SOURCE: runs rough when cruising at 35-40 mph

try pulling off the air breather hose and look inside at the mass air flow sensor,it looks like a wire with a diode hooked to it incase you didnt know,see if there is any fuzz on it,sometimes the air filter will lose small pieces and the mass air flow sensor catches it.If that doesnt work then you may have a fuel problem,weak pressure,causing the mass air flow sensor to read too much air so it tricks the computer to adjust the issue.

SOURCE: TOO LEAN CODES

yes very very common code for these motors i get them all the time. now the first thing i do is listen to the pcv valve for noise if it is rattling this is the problem and is the most common of all. another thing is the intakes leak from cracks in them but the only way to find it is with a smoke machine. now the one other thing i have seen before is debre like a leaf in the mass air flow sensor but you have replaced it so most likely no that.

do your self a favor and change the pcv valve it only cost under 5 dollars. if this is not it you will need to find the leak in and around the intake or a vacuum hose.

because you have two lean banks this mean if it is a leak then it has to be in common with both banks and that is the vacuum line system intake etc...

let mew know if you have any more question. good luck man

Sound like you have a big vacuum leak. Check the hoses that attch the PCV valve on the valve cover on the passenger side. Also reach way back on top of the engine there's another hose there that is known for going bad. The dealer has those hoses and they call it the Heated PCV valve hose assembly. Very common problem.

SOURCE: i have been having problems with my 1998 ford

I have a 98 Windstar and it would die when pulling up to a stop sign, slowing when coming to a stop or making a slow turn. According to Ford recall 98E03 EMISSIONS RECALL some vehicles may stall during deceleration when coming to a stop, during slow speed parking maneuvers and/or coasting thru slow sweeping turns. This may be caused by the Powertrain Contro lModule (PCM) calibration dropping the rpms too quickly during deceleration. This involves reprograming the PCM. The revised calibration will allow the engine rpms to drop slowly during low speed maneuvers to reduce the possibility of a stall. Call your local FORD dealership (have your VIN handy) and have them check to see if this recall has been performed on your vehicle.

Low idle & vibration at idle


I don't know if this will help. Had a similar problem with a 99 Blazer.
Would drop to between 300 and 500 rpm at stop signs and red lights, would stall and shake.
Did all the same checks, replaced mass air flow sensor, replaced cam sensor, cleaned the fuel injectors but the problem was still there.
Replaced both #1 and #2 O2 sensors in the exhaust pipes and now the vehicle runs fine. The idle is back to a steady 750 rpm in all stopping conditions. The Mass air flow sensor and Cam position sensor get information from the O2 sensors.

idle control valve will need cleaning, also the mass air flow as well ( mas air flow cleaner only recommended) and the air temp sensor. may need cleaning or replacing, it could also be the spark plugs or leads. it could also need the egr cleaning as well, and sometimes it can be from were you get your fuel. if the garage you get your fuel from when its rain and you fill up and then have problems there could be water in the fuel as some garages don't know that ground water is getting into the tanks under ground.

I'm having the same problem. At first I thought it was bad fuel so I replaced the fuel filter to no avail. Then I cleaned the Mass Air Flow sensor which also didn't work. Is your check engine light on?

Car sputters or dies when idling, but starts fine.


I suspect you have an idle circuit issue. When the thottle is closed, the throttle valve is almost closed (like 95%). The linkage on the throttle body is against the hard stop.
SO, when idling you need a way to let enough air into the engine to maintain an idle speed. The IAC, Idle Air Control valve is the way you do that and the engine computer controls the rate of air flow.
Sometimes it gets plugged up so you can clean it with a little carb cleaner. Might have to take it apart.
Also, you have a MAF, Mass Air Flow sensor that tells the computer how much air is flowing through the air cleaner intake at any time. The sensor gets coated with varnish and vies a false reading. Clean it gently with carb cleaner and a toothbrush.
Other than that, I would go to an auto parts store that can run a computer scan for free to see if you have any fault codes stored. They will tell you next stpes.

I assume you 2.0L SPI engine & not Zetec.

The car stalls at idle and when stopping.


Sounds to me like an O2 sensor, i had a similar problem with my Ford Probe GT. Luckily my car was a 5 speed so i just kept my foot on the gas a bit and put my car into neutral as i was slowing down or coming to a stop. If you're car is automatic I would not suggest doing neutral drops.. you'll cause more damage.
