My car does not have cruise control. That's what is confusing me. I cleared the code earlier and will drive it tomorrow to see if the code returns.

Have you noticed any erratic behavior in the transmission when driving? Hard shifts? Slow shifts? Revs hanging or climbing before shifting into the next gear?


Edit: Also, at the very least, check ALL accessible fuses.

I have no idea. I do not know those codes, nor did I look up those codes.

Cheese and rice. Please do not look at OR consider any (scan tool) bank2 data or codes. The bank2 stuff is for other cars OR other engine types. Our Focus has only bank1.

Fuses? -no
Trans? -no
Other ideas? -yes.

I will guess your car has 12-hole RED colored (Bosch) fuel injectors? YES or NO?

That symptom sounds exactly like what I had. But maybe only if you have RED colored fuel injectors. It "drove" me crazy trying to figure out that exact problem & symptom. Those buggers (red injectors) do that... <<plus other symptoms too >>.

"foot barely on the gas pedal at a steady speed (usually 50-55mph), I feel an occasional "jerk"

I will guess your DTC (code/s) is another issue & completely separate from the "jerk" at 50-55 cruising speed issue.

Gd Luck

May not be your problem but my 2002 SOHC used to "buck"
very random and not very often but it ended up being my coil.
Didn't get any codes for a long time. finally got a misfire code.
Just my experience.
