Question type: Maintenance & Repair

I bought a 92 Camry SE 3.0 v6 5 speed. It
been setting approximately a year. I put gas
and battery onit and drove it towards my
house. It is overloading so bad you can't see
the car behind you. What will cause this. I've
changed vaccum boxes, fuel pressure
regulator and just noticed leaking intake
gasket

When you say its overloading, I assume you mean its dumping fuel, if it is you will smell a rotten egg smell, or black smoke, which is unburned fuel. It could be a number of things fuel related. I would check for codes if possible. If nothing there check for a large vacuum leak where the computer may try to compensate, but check the fuel regulator, maybe its leaking externally. Take a fuel pressure reading, get one from your local parts store to rent if possible, this will give you an idea on the regulator. A stuck oxygen sensor can cause this too so, but it will usually store a trouble code in the computer. Good luck.

Smoking? What color smoke? Blue, black or white?
