I just bought a 1995 240sx se with a blown head. I bought a remand head from a company in Dallas named ADC. These guys SUCK! They sent me the wrong head to begin with and when they sent the second head it had two intake cams in it. Good thing we looked. When we put the head on we had to shave the timing cover because they shaved the head to much. Now the car will start but has a rough Idle and will kill when you hit the brakes while driving. It sat for only a month so I don't think the fuel is bad. I'm Starting to think the head is just bad. I NEED HELP!

Any advice will be greatly appreciated

 

go to a junk yard and get another head.

done.

 

I'm really trying to get some advice. It may not be the head. Has anyone had this problem before? The car runs fine when excellerating. so if it was the internals it would run bad all the time right?

 

did you do a compression test?

did you kill a cylinder?

or did you not do the timing right or forget some vaccum hoses?

 

check for vacuum leaks areound the intake and throttle body... it sounds like this thing is sucking some major air somewhere... if it was a messed up head or timing it would run like a$$ all the time not just while on the brakes...
