In conjunction with the AIH Delete Plug??
1999 F250 7.3 .. The truck seems to idle fine and and runs smooth all the way up top cruising speed, but when it levels out at say 65mph then it starts missing and jumping. I can ease into the throttle a little and it smooths out up until it levels out again.
I have the Vgate Elm and Car Guage Pro and a couple of other apps and the only DTCs I'm getting anymore are:
P0541 Intake Air Heater Circuit Low
P0640 Intake Air Heater Control Circuit
But from what I've read, neither of those should cause this issue.
Buzz test sounds good.
Cylinder Contribution test throws code for #4 Cylinder
I'm trying to do everything possible before throwing an injector in it.
Doing oil cooler. Block heater plug is very tight. Is it reversed threaten?
View 1 RepliesI have an emissions test coming up. I have 3 P codes that I'd like to eliminate before then. I don't want to "fix" the issues they are telling me about. Just make the codes go away. I know why they're there I just need to get rid of them.
What I have coming up is:
P0475 Exhaust Pressure Circuit Valve (result of EBPV delete)
P0541 Intake air heater A circuit low (result of aih delete)
P0640 Intake air heater control circuit (also result of aih delete)
What resistors I'll need and where to put them in?
Early 99' model I picked up. Blew the oil cooler and had lot of pressure in the Degas bottle, so did head job and oil cooler and now I'm Still getting a P0264. Unplug #8 injector truck almost dies, plug it up and she smooths out...
View 7 RepliesHow to fix SES P0670?? I understand there's a whole procedure on checking fault.
P0670:GPCM Glow plug control module control line failure. Open/grounded circuit, open/shorted GPCM, failed PCM
But how did you resolve problem? replaced GPCM, found open circuit, short --if so where?-- or replaced with updated harness.
(4C3Z-12B568-AA connector upgrade kit as in picture)???
What does it mean when you find oil in in the cold air intake, is this normal?
View 14 RepliesWhile doing a visual inspection I noticed that the AIH hot wire (captured nut wire) had broken off and was laying loose. I removed the wire from the relay and made a new 8 gauge wire, I connected it to the relay and was about to add it to the AIH when I got a healthy spark ( it touched the ground wire ) and yes the truck was not running and the key was out at the time.
This sounds to me like the relay has gone south, am I right??? I have a new OEM relay to install but I have a question. In what order are the wires and ceramic fitting go on the AIH post???
Noticed a while back that the plug for what I assume is the air intake temp sensor is looped. I assume because I can't find the sensor anywhere. how critical is the sensor? The new S&B has a hole for it so it's either gonna need a new sensor or a plug. The local autozone has one for 16.99.
View 12 RepliesDumb question but how do I remove the air filter intake from the turbo Its a little oily there from a fuel or oil leak but I dont see a clamp holding it on the turbo?
Also what is the e clip? Is it the little thing holding the wastegate rod on the exhaust turbine? Can I just pull the rod up off the clip?
I own a 2003 E450 (transit bus conversion) with a 7.3L w/ California emissions. I recently noticed I have a considerable amount of oil in my air intake going back all the way to my turbo starting where the crankcase breather tube attached to the air tube. The breather seems to have some sort of filter housing that is attached to the top of the valve cover. I removed it and it appears to be fairly heavy as in if it's a filter, perhaps it's full. If I'm getting oil into my air intake from where the breather tube comes off that housing and joins in my air tube back to the turbo, could that filter or housing have gone bad? It appears to be a dealer stock item only for 225. I've saw on the web people posting "reroute kits" for the 6.0L but nothing for the 7.3. Does this part simply need replaced or could I be facing a separate issue as to why I'm getting oil in my air tube?
View 14 RepliesI have an 04 excursion with a stiction problem. I can't afford New injectors so I'm going to try this. My question is it says use 2quarts with a fresh oilchange. Do I use 2less quarts of oil than usual or do I add the 2quarts to a normal amount of oil?
View 5 RepliesPut in my new S&B intake today and when I stomp on the gas I am getting a loud shuddering noise from the intake when I change gears. Also sounds like a squealing sound sometimes. Doesn't sound like other trucks that I have heard. What that could be?
View 14 Replies2002 7.3L SD ... He told me when he was taking his son to school he turned on the heater. When he did this he could feel the truck lose power, he turned the heater off and it drove fine. Turned it back on and power loss happened again. I haven't driven it to test yet or see what is happening but I also don't understand how this can happen. The heater did get warm, and he does not have to add coolant to the system.
View 13 RepliesOn the back of my truck I have two plugs to operate trailer lights/brakes etc but I only use one. The one I'm not using (pictured) I'd like to adapt for aux power in the trailer to operate some IP cameras. I need to know about the pin outs of this connector and what gauge wire to use between the trailer and truck. I plan on running the 12V and ground conductors from this plug through an adapter into the trailer.
In the trailer I'll have a 1000W inverter --> UPS --> TL-WR810N Router --> TL-SG1008P POE switch --> and 4 small ip cams.
The heater fan stopped blowing the other day. The fuses check out ok. What would be the most likely culprit after that? relay? Switch? Blower motor?
View 7 RepliesI don't think that my block heater is working correctly if not at all.
View 14 RepliesI tried a steel with rubber insert washer, but it still leaks. I might have overtightened or something. It seemed good for a while. Who has a solution for this leak?
View 14 Replies2003 CC 4x4 ... I am pretty sure I know what is going on, but I wanted to start a thread for when I confirm it. I am driving to work this AM and I hear the door ajar chime and I think to myself, uh oh...gauges all look good, there are no lights illuminated on the dash. I get to work and turn the truck off and my fan stays on. I think the ignition module is going bad. Either that, or my remote start is going on the fritz. I will update when I find out more.
View 3 RepliesI can't get my truck to start. The block heater isn't working and I previously put flush and water in it, intending to drive it and flush it directly after. Well I never really could drive it and now it won't start again. The weather is going to turn off cold, around zero this weekend. I need to know how to keep the block from freezing and cracking!
View 11 Replies I wanted to specifically ask about the block heater though. Since I bought this truck I never was able to start the truck without plugging it in. Now that it's not running I'm thinking much more about the block heater.
Is 56 too low for this old truck to start? What temp should a block heater have the oil temp as seen by AE be?
I live in the southwest so it's not very cold here. plugging in the heater was even required in the summer unless the truck had been running. What kinds of engine trouble would require being plugged in in warm conditions?
