How long have you let the truck run since getting it back together? It can take a good bit of running to get all of the air out of the system. I have seen it take almost 500 miles after having the system dry to get the air out. Does it run fine other than the idle?Just did oil cooler egr delete. Truck seems to be surging, rough idling. What should I check? The maf is showing nothing on forscan software. Could that be something to do with it?
Thats my guess is you just need to give it enough time to make sure all the air is out of the HPO system. Like I said it can take way longer than you think. As for the MAF and Forscan, someone more fluent with Forscan will have to answer that because I am not sure.Its actually idling way better after running it for a while. still no maf reading. Is that an issue?
