Bad running

Postby I.mcguinness68 » Tue Sep 21, 2021 9:09 pm

Hi . Need some help . Transit 2.4 rwd .59 plate 115
Starts up from cold smoke is white/gray. Code read now says clear.
I've changed fuel filter. Injectors and had them retested today. Done prv and scv today. Cleaned egr valve. Checked all fuses and going to give up
It miss fires between 1000 -1500 rpm and smokes clear on tick over after its warmed up but still smokes at 1000 -1500 cold warm or at temp

What code reader was used..??

Were the SCV & PRV genuine Ford/Denso items..?? Were the learns done after fitting the valves.??

The learns need to be "completed successfully" or it will never run properly. Be sure to reset the PRV open/duration timers.

I did egr valve today and it's like a different van but still smoke on start from cold. I know it's injector.
Would it do that if a number was out on programming them in .
All injectors have been re tested and come back good. Scratching my head lol

If the injectors were the originals, did they go back in the same cylinders they came from..?? Best to check the correction factor numbers vs the PCM information. Have the pump, pilot & injector learns been completed successfully..?? If not, you're wasting your time.

Would a incorrect injector code or a failed learn make it smoke it's tits off and miss fire?
After egr replace all the smell has gone when driving and pre inginition knock gone so obviously that was an issue but I think I've causeda problem trying to fix the original issue

Am assuming you don't feel the misfire when driving (most have this what feels like misfire when stationary at around 1300rpm)
Do as his lordship said, code injectors, do the learns , reset the counters etc makes big difference

So recoded injectors did pump learn and cleared counters. Injector learn keeps saying please wait. Counts up to 3min 20 second then starts again how long do these take because it was getting to late so I cancelled it

lf your battery isn't fully charged or not well, it can cause issues.

If it fails the pilot and injector learns you may still have a poorly injector....I know you've had reconditioned ones but there may be a duff one.
