Driving to work today I saw a silver RX kind of random in the town I live in. Some middle aged lady smoking in her car . Anyways driving a long and I go to run by someone car makes a lowed hissss and only posts 5psi. I was like wtf, so I started testing it and I wouldn't get more then 4-5psi with a lowed hissing coming from the glove box it sounds like. I opened the hood when I got to work and didn't see anything but I am at work and couldn't do a real good check. If anyone has suggestions for me would be greatly appreciated.
