dmhoo29 Posted February 25, 2005 Report Posted February 25, 2005 I have a 1990 BUICK REGAL GS/3.8/ V.6/AUTO. When driving the car will be running fine,then it will jerk and then die. It usually starts right back up,and when you start it back it will run fine for a while like a around town a mile or so then do it again.It will do it when your slowing down to stop,or turning the corner.I have not checked real good,but it does not seem to do it while driving down the highway????????????? :bawl: Quote
94CutlassSLCoupe Posted February 25, 2005 Report Posted February 25, 2005 how new is your fuel filter? When I had my '88 CS, it used to stall when you put it in reverse....I changed the fuel filter out (costs like $7), put some gumout extra fuel injector cleaner in the tank, ran it hard for a tankful and it ran fine after that.

GP1138 Posted February 25, 2005 Report Posted February 25, 2005 Check the Idle Air Control Valve. Does it happen when you shift into drive, or reverse? You might clean it. Quote
dmhoo29 Posted February 25, 2005 Author Report Posted February 25, 2005 It dies only when I am going down the road, or when I turn the corner, or stop. When I'm setting still with it running it is fine. Quote
dmhoo29 Posted February 25, 2005 Author Report Posted February 25, 2005 o.k. i changed out the fuel filter.NOPE THAT'S NOT IT.TOOK IT OUT TO DRIVE AND IT REALLY DIED ON ME.THE MOTOR ACTED LIKE IT WAS GOING TO JUMP OUT OF THE CAR IT JERKED SO HARD.SO, I GOT MAD AND STARTED IT WHILE IT IDLED ROUGH,FLOORED THE CRAP OUT OF IT,I SHOOK NEARLY ALL THE BACK TO MY DRIVE. GOT A BLOCK AWAY AND THE DAMN THING STARTED RUNNING FINE?????????????????? helpppppppppppppppppppppppp TOOK IT BACK OUT AND THE SAME THING HAPPENED AGAIN Quote
cutlsp Posted February 25, 2005 Report Posted February 25, 2005 take it down the highway it should clean the engine and fuel lines out :? i normally drive for like 5 hours down the highway. if my cars start doing this sometimes it can be because i got bad gas. Quote

cutlsp Posted February 25, 2005 Report Posted February 25, 2005 only make sure you get a set from the junk yard if you can't afford the top quality coils :? Quote
GP1138 Posted February 25, 2005 Report Posted February 25, 2005 only make sure you get a set from the junk yard if you can't afford the top quality coils :? I advised him in a PM to go to the junkyard. Quote

HokemBokem Posted February 25, 2005 Report Posted February 25, 2005 It dies only when I am going down the road, or when I turn the corner, or stop. When I'm setting still with it running it is fine. So when your at a stop it dies. But when sitting still its fine? Quote

THe_DeTAiL3R Posted February 25, 2005 Report Posted February 25, 2005 I dunno if those engines have a MAF, if so maybe it's bad. You should clean your IAC (as someone stated above) and the TB, top engine cleaner. I say take a couple hundred bucks, go to the parts store and get everything you need to do a full tuneup. Quote
Brian P Posted February 26, 2005 Report Posted February 26, 2005 Yeah it's got a MAF, and they're known to go bad. As a minimum, maybe cleaning it would help. Quote
Robby1870 Posted February 26, 2005 Report Posted February 26, 2005 CPS wire grounding out to block randomly maybe Quote
dmhoo29 Posted February 27, 2005 Author Report Posted February 27, 2005 what's a MAF? and what's is IAC? Quote
GP1138 Posted February 27, 2005 Report Posted February 27, 2005 what's a MAF? and what's is IAC? MAF = Mass Air Flow sensor IAC = Idle Air Control the MAF senses the amount of air passing through the throttle body The idle air control controls the amount of air that goes through to keep idle speed specific.

3pt1lumina Posted February 28, 2005 Report Posted February 28, 2005 try the IAC... had the same problem with my 90 3.1 Lumina.. took me forever to figure it out but that did solve the problem. also, if the check engine light comes on, get that coded asap.. that may help you immensely if it ever goes on.

maybe2fast Posted February 28, 2005 Report Posted February 28, 2005 is it the TCC locking up and stalling the engine Quote
joberlee Posted February 28, 2005 Report Posted February 28, 2005 is it the TCC locking up and stalling the engine Good idea. Unplug the big plug on the front of the trans and see if it still does it. Quote
3.1LUMITIC Posted February 28, 2005 Report Posted February 28, 2005 another dumb question what the tcc my car is doing the same as his? Quote
Robby1870 Posted February 28, 2005 Report Posted February 28, 2005 TCC = Torque Converter Clutch. This little device locks the sides of the torque converter (one that the engine turns, and the other tranny fluid turns, which turns the tranny over) so that have the same angular velocity. Usually, when its not locked up, the tranny side (stator, I think) will turn a bit slower than the engine side, due to losses in the fluid that turns it. Locking of the Torque Converter gives better gas mileage because the engine rotational speed is more direcly related to transmission rotational speed. I can go more indepth, if you would like. I still think this could be caused by the CPS. Quote
joberlee Posted March 1, 2005 Report Posted March 1, 2005 TPS =Throttle Position Sensor, I think he meant he cleaned the IAC (Idle Air Control). Quote
Dannymik Posted March 1, 2005 Report Posted March 1, 2005 Yeah it's got a MAF, and they're known to go bad. As a minimum, maybe cleaning it would help. When I had my '88 Regal it would pull that shit when I would slow down for a red light and such...MAF was changed and the Regal was all better! Are you getting a SES light? Quote
