  • Car is really messed up!! Please help!!

    Yo my cars f*cked up. I did a pull from 1st to 2nd and when i went to hit the brakes i cudnt depress the pedal. Had to stop wit the ebrake. When it came to a stop the car keeps revin by itself to 3000. I disconnected the ecu plugged it back in n the cars still the same. The car has an obd2 gsr motor, step down harness n a chipped p28 ecu. What can be the problem? Please help!!

    sounds to me like a vacuum issue maybe with your booster or something. check all vacuum lines going to your brake setup. also any leaks?

    brakes are just a hydrolic setup so if the pedal dosnt depress it means the pressure is going somewhere else..

        Yeah, sounds like the vacuum line from the intake manifold to the brake booster has a leak or is disconnected or something. If that hose is damaged or disconnected it would cause a vacuum leak which would cause the engine to rev high and it would also "de-power" the booster making it very difficult to apply the brakes.

        Keep in mind that your brakes still work if this is the problem, you just need to push on them a lot harder for them to work. It will be safer to stand on the brakes as hard as you can vs trying to use the e-brake - or better yet, try both if you need to.

        You may also want to check your engine mounts, if this happened when you were doing a full throttle pull the engine may be moving around too much and this could cause the booster hose to break or come off. Just a thought.
