I realize the gain from an aftermarket cone air filter is minimal at best, but I'd like to have one installed on my vehicle. I've had them on other cars and have never had a problem until now. I'm currently driving a 1999 Ford Taurus, 3.0 (VIN is U), Automatic Trans, etc.
I purchased the filter and the an adapter for the air flow sensor from my local autoparts store (I believe both are by Spectre).
The long story is that I removed the old housing and installed the new components. Started the car and it stuttered like crazy! I was really worried it was going to misfire or kick a piston. It sounded bad. I turned it off quick. Reinstalled the OEM parts. Restarted the car and, apart from a momentary smell of fuel, it ran fine.
So, in short, I assume the aftermarket filter is causing an improper mix of air/fuel.
Is there a solution(s) to correct this?
