It’s been about 2 years now, but I got the old girl running great again!
I had to change out the fuel pump and in-tank rubber hose attached to the fuel pump. I got most of the dash back together, at least enough so I can drive it. I found where my massive vacuum leaks came from and fixed it. The Dorman rubber caps I put on to cap off the large vacuum ports under the top intake cracked. One cracked so bad it was almost in half! I replaced the ignition switch. And I replaced the Mega Squirt computer with a Speed Density Mustang computer.
It was running so good, I had my wife follow me around town. She said the car smelled like it had ‘alot’ of exhaust. Not rich, like too much gas, but a really strong exhaust smell. I pulled away from her at one point, but she said she could tell where I was by following the exhaust smell. She also said if I wanted to do myself in, just start that car in a closed garage and you’ll be gone in a minute!
I looked the PCV system I had set up and realized I didn’t have any fresh air going into the system. I put on a breather filler cap and routed the PCV valve to a catch can and then to back to the intake vacuum. No more smell.
But I got to thinking about the PCV system. This setup is working for me now as I’m running Speed Density, but what happen if I convert to Mass Air Flow? Would it be an unmetered air source? Or is the amount of air so small the MAF computer will adjust for it? If not, what is the proper setup for a MAF PCV system?
I still have many items to fix on the car, but its great having her on the road again!
