My 91 model 22re 4 cylinder powered 4x4 pickup idles eratic ,the engine acts like it surges up and down and is worse when the brake are used .also the brakes are real spongy feeling but the master cylinder checks out ok. you can pull the big vacuum line on the throttle body ,right in front of the idle sensor and it will level out. I cant seem to figure what is causing this and is about to make me do something drastic like buying a ford or chevy !Please help I love my Toyota
Thanks, James
