I know this is a common subject here but I need a little help. My 01 ST, when it is cold out side it will not idle at first. I have to keep it idling myself. My cel is saying both banks are lean. I had my idle control valve cleaned and I changed the fuel filter and it still does the same. My question is should I change the idle control valve or the o-rings next. I was told that even after I clean it that could still be the problem. I wonder this because after about 45 seconds it idles fine. I was thinking that if it was the o-rings it would do it all of the time.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
Thanks for any help.<o></o>

you might check the small vacuum hoses above the left valve cover also. a loose hose or cracked hose can give the code. pull the hoses off and check condition. your right, both codes (both sides) means problem is common to both.

 

Is it the sohc? If so I'll bet it's your lower intake o-rings. When it's cold you get a small vacuum leak which kicks on the CEL. Once it warms up the leak seals itself and the idle smooths out. There was a recall for this as well as the upper cam chain tensioner and oil restrictor to eliminate the front cam chain rattle. Ford has a kit that includes the upper and lower updated o-rings along with a new tensioner, oil restrictor and oil passage pipe plug. I just did this on my 2000 explorer. Ask for kit tsb-00M12.

 

would this be covered under any recall. i have heard that there is a recall on this but i can not find it any where. i even called my local dealer and asked them and they acted like they did not want to talk about it.

 

It would appear that the FSA has expired.

AFFECTED VEHICLES

SERVICE ACTION


Owners of affected vehicles are being notified that Ford Motor Company is providing additional coverage for the affected engine camshaft chain tensioner and lower intake manifold gaskets.
If either the camshaft chain tensioner or lower intake manifold gasket should require replacement, dealers are instructed to install both of these upgraded parts at the same time, at no charge to the customer.
The no charge coverage for this condition is available for 6 years or 72,000 miles from the vehicle's warranty start date, whichever occurs first, and will automatically transfer to subsequent owners. If the vehicle already has more than 72,000 miles, this coverage will last until April 30, 2001.
Please read Attachment IV (Question & Answer Sheet) for more details.
REASONS FOR THIS PROGRAM

We have incorporated enhancements into newly produced Explorer 4.0L SOHC engines. The long-term benefits of these improvements are being offered to prior customers.

The need to install a replacement camshaft chain tensioner is typically indicated by an engine rattling noise that occurs just after cold engine start up and goes away within a few minutes after the engine is running. Rough idle and low idle are symptoms which may, in some cases, indicate an intake manifold leak.

The condition of either or both of these components will not cause engine damage or failure, but may decrease the customer's satisfaction with their vehicle.

 

FYI, these are the FSA's out for the '01 Sport Trac, 05S28 being especially important to prevent a FIRE
