Erratic idle after EGR delete/Oil Cooler

[King130]

I just replace my oil cooler and did the egr delete kit by sinister. I have a 2006 ford f250 king ranch. After the install i started the truck up and it idles fine for 5-10 seconds and then starts a very erratic idle. We left the truck idle for a little bit to see if it cleared up and it did not. As a just cause we disconnected the MAF and the truck idle smoothed out and ran fine. Any help would be awesome!

how does it drive? any codes?

Regardless of your egr being deleted i would make sure the valve is clean it can still cause flow problems... And when you did the oil cooler did you make sure to be very clean about it? any debris could and would clog up your ipr... let us know... make sure your map sensor is plugged in

Yes, an IPR screen plugged with lint from rags is a very common problem to have after an oil cooler replacement. Your statement about the MAF was a little odd, but I would still check the IPR screen any way. BTW: If your EGR cooler was deleted then It doesn’t matter what the condition of your EGR valve is or if you even have one for that matter.

just leave it in removing the egr valve can cause some problem with the cooling fan not kicking on under heavy load..... Especially if a tune is overwriting the existince of it....

When I drive it it is very jumpy. I have not driven it with the MAF unplugged though. When I did the oil cooler I was very clean about doing it. I cleaned the oil cooler valley with a bunch of carb and choke cleaner and then ran a shop vac down there just to make sure there was no debris. I deleted the EGR valve and installed the cover plate. The MAP is plugged in, I just don't understand why it runs smoothly when the MAF is unplugged.

thats just coincidence,imo,,just a map issue,nothing to do with the egr delete.

check your injector connectors which can get damaged reinstalling the intake and check the ficm connectors on the ficm which can be hard to get seated.

after those things are fine I'd be pulling out the IPR valve, there may just be enough **** on the screen to cause a problem

I just started he truck again and downloaded codes and got a p2284 which is injector control pressure sensor circuit range/performance. I am new to working on diesels so any help would be greatly appreciated.

try unplugging the icp and see if she smooths out. it is on the pass. side valve cover,and screws thru it into the hp oil manifold.
