Almost had the van sold today but apparently the misfire was one bridge too many. No CEL but guy hooked up a $30k SnapOn reader and discovered it’s 7 and 9, which are both on the right bank.
My guess is that it’s 2x $10 ignition coils, maybe plugs and wires too but I’m too burned out on this car to want to do ANY more than the bare minimum to make it leave (I’m losing $1200 on the sale so far, want to stop the bleeding)
thoughts? ‘03 Super Duty V10 Ford E350. 195k miles
When I worked in a shop we had a couple of these that constantly came in for ignition coils. Apparently the stockers are bad for failing. One of the owners noticed that a full set of Accel coils was the price of two stock coils. He went with them and he never came back for those coils again.
Convinced the other guys to try em as well and they also never came back for the coils. All were very happy.
Did they have coil-on-plug on the V10s? If so, throw some new coils at it. I've used Accel and Denso coils on my Town Car and they both seem fine.
It could just be the rubber boots are worn out but the whole coils aren't too expensive.
In reply to P3PPY :
I agree, I'd either throw two new coils on it, or I'd swap a couple around & see if the codes follow the coils.
Also, having a 4.6 in mine I have no clue how Ford stuffed a V10 into one.
Oh nice, good (money saving) thought on moving them around. I'll try that first and then the Accels
From the small amount of time I worked in a shop and sold parts (~2 years or so), I saw a ton of Ford modular engines get new COPs. It's very common. Even the Dorman rep said that the factory coils fail at a pretty high rate.
The V8s and V10s in the trucks and vans seem to eat them more than the cars do. I think the heat kills them.
Hopefully it's a simple fix!
They're also not very securely mounted, i think they endure a fair bit of vibration.
