Asked by Jun 11, 2015 at 06:52 PM about the 1999 Oldsmobile Silhouette 4 Dr Premiere Passenger Van Extended

Question type: Maintenance & Repair

How do I fix this? Whenever I start

unless I step on the gas. Throttle

Hopefully this gets answered.  Its
my only ride...

scan the computer for codes. you could have a bad idle air control valve or throttle position sensor. also, when was the last fuel filter?

Ill take it to auto zone for the codes later. Last fuel filter is no idea. I plan on it. I wanna replace all the fluids and filters and have it looked over to make sure no suprises come up later. But anything I can fix on my own id love.

Remove breather to throttle body,open throttle plate to open position and spray it out with carb cleaner,car not running,if this does, not help you have to remove the throttole body and clean it off of car,there are videos of this on you tube.

Maybe a dirty injector try fuel injector cleaner that you put in gas tank.

I will. This van is my baby. I gotta take care of her. So do those cleaners actually work?

21,670

Yes they do. If that is your problem it will take care of it.

Ive given it one bottle. Is the effect instant or should I give it more over a period of time?

21,670

Have to drive around or let idle a while so that it can work on cleaning the injectors.
