98 ranger bucks and sputters when cold at higher rpms
My 98 ranger 3.0 5 spd jerks/ bucks/ sputters feels like a hard misfire at higher rpms when cold. After it warms up, you can't make it do again. Happens when you push past 2700rpms before shifting. I just did all the plugs and they are spotless. I did get codes for the egr system.
P1451 evaporated control system canister vent solenoid circuit malfunction
P0401 egr flow insufficient
p1400 dpf egr sensor circuit low voltage detected
I have replaced these...
EGR pressure sensor
Seafoamed the motor
It runs great and idles good just scares me with this issue.
Any help would be greatly appreciated.
