1994 88 royale LS jerking and dying on me
It started out small with the car just stuttering right around 52 mph when i was accellerating. it continually has gotten much worse. its not horrible, it doesnt jerk whenever i accelerate. also, it started dying on me. this has also gotten much worse over the past couple months. the rpm's just drop so low that it dies whenever im coming to a stop or slowing down. I have changed the air filter, fuel filter, plugs, wires, and iv had the fuel injectors flushed. nothing seems to be helping. what could it be? thanks guys i appreciate it

If you put the car in neutral before coming to a stop, will the engine die? Try this & post back.

Re: 1994 88 royale LS jerking and dying on me
on a trip where i made 14 stops, it died 3 times when i tried stopping normally with the car in neutral. which is the same as when it was in drive and i tried to stop.

Re: 1994 88 royale LS jerking and dying on me
ill try that. but yes, i have changed the fuel filter, checked the fuel pressure when i had the injector flushed. and we couldnt get the car to communicate with the machine so therefore no codes.

Most scanners will not work here, however the GM "Tech-I & II, Snap-On MT2400, (with correct key) Actron CP9140 & CP9150 will work. Try your local Advanced Auto Parts, they sell Actron scanners and some of them use the CP9140 to test customer cars. I use a Matco Tools 9640B professional enhanced scan tool on the 94-95. It has the 16 pin OBD11 connector and reads the OBD1 model specific codes, as well as Global OBDII codes.

Re: 1994 88 royale LS jerking and dying on me
Hello, I know this post was from years back...but in case anyone else needs help:
My olds 88 had a (somewhat) similar problem..only I could not get it out of my yard without dying when I let off the gas. Check your battery cable ends for to see if they are dirty and/or corroded. We cleaned mine and my car is back to his normal self and no longer dies. |
