope it's not something to big for me to fix:( Ok I'll go to auto zone and get the codes and then we can go straight to the problem cause I didn't even unhook the egr valve yet!

ok let me know and ill try helping you on geting it fix ok let me know and ill try helping you on geting it fix

Hey I went to auto zone n the guy said half of the motor isn't getting fuel when idle? Hey I went to auto zone n the guy said half of the motor isn't getting fuel when idle?

Ok I went back to auto zone n got the code it's P0171... Ok I went back to auto zone n got the code it's P0171...

YEA THAT CANT BE CODE PO171 MEANS HOLE SISTEM IS RUNING LEAN WHAT CAN COUSE THAT PROBLEM IS LOW FUEL PRESSURE A INTAKE MANIFOLD VACUM LEAK DIRTY FUEL FILTER YEA THAT CANT BE CODE PO171 MEANS HOLE SISTEM IS RUNING LEAN WHAT CAN COUSE THAT PROBLEM IS LOW FUEL PRESSURE A INTAKE MANIFOLD VACUM LEAK DIRTY FUEL FILTER

Ok I will check all that and I already replaced my fuel filter the other day so let me check the rest of the stuff and I'll get back to you. Yesterday the guy at auto zone said it might be this ari sensor or something so I got that and put it on and it didn't fix the issue and it actually ran worse so I put the old sensor back on...alright I'll get started on the issues and I'll let you know thanks again Ok I will check all that and I already replaced my fuel filter the other day so let me check the rest of the stuff and I'll get back to you.

WISH SENSOR WAS IT MASS AIR FLOW SENSOR OR OXIGEN SENSOR WISH SENSOR WAS IT MASS AIR FLOW SENSOR OR OXIGEN SENSOR

It was an idle air control sensor.. It was an idle air control sensor..

NO THAT WILL NOT FIX IT ITS GOT NOTHING TO DO WITH THE CODE P0171 SO JUST RETURN IT NO THAT WILL NOT FIX IT ITS GOT NOTHING TO DO WITH THE CODE P0171 SO JUST RETURN IT

Yea that's what I'm going to do! Alright I got a go get carb cleaner and I'll start I'll prob. get back to you around 11am or 12pm will you be able to write me back around then?

WHE WAS LAST TIME YOU DID A TUNE UP IT MEANING SPARK PLUS AND WIRES LOOK FOR OXIGEN SENSOR ON EXUST SISTEM DISCONECT THE WIRE TEST DRIVE CAR SEE IF IT GOES AWAY NOT SHORE IF THIS CAR HAS 1 OR 2 OXIGEN SENSOR BUT I THINK S ONLY ONE OK LET ME KNOW WHE WAS LAST TIME YOU DID A TUNE UP IT MEANING SPARK PLUS AND WIRES LOOK FOR OXIGEN SENSOR ON EXUST SISTEM DISCONECT THE WIRE TEST DRIVE CAR SEE IF IT GOES AWAY NOT SHORE IF THIS CAR HAS 1 OR 2 OXIGEN SENSOR BUT I THINK S ONLY ONE OK LET ME KNOW

YOU REPLECED SPARK PLUGS SORRY WHAT ABOUT SPARK PLUG WIRES YOU REPLECED SPARK PLUGS SORRY WHAT ABOUT SPARK PLUG WIRES

So last night I had to run to the store and I think cleaning the throttle body and the air hose and maf sensor worked because after driving it to and from the store I sat in the drive way and let the car idle and I haven't had to push on the gas at a light all day and the check engine light went off but when I did the tune up last week I was only able to replace 3 out of 6 of the plugs because 3 I couldn't get to I think i might need to take it to a shop to get finished...I did notice that when the car is idling now it sputters a little could that be because the 3 plugs need to be changed??
