2001 Ford F150 shaking problem
I've got a 2001 F150 4.6L V8 that I recently bought and Ive been having some problems with that I can not figure out.The truck begins shaking when I get around 30-35 then goes away until I get around 40-45 then goes away thereafter. It also feels like it misfires at times. I had originally gotten some codes for o2 sensor going bad and an insufficient egr flow and a misfire on ignition coil 5. I replaced the o2 sensor...removed and cleaned out the whole egr ports and throttle body and replaced the dpfe sensor. I replaced the ignition coil on 5. As well I have cleaned out the air mass flow sensor. Any ideas on what it could be? Please let me know.

I just scanned it again and no codes came up. I've driven it about 50 miles since the last time I reset the battery. The codes that I had before were
P0401- Powertrain "Exhaust Gas Recirculation Flow Insufficient Detected"
I replaced DPFE sensor and cleaned out the EGR ports which were clogged with buildup
P0136 - Powertrain "O2 Sensor Circuit Malfunction (Bank 1 Sensor 2)
P0141 - Powertrain "O2 Sensor Heater Circuit (Bank 1 Sensor 2)
I replaced the O2 Sensor on Bank 1 Sensor 2
P0355 - Ignition Coil E Primary/Secondary Circuit Malfunction
I replaced that part
Since its not showing any codes I can't find out why it has that shaking problem and the misfiring. Sparkplugs were all recently changed out within the last 6 months.

Ok...I've been driving the truck for awhile now , maybe 60-70 miles, and the MIL has not come back on. When I would clear the codes back then they would come back on within 20-30 miles of driving so I'm guessing they are not going to come back on. The only thing I can think of doing now is replacing all the ignition coils.
I found these on ebay can anyone tell me if these would work or would be better off buying the ones from an autoparts store where I would pay around $50 dollars each ignition coil.

Also I found this thread on a different forum where the guy had problems with his truck shuddering under load and he ran a half pint of seafoam in his engine oil for about 50 miles and than I changed the oil and apparently it fixed his problem. I'll get back to you guys to let you know if the seafoam helped.
But if anyone could please let me know if those ebay ignition coils would work out.

If the misfire isn't severe enough, the PCM won't set a MIL or a fault code (misfire rate is below the calibrated threshold required by emissions standards).
You can use a scan tool to look at the Mode 6 data (as I already advised) and see the individual misfire counts instead of blindly replacing parts.
