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 da 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, step down harness, n a chipped p28 ecu. What can be the problem? Please help!!

 

Check to see if you have a loose vacuum hose for the revving, or the intake manifold gasket. Spray some crab cleaner in the manifold area and around vacuum hoses. For the brakes, you may be leaking brake fluid. Also check the brake booster hose.

 

Check your throttle cable to the throttle body it might be stuck open a little causing the engine to idle high like its reving from not closing correct. Also while the engine is idling high put some pressure on the the throttle plate where the cable is attached and turn it to its closed position, if the idle goes down either the throttle cable is too tight or the throttle body butter fly will need to be adjust by the little screw behind it.

You also seem to have a brake booster issue, If you couldnt push down on the brake thats a seriouse issue you need to further diagnos. bleed your brakes and see if that fixes the brake pedal issue. Thats scary man.

 

Thanks for the help guys! Im gonna check the car out now

 

Problems with the brake booster hose would create issues with idling and braking, I would suggest to look at that

 

It was the vacuum hose from behind the intake manifold to the brake booster. Plugged everything back up n its good as new. Thanks for the help honda tech! Def appreciate it!
