1985 Chevy Camaro fuel

White smoke indicates a blown head gasket. The white is water burning. You might check to see if you are loosing radiator fluid. You can also pull the plugs and check for water in the cylinders. Also pull your oil dip stick and see if you have water in it and you can have oil in your radiator.

Hello, I would not go out yet and get a regulator. There are many reasons why it may be doing this. You put larger injectors in. This requires more fuel, not necessarily pressure but fuel. Some of the mustangs use “Boost a Pump" to increase the fuel. You can read about that on the web. Also remember, the other sensors are reading data and getting it to the PCM to tell it what to do. It may not be able to understand the fuel/air ratio mix and or is not allowing any more fuel to be supplied. Though sitting and adjusting it will give you results, screaming down the road with your hair on fire is putting a totally different demand on the system. Does it have an OEM fuel pump on it? If so that pump may only be able to put out enough fuel to keep the normal injectors supplied. I suggest you talk to a local speed shop that specializes in increasing horse power before you spend money on another regulator. The cost of the speed shot visit may save you lots of time, money and frustration in the end. I have attached a link for you to review also. Hope this helps. Good luck. Have a great day and thanks for visiting us.
