Hi scotty i have 2013 ecoboost f150, bad idle, already clean throttle body, checked for vaccum leaks, battery is ok 80% , used seafoam valve cleaning for carbon build up, changed map sensors and cleaned intake air sensor, did a throttle body relearn idle, still has rough idle, should i remove intake monifold and clean the valves by hand? What do you think ? Watch you every day, thank you
Adding to that, i gapped a colder spark plugs to .28 didint work and now did oem plugs gapped on .32 did not work eather, coils are all new also , can the throttle body be damaged maybe even with no check engine light? Will be checking if its that bad on carbon build up, Thank you all
Clean the IAC valve.
Hi thank you , but it doesn’t have a iac valve
Did you use the OEM sensor for MAP sensor?
Check the IAC and TPS. Clean both the MAF and MAP sensors.
Hi thank you ,but it doesn’t have a iac valve or tps , its all comuputer controlled
Do you have any carbon buildup?
Hey i do not have carbon build up, just removed the intake manifold to clean, its clean, i got a catch can it helps, so now i got no clue what it is.
@brunolima crazy, I mean the ecoboosts are not the greatest motors to begin with and overly complicated. Hopefully you’re able to figure it out.
