Question about 1995 Oldsmobile Eighty Eight

1 Answer

Car stumbles,hesitates,loses power on Hwy, randomly

Hi, my 1995 Olds 88 runs great. But on some few occasions, for no reason, the car starts to stumble, hesitate, lose power, "check engine" light goes on, and this will continue until the car is stopped. On idle, the engine runs smoothly. The problem goes away when the engine is turned off, then re-started again. "Check engine" light then goes off. Tha car also stumbles and hesitates when starting cold and driving immediately, but corrects itself after a minute.
Is this the injectors? Throttle position sensor? Coil?

    Thanks, ccn7, but I have a new fuel filter and air filter.

    Thanks, noodle1985,no I haven't checked the electrical ground. Where do I start? Battery connections are good.

    I have to clarify that when I start cold, the car runs smoothly until I drive off. It'll stumble for a minute, then correct itself. To avoid this, I have to be easy on the gas as I accelerate.

    Try a new fuel filter.

Sounds like an EGR valve sticking. Start the engine cold and let it warm up. As soon as it starts to hesitate/stumble, pull the vacuum hose off the EGR and if the engine maintains a steady idle, replace the EGR valve. The EGR is sticking intermittently but it won't be long before it sticks all the time and you won't be able to keep the car running when it gets warm. This is an easy diagnosis, removal and replacement for the do it yourself car owners. Please rate me on my answer.

98 Corolla stalls or stumbles when cold

It sounds like you may have picked up some small debris from the bottom of the gas tank when you ran it empty. You may need to run a fuel/injector cleaning solution through the next tank of gas to clear the debris and consider changing your fuel filter too. Sea Foam is a great fuel additive and I recomment trying it full strength. Hope this helps!
