Hi everyone I appreciate the wealth of knowledge on this forum and I wanted to ask a question. Yesterday I cleaned the EGR Channel on my 1995 Grand Marquis and I replaced the idle air control valve and the plenum gasket. I started the car and the check engine light is now off but the car is sputtering and backfiring through the intake and to top it off I have no brakes. The brake pedal is super stiff and I have virtually no brakes. What did I do wrong here?
