I just finished changing my coolant hoses and reinstalled the intake. Went for a test drive and my brakes are extremely stiff and hardly stop. My PSM faulty light came on and also the check engine light. Is there a hose I missed or pinched or a plug not plugged in? Please help. Frusterated.

Check for a vacuum leak. The power assist brakes need vacuum to the booster. If you're not getting any assist (hard pedal) it is possible that you have a vacuum leak. Since you have replaced the coolant pipes (removal of the intake etc...) you have have either missed a vacuum hose or have a vacuum leak at the intake thus the high rpm's.

Probably just a hose is off. Try to trace it from the brake booster first before you disassemble anything.
