He said maybe one of the wires in the harness got snapped or broke off when the first mechanic was removing the coil packs. This was the root of the problems. However, from my description the mechanic felt it was probably a leaking fuel injector,which is what I was originally thinking. Ran a compression check, looked for vacuum leaks, everything checked out. I can hear the hissing noise in there, and have been spraying carb cleaner to try and find it, with little change in the idle.
I'm no mechanic, but two have failed to find and fix the issue and I'm hoping someone on this forum will know what's going on and be able to point me in the right direction. I'd rule out everything before doing this though. Elite Explorer members see practically no ads, can add their own profile photo, upload photo attachments in all forums, and Media Gallery, create more private Conversations, and more. It has never been in the shop for anything besides oil change etc. Also, forgot to mention when I got the car 10k miles ago it now has close to 170k , I had the following done: - Replaced fuel filter - Power steering flush - Serpentine belt replaced - Transmission fluid serviced I replaced the spark plugs myself, which is how I found out about the oil in the coil boots. Unlike the cheaper Haynes and Chilton manuals that cover multiple year models, leaving the exact information you need to fix your car, these professional manuals cover your exact year, make, model. Below is a link to the part.
The true test is seeing if it stutters after its next fill up. Again, I would never have thought that by trying to fix that problem, my car would run as terrible as it does now. The cost is about nothing if you have a piece of scrap laying around. You know the sound you make when you chase your kids around pretending you're going to eat them? My assumption is that because the engine is running like crap, the alternator is not generating electricity quick enough to meet the demand. The mechanic said he didn't test drive it when I dropped it off and it must have ran like that before, and he essentially refused to try and fix it. If no response is observed, the O2 sensor should be replaced. In the interim, time to change the oil as it reeked of gas.
At any rate, let me get into what's been done and what I know, based on another mechanic I took it to. By continuing to browse our site you agree to our use of data and cookies. The most common is a vacuum leak in the intake manifold on bank 2, in the case of this code. Few reimburse incidental costs like motel rooms if you have to wait for repairs. A lean air fuel mixture can burn valves, cause overheating, damage cylinder walls and or pistons as well as blow head gaskets. Car stutters frequently and sporadically some days are good. I've even waited 10 mins after a fill up before starting to see if sediments were getting tossed around and it still happens.
Mit anderen Worten, das Auto ist reif für den Schrottplatz. Again, the first mechanic was supposed to have installed new gaskets and I do indeed have the old gaskets in a box - I asked him to keep all the old stuff so I could be sure the job was done. The more you press at the same time, the less electricity I guess the car has. We only pump on the slowest setting and we do not top it off, ever. When it is determined the O2 is actually good, diagnosing the actual problem can be challenging.
The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The vehicle also stalls hard right after a fill up. After some troubleshooting they narrowed it down to the the Vapor Canister Purge Valve. I personally have not seen the misfire code, the only reason I'm believing it's misfiring is because removing the coil-on-plug on that single cylinder doesn't affect the engine's idle. However, also includes disassembly instructions for interior trim panels and exterior items like headlights and tail lights. No check engine lights, no rough starting or idling. Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components.
It's a good idea to inspect the entire set of lines that for cracks and melted fittings. After that repair mechanic handed over me the vehicle with engine check indications. Of course you may have to take that with a grain of salt because to my untrained ear, it could be nothing. One of them was dark black and looked wet. If there are no obvious signs of a vacuum leak, the mechanic should suspect a faulty O2 sensor. The sensor element is made of platinum coated zirconia and includes an inte- grated heating element.
The Expedition's Error Codes Easy to see and nice to have a print out of the codes. For some Ford products it is for a lean O2 sensor. When sucking, if I plug the top nipple, it sounds like I'm getting air from the top of the solenoid. The heated oxygen sensor has the characteristic whereby its output voltage changes suddenly in the vicinity of the stoichiometric air-fuel ratio. So at this point, the second mechanic told me he's stumped and without all the parts and tools and computers that a Ford Dealership service center would have, he can't really make any more progress. This can damage the catalytic converter and in some cases, start the catalytic converter on fire. Edit2: Found another post about this possibility.
If you need a low cost Engine Scanner and have a Cell Phone Andrioid or Apple take a look at some of the low cost options that use wireless and your phone to scan and reset codes. Two screws and one connector, right under the engine shrowd towards the back of the engine. Explorer Forum has probably saved you that much already, and will continue to save you money as you learn how to diagnose fix problems yourself and learn which modifications work without having to experiment on your own. The test fails when the fuel control system no longer detects switching for a calibrated amount of time. I left the sensor unplugged, then unplugged the battery for 10 minutes, plugged the battery back up, started the car up again with the o2 sensor still disconnected - no change in idle at all. But other components can create conditions to set this code.
