Move the coils and see if the misfire moves. If it does, then you know you have one bad coil to replace. If the misfire doesn't move, pull the spark plug after the engine has cooled back down overnight.Well my BlueDriver came and I must say it was the easiest thing to hook up to the LeSabre. Here are some screenshots of the reports he gave and it looks like it so it’s showing a misfire on cylinder two. Sometimes the check engine light stays solid but I took it for a short neighbourhood drive today and it started flashing again and I still have a subtle but consistent hesitation when I first hit the Excelerator and then the engine appears to drive normally. Here are some screenshots of the OBD scan findings. The original owner replaced the coils on the car sometime ago but I have no idea what the quality or brand wise. If I end up replacing a coil, should I replace all three or just the one for cylinder two? Also, I priced the ignition coils for this car on Amazon and I can get either a Delphi brand or an AC Delco professional/gold brand. The AC Delco is actually more expensive but it looks like the Delphi is still US made. Or does any of my hair splitting make a difference really?
Most likely not.Wondering if there are coils made for this engine anywhere in North America?
