1LivingontheEdge Posted September 16, 2019 Report Share Posted September 16, 2019 (edited) Hello everybody! New member with an issue. My Edge has a little over 201k and starting Monday of last week came down with a strange problem. I had been off from work running errands and had stopped at a local Kroger to pick up a couple items before heading home. Car had been running fine and ran fine when shut off in the parking lot. Was in the store about 15-20 mins, came out and started the car and it was running rough with a flashing check engine light. Managed to limp it to hubby's work (local airport) and his mechanic came out with his (professional) computer and cleared the codes (P0303 and P0203). When started again, it ran fine all the way home. After getting home and shutting it off and waiting 10 mins or so, restarted the vehicle and the rough idle and codes were back again. This is where it gets strange. Let it sit long enough to cool down and it runs JUST FINE. No issues. No power reduction, no codes, no rough idle...NOTHING. It runs perfect. It has consistently followed this pattern of rough idle on restart after being driven. The only thing to change is the fact that only the P0203 code comes back (misfire code has not come back) and a P0171 (lean code) has popped up, but has not been back since Thursday of last week. Hubby took negative cable off the battery to reset the computer and noted that it arced bad when being put back on, which it should not do. I am wondering if anybody else has had this issue and, if you did, what did you do to fix it? The earliest the local dealership can get me in is on October 4th. I am not dumb when it comes to things automotive (have good basic understanding and can do a lot of my own basic maintenance), but it seems if something was indeed wrong with the injector that it would act up all the time, not just under certain conditions (but, again, I could be wrong!). I am not sure what is going on, but this is something I have not experienced before. Any input is appreciated. Thank you in advance! EDIT: I should mention that I bought this car used with 172k and have no idea when/if the spark plugs/coils etc have been changed.

WWWPerfA_ZN0W Posted September 19, 2019 Report Share Posted September 19, 2019 Cylinder 3 does seem to be problematic, and points to the origin possibly being due to an injector issue. I would replace all of them, budget permitting. Since the intake has to be taken off anyway, good time to check all the plugs and coils, to make sure to not caught in the plug/coil/PCM vicious cycle. If only the plugs look worn out, replace them all. If ANY of the coils look cracked, burnt or carboned, ALL of them need to be serviced simultaneously to fix this for the longterm. circuitboardmedics.com can fix the PCM for far less than a new one would cost. Ford has a kit they issued for the plug/coil issue. Do not ask dealers about it. Buy online direct from the dealer. About 180 or less shipped for plugs/coils/gaskets.

1LivingontheEdge Posted September 19, 2019 Author Report Share Posted September 19, 2019 When you talk about this kit and buy online from the dealer, can you show an example? The more I read, the more it points to the injector. It's odd that I only get a code when it's hot, never when cold. I want to do this right the first time and for the long term. I'm used to stuff I can work on...not all this electronic stuff. At 201k, a tune up is likely due. I'm not sure what has/has not been done as it was used when I got it. I like the car, though. Thanks for the reply! ? Quote Link to comment Share on other sites More sharing options...
ih772 Posted November 6, 2021 Report Share Posted November 6, 2021 OP, I'm having the same issue. Did you ever find a solution? Quote Link to comment Share on other sites More sharing options...
1LivingontheEdge Posted November 6, 2021 Author Report Share Posted November 6, 2021 It turned out it was the injector on cylinder 3. Replaced it and the issue went away. Happy until the transmission went out at about 215k. Put another transmission in it thinking with the price of new cars and the relative limited selection I was doing the right thing. The second transmission started coming out with just over 5k on it, so I ended up trading it in and buying a new Sorento. I miss my Edge. I didn't want to get rid of it because I loved it, but it was either pricey repair bills or a car payment. Car payment was cheaper. 1 Quote Link to comment Share on other sites More sharing options...
