11Lemon Posted November 8, 2020 Share Posted November 8, 2020 Car has been blowing spark plugs. Changed the injector out, coils and plugs. Twice my check engine light has came on saying misfire cylinder 1. Check it and the spark plug is crap and burnt. New spark plug in, drives great for a month then boom. Jerking and stalling out. No leaks. Wtf is going on?? 0 Quote Link to comment Share on other sites More sharing options...
akirby Posted November 8, 2020 Share Posted November 8, 2020 It’s possible the cops messed up the PCM and it’s overdriving the new cops. Do a search - lots of info. 0 Quote Link to comment Share on other sites More sharing options...
eGuru Posted November 8, 2020 Share Posted November 8, 2020 Please post a picture of a "blown" plug. That could help us narrow down the cause. Which engine do you have? mileage? 0 Quote Link to comment Share on other sites More sharing options...
11Lemon Posted November 8, 2020 Author Share Posted November 8, 2020 It's the 3.0 V6 automatic with manual option. I'm no mechanic lol. Mileage is 126k. This plug was out of cylinder 1. Only was in it for a month or so. This time around my check engine light is flashing but won't go solid yet to read the codes. Mainly starts jerking and trying to die after its warmed up. Same exact thing It did the other 2 times. 0 Quote Link to comment Share on other sites More sharing options...
eGuru Posted November 8, 2020 Share Posted November 8, 2020 Have you been monitoring your oil usage and coolant levels? 0 Quote Link to comment Share on other sites More sharing options...
11Lemon Posted November 8, 2020 Author Share Posted November 8, 2020 Yes. It uses hardly any oil or coolant as it should. Had an oil change about a month ago also. Also new fuel filter. 0 Quote Link to comment Share on other sites More sharing options...
bbf2530 Posted November 8, 2020 Share Posted November 8, 2020 (edited) Hi 11. In addition to the good assistance of eGuru and akirby: If your Check Engine light is flashing, that means you should not be driving the car. Driving it can damage the engine and/or catalytic converters. This could be anything from the the injectors or coils to a damaged PCM. Also, I am not sure why you think the CEL has to be solid to retrieve codes. How are you trying to retrieve them? Also, just as an FYI: that is not a "blown plug". It is an extremely fouled plug. Whether it first occurred due to a damaged coil or the PCM going bad is more of a "chicken or the egg" kind of question at this point. However, among the possibilities, a defective PCM will lead to your symptoms. Since you already replaced the plugs, injectors and coils, the PCM may be your culprit, as akirby mentioned. And I believe a troubleshooting tree would point you there next. I am sure eGuru and akirby will jump in with more assistance. Keep us updated and good luck.

11Lemon Posted November 8, 2020 Author Share Posted November 8, 2020 Again I am no mechanic so blown or "fouled" out mean the same to me lol. I'm not driving it atm because of this issue. Orilies is the closest to my house to check the CEL but without it being on they come up with nothing. There isnt a ford dealership or mechanic shop around here. Closest one is over 30 miles away and it dont make it that far. Wouldnt my check engine light if and when it does decide to illuminate tell me that the PCM is going bad? Or is that a sign it is in fact going bad? It's an expensive part to not be 100% sure that's what it is. 0 Quote Link to comment Share on other sites More sharing options...

I assume you meant O'Reilly Auto Parts? Just like AutoZone and other big box auto stores, they have the capability to read some codes, but not all. Even with a code, we could not tell you exactly what the problem is. Codes usually do not say "The problem is X, replace it...". Codes point to a list of possible causes, and hopefully a troubleshooting tree or an idea of where to start. And codes are usually stored in the vehicle memory. So a shop/tech with the proper tools would normally be able to retrieve stored codes that a big box auto store may not be able to. Unfortunately, this issue can not be diagnosed over the Internet. Therefore, without a code, we are even blinder than with one. However, throwing parts at the problem is not a good idea. As you can see, you spent money and replaced many parts that were not the root of the problem. If you want to do anything other than guess and throw money/parts at the problem, you need a shop/tech or Ford Dealer to retrieve your codes. If another member has any good ideas for another way to do this, I am sure they will jump in to help. Keep us updated and good luck. Edited November 9, 2020 by bbf2530 To correct typos.

eGuru Posted November 9, 2020 Share Posted November 9, 2020 I with @akirby and @bbf2530 that you need to pull the codes that are causing your CEL before replacing any more parts. The fouled plug points to a mechanical issue and not electrical but either way, you need to qualified mechanic with the proper diagnostic equipment to analyze the cause. 0 Quote Link to comment Share on other sites More sharing options...
bbf2530 Posted November 9, 2020 Share Posted November 9, 2020 Hi 11. eGuru's reply about it more likely being a mechanical as opposed to electrical issue brought another question to mind: Out of curiosity, did you pull/inspect any other spark plugs to see if this was limited to cylinder #1 or a more widespread issue? Keep us updated and good luck. 0 Quote Link to comment Share on other sites More sharing options...
Fusion Fan 200 Posted August 7, 2021 Share Posted August 7, 2021 (edited) Try using forscan at www.forscan,org It has good diagnostics to read dtc's that the regular scanners cant pick up you can also test different modules . You will also need a elm 327 obd11 connector with medium speed and high speed switch you can buy at Amazon to use on a laptop the usb ones work the best in my option. I use it on my 2014 and friends coworkers fords Lincoln and mercury automobiles and they love it.. forscan also has a forum .. You can turn off seat belt reminders day time running lamps on certain vehicles Depends on the vehicle u can turn certain things on and off .. Make sure you do your research before attempting to change anything .. Edited August 7, 2021 by Fusion Fan 200 0 Quote Link to comment Share on other sites More sharing options...
