I can rev the engine to 4k, smooth as silk. I want to know why it is jerking for 2- 4 time in a day while at start, during accelerating and during constant speed. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. The engine light is on and the code I receive explains that the engine is running a lean mixture. I can rev the engine to 4k, smooth as silk. Stalling means it need the new front valve cover kit. When removing the air scoop I didn't see any problem with the gasket itself nor did I see where it was allowing any bypass of debris from outside the engine.
Thus, the engine will sputter and stall slowly. Dear Olopezm, Thanks for kind advice. But once driving it, when stopped at a stop light or whatever, the ldle lurches up and down. If you need the Shade-Tree Mechanic's instructions they are easy and really do work let me know. Best wishes, AzharJ In that case I think it would be a good idea to: Replace plug wires Check spark plugs for correct gap Test.
I took it for a 15 minute drive, trying to see if I could get any error codes, but no such luck. Not looking forward to this one. The error code I get is P0171 and P0174 System too lean bank 1 or 2. Might want to read some of the google search here. I believe this means a general misfire? If it's been a long time it would be a good idea to get a new set of wires.
Yesterday stalled at red light. Checked out a repair manual at the library for additional help and a little peace of mind. Dear Olopezm, Now the problem is over. A vacuum leak from a hose by plug 6 I believe, that kept coming loose caused some of the stalling problems but not all of them. They did the repair correctly and after 2,000 miles everything is running good. I have yet to check the vacuum lines, as the posts above tell me to do, but could it be that simple? I checked the local auto parts stores and they all carry a kit Valve cover, gaskets, bolts, pcv, fuel pressure sensor, etc.
I had a Ford dealer look at it and they said everything with the engine is fine. If not… it will stall if the fuel injectors haven't been cleaned for 30k miles and if it has been over 30k miles since the base idle and engine timing have been reset. We thought cooler temps and then warmer temps and even moist days, but there is no real pattern. I do have one last question though if anyone can point me in the right direction. Do you feel your windstar shaking when you stop at a street light?. Hope the weather warms up now. While it seems to run better now while driving down the road, it still is randomly sputtering and almost stalling out while at idle sitting in park.
I found the filter cartridge below the pcv valve had carboned up, and after the crank case pressurized, oil was forced out the pcv supply line to the throttle body. Sounds like at idle you are not getting the proper air or fuel or both. That was definitely the problem. I thoroughly cleaned them and cleaned and degreased the gasket surfaces and channels. Ok as a final follow up to this nightmare, I have the van running perfectly now. Sealed the bolts holding the plastic intake to the aluminum intake.
Sealed the top plastic intake to the bottom plastic. If you remove that line and see any fuel coming out of it, that's your problem and need to replace the regulator. What could I look for before I wait for the check engine light to turn on? Took back again to mechanic to check out. Installing a new thermostat while you were right there was a very good idea. I have a 2000 Windstar with 71,000 miles on it. Any help or ideas would be greatly appreciated! I have a 2003 Ford Windstar, same problem,Ford is covering up the problem.
It may give you clues as to what may be causing the stalling, low idle, or rough idle. That could also indicate bad spark plugs and spark plug wires; if those have not been serviced in a long time it would be a good idea to replace them. I have changed all parts including… An engine is just like a human in many ways. Best regards AzharJ You're very welcome my friend! It would be easier if you have access to a live data capable scanner. I guess I was hoping it was water in the filter, or that it was plugged. Any reading of over half a volt indicates resistance eg.
This is what led to the difficulties I am having now. There are potentially other symptoms as well. Check the fuel filter… This is me, answering my own question. Added injector cleaner and Heet and seemed ok. Now turn the key on engine off. Never had problems like this with my other Windstar, but can't remember what year it was.
