Check Engine light constantly on - had it checked 3 times and told it was lean gasoline - then the actuator arms fell off on intake manifold runner control when the mechanic tried to put in new bushings and he also told me that its leaking oil - the engine is listed at lean at 1 and 2 on the engine.
I have only had this vehicle for a couple of weeks so I do not know for how long the P0171 and P0174 code have been on. I erased all the codes when I bought it and they came back up. This is another item that ford should recall and have fixed. They should at a minimum pay for the labor. These codes are caused by a design flaw in the valve cover that allows oil to get to the isolator bolts and cause the rubber material around the bolts to shrink and crack creating a vacuum leak between the upper and lower intake manifolds due to a loss of tension. This is a very common issue in these vehicles and Ford does have a TSB out for this problem. It is so common that you can buy a kit with all the parts needed specifically for this problem. I will be buying the kit to repair myself but I will still end up having to take it to the dealer to pay for the PCM to be reprogrammed which is another requirement under the TSB and unfortunately I can not do it myself. What a bunch of BS.
I have been dealing with this problem ever since I bought this junk. I have replaced the MAF sensor put in new fuel filters also the number 5 valve has been going out since 2006 now the number four has joined in. I have asked numerous people how to fix this problem but am told that it is in the winstars nature.Will isn't that great
Having check engine light ON in the car. It cannot be inspected in NY. So first I replaced the Carb. in-take gaskets, it worked a little bit, but it came back on. Now I can either change the O2 senor in the one bank (exhaust) or do the in-take again. HELP ME!?!
