How to correct an aftermarket air filter from causing improper air/fuel ratio and misfire?
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?
As long as all the sensors are still in place. The only thing a filter can do is limit the airflow. This is not a carburetor, it is fuel injected. The computer will make sure the A/F is correct.
Is there a solution(s) to correct this?
if it incorporates existing sensors and their positions, sounds like it's too restrictive for the flow rate needed. Odd, because they usually provide better flow, but engines, in oem form, typically can't take advantage of any increases in air flow rates. Which is why they are merely bling as they are not tuned for a specific engine app. The system that was on it IS!
solution would be to remove it. Put the oem system back on. You already know they are simply bling w/o tons of other mods.
I have no idea but hopefully someone does
- I have a 1997 ford windstar and it over heated and now has milky sludge in the air filter drum? Car over heated no coolant filled coolant. It drank two full bottles running very rough miss firing and now there's a milky sludge blowing back through the air intake…
- Can an aftermarket air cleaner on a ford focus 03 cause an obd p1440 evaporative system code leak? Looking to buy a for focus 03 hatchback. Owner claims he has been driving on a check engine light for two years that reads p1440. He claims it is because past owner put an aftermarket air cleaner in and can't get rid of code. But p1440 is an evaporative systems leak like your fuel filter or emissions etc. Is this possible. Also would you buy this car if this guy drove two years on that check engine light. Is it really much to do about nothing. He claims car runs great.
- 2012 Ford Fiesta has no air pressure, brand new air filter? Not sure what's going on with the wife's car. Hot as hell outside but her ac blows like it's on the lowest setting when it's on full blast. I changed her air filter but it didn't help at all. Do these have a cabin air filter? I tried finding out online but can't locate it from the passengers side where they say it is.
- Why Does Replacing Idle Air Control Valve on 2002 Ford F150 not correct Idle issue? Got A check engine light. Code said Idle Air Contol Valve. Purchased A control valve at parts store. Replaced control valve with new one. Engine Idled up real high. Attempted driving, thought computer had to reset. Engine still idled up too high. Parts store said vehicle had to be driven for at least 20 miles for control valve to operate correctly. Drove truck 30 miles, engine started to surge. Put old control valve back in and engine does not idle high or surge but stalls out.( suggestions) ?
