Runs rough at idle update.
Sorry couldn't find my other post so Il just start over again. New injector cups injector o-rings, 2 new injectors, new valve cover gaskets,ipr,cps, icp, and now a new rebuilt idm. Just a little bit of change runs better once again like after I have done all these things but it still isn't right. I have ohmed out all wire from idm to injectors and all is good there so I know the wiring is good.
Here is a couple weird things that happend recently. With edge chip unplugged P1316 would go away. Put a tune on it and it comes on. Wasn't doing this before.Now after a while of driving it stock the P1316 will come on but takes a while. I put new idm in and soon as I rev it up a little it comes on right away with no tune installed.. So I put the old back in and cleared codes and P1316 doesn't come on after I rev it up. Put new one in and right away its back. Do I need to have the code cleared by ford to see if it stays away. Is it just engrained into the memory.
Next thing I was thinking about was could someone have left a tune on the truck before I got it so when I put the edge chip in it it completely is just messing things up. I am at a loss and looking for anywhere or anything to try next.
Everything has been replaced due to codes that have been pulled. I have not just been throwing this part in and that part in. Last time at ford got told wiring or under valve cover gaskets must be bad even after I told them there new and I ohmed out the wires so Im done with them.
