90 5.8L Idle Issues

My 90 bronco with a 5.8L EFI is acting up. At idle the rpms fluctuate pretty derastically. It also will shut off if trying to leave from a parking space or something like that when the engine is using more power for the power steering and stuff. Anyone had an issue like this before?

could be a vacuum leak, test the intake gaskets with carb cleaner. Spray it on the intake gaskets and see if it idles up. If so then you have found your problem.
