    Bobby, try something else I advise to confirm whether the problem is there beteen servo,vacuum hose or one way check valve. Having the engine not running,take a seat on the driver's side,pump the brake pedal till it become stiff,then having the pedal presseded start the engine and see whether the pedal just moves a bit down or not. If you have a slight move then the servo, the one way valve and the servo hose are serviceable,you have to go to something else. on the other hand if you still have a stiff pedal,means that something is wrong between the above three mentioned parts. Check if you have any crack on the hose connecting the servo.

What will cause my car to run rough with little power while in reverse or drive when in park it runs and idles good but it takes a long time to get up speed.


motor mounts and transmission mounts will cause it to be rough while in gear, try power brkaing while in forward and reverse, power braking consists of pressing on the brake while applying gas, if you hear a clunk and hear it you have bad mounts

1998 4Runner - rough idle, engine light on (blinking, at times), sometimes when I step on the brake it brakes quickly rather than to a slow stop


The first thing I would do is to go and get the service light checked out. You can go up to an auto parts store (Autozone, Advance Auto Parts, or O'Reilly's) and they can scan your truck's computer for the trouble codes. This can really help in shedding some light on why your engine is idling roughly, although sometimes a rough idle can be caused by little things like bad fuel or needing a tuneup. As far as your brakes go, it is a good thing that your brakes stop your truck quickly. It is when your brakes slowly stop your truck, you should start to worry. Just adjust how much pressure you apply to your brake pedal.
