Rough idle and no pedal response? - Page 3 - Diesel Forum

evo45 · 10-29-2012, 09:09 PM

The ipr duty cycle koeo is 14.7. I pulled the valve cover plugs while the engine was running and it stayed running when I pulled the drivers plug and died when the passengers plug. After that I pulled the drivers valve cover and I was disconnecting each injector while it was running and #3 back had no change in the idle. #1 seemed like it wasn't pumping any oil out compared to the other 3.

I have come to a conclusion that I damaged the injectors again after putting the Adrenaline in. I am guessing this because I pulled the fuel bowl out and didn't clean the bowl itself, I just changed the o-rings on the drain and put it back in. After doing that the trash that was in the bottom of the bowl must have been stirred up and went past the filter. I don't have the fuel bowl heater in the bowl so when I pulled the filter to change it, the filter and plastic tube pulled out. I am going to pull the injectors again and have them gone through.

Does it still pass a buzz test? Are you sure the correct injectors are buzzing??

Could be UVCH and/or VC gasket issue. Were these replaced? Did you use OE or aftermarket? (aftermarket sucks...) Have you done the '$0.50 mod'??

Could be an injector issue, but not my first suspect. I'm gonna re-read this thread and think about this a little more.

Yes it still passes a buzz test. I used an aftermarket vc gasket. I didn't do the .50 mod. I am still having a problem with the ICP not reading. The aeroforce is still reading 65000 but reads my dads truck fine. Not sure what else to do other than send the injectors back.

Can someone post up a diagram of the engine wire harness on an 01 f250. I am at a loss to what could be wrong. My only other option is that I somehow hooked up the ICP plug wrong. If that isn't the case I need to bring my new ICP back to Ford and try another new one.

Airfooter, when you say am I sure the correct injectors are buzzing what do you mean. I hear all the injectors buzz then they alternate back and forth on each injector for all 8 of them.

I am going to hold off on sending the injectors back to be gone through until I get the ICP reading on the Interceptor. I just can't figure out why it isn't reading all of the sudden.

I will run through what happened when the problem started.

I was driving down the road, came to a stop light and the trucks idle went really low, like 300 rpm. Did this at 2 lights and then died at the 3rd one. I pulled over and unplugged the ICP. Truck idled and ran fine. I bought a new ICP and plugged it in and it was idling like crap still. Took it for a test drive around my friends neighborhood and wouldn't go away.

I bought a new HPOP and ipr and installed those, no change. Bought an Aeroforce Interceptor to read codes and am getting the codes in the previous posts. When I clear them out the idle drops really low and then starts to surge again and all the codes come back.

Any suggestions or diagrams or the engine harness would be a huge help. I want my truck back!
Thanks

I figured out that my new ICP from Ford is bad. I removed the ICP from my truck and just plugged it into my dads truck and it was reading 3600 psi with the koeo. I plugged in my dads ICP that was still installed into the head and it was reading 26 psi koeo. I then went to my truck and plugged the ICP back in and it was reading 3600 psi and jumping up to 65000 psi. Would this cause the idle to surge and the ipr to jump around? Should I try to reinstall my old ipr and see if that changes anything with the idle?

I'm not sure that this is my only problem but I will post back if it is any better.

I installed the new icp and tho truck is idling and the interceptor is reading th icp now. It still isn't idling like it should. At idle the icp is reading from 600-650 and the ipr is reading 14-15. When I drive the truck the ipr will read 40% just barley taking off. When I can keep the truck running with the chip on it the ipr will read up to 50 taking off a little hard. The truck will still with the chip as soon as I let off the throttle. It runs great when it is moving.

There is no check engine code and the only dtc's I am getting are p0266, p0269 &p0278.

I had a whole book written and the iPad kicked me off the Internet! MF'er!

I ran another buzz test after that post and got 3 codes, 1272,1274,1276. I cleared them all out and drove the truck again and redid the buzz test and didn't get them again. I am taking a guess but it seems like the Adrenaline is pumping too much for the truck to idle correctly. Is that possible?

I know in my dads 02 F350 the Interceptor shows a different reading than in mine. It seems like when I am cruising down the road in my truck the ipr and ICP are reading a lot higher. When I have my chip plugged in, a DP-tuner F6, maybe a DP-Tuner guy will chime in, the truck will start and if I immediately hit the throttle it will rev, and I can take off. If it goes to idle the pedal will be dead. What does that mean? Any ideas?

I will try and get some more parameters tomorrow while I am driving it.

I decided to pull my injectors and see what they looked like since I was getting the contribution codes. When I did the injectors were more carboned up than they have ever been. I was going to just clean them and throw them back in but it is a lot of work to just have to pull them back out if that didn't help. I am going to send them back and have them gone through. I'll post back with what they come up with.
