Installed a cold air intake and car will start but won't stay running .

Put the STOCK breather system back on the car! .. It is a proven FACT .. the cold air intake.. breather tube/filter kit.. alone, does absolutely nothing to increase horsepower or fuel mileage... See YouTube video of 'professional' Dyno testing... BOTH WAYS! .. (There's one born ever minute!)

The MAF sensor needs to be incorporated in the system or the computer system will cut the fuel.

Bring everything back to stock Why do you need a cold air intake? Your racing or adding a turbo?
