So I took my truck in to get looked at today because I thought it had been running a little funny and here is a list of things I had them check out. Truck seems to idle a little weird sometimes, the motor when sitting parked sounds like it is making a ticking noise and also sounds like there is an exhaust leak (ticking or weird noises are especially heard when you go through the drive thru at any place), It also seemed like it was shifting weird because if you gunned the throttle and then let off it would rev up to a certain rpm and then it would not drop back down all of the sudden like it would hold the rev for a second and then slowly go back down and also when you would step back on the gas before it dropped back down it would just rev up to a certain rpm until it decided to shift....it seemed strange to me but maybe its not?...Also when you accelerate hard there is a noise that sounds like an exhaust leak or maybe it is just the exhaust noise that will get louder but it only does it when you accelerate a little harder...

So they took it out for a test drive and hooked it up to a scanner/computer I believe and they said they didn't seem to find anything wrong except for re-writing the pcm I believe is what he said for some shift update which this is what it said on the work order below.

IDR Test Re-program as per TSB, 08-14-03, Trans Shift.....What does this mean?

I am thinking of taking it to a different Ford Dealer and have them look at the problems because the truck seems to run good but it is just at weird times something will happen to where I think something is wrong so I don't know what to do..

I have an 08 F-150 Supercrew 4x4 V8 5.4 with 6,000 miles on it and I did have the edge programmer on it for a few thousand miles until I removed it before I took it in thinking it was causing some issues. Which could it have made some of these worse or caused them to stay on even after I removed it? I just don't know what to do and the service guy said this to me before I left "You have plenty of warranty left so just see how it runs and just let me know if there are any problems."??? Well obviously I think there is a problem and they don't seem to find anything...Sorry for the long post but I just have a lot of stuff on my mind and wanted to get it all out and just want to make sure my truck is running right because it is new and I don't want to keep thinking that something is wrong with it. Any input guys?

 

to me the ticking noise sounds its just the injectors ticking or the cam phasers going early. did/do you have any other mods on your truck besides the edge(cold air induction, tb spacer, reusable air filter, etc.). and what do you mean it idles weird? low? high? jumps up and down? and how long have the tranny and idle issues been going on?

 

I also have similar issues with my truck. I had the cam phasers replaced and that eliminated the knock, but the injector tick is typical, as annoying as it is. The tranny shudder though I took to 3 different dealerships while under warranty and all I ever got was the same response you did, " you have plenty of warranty left, if the problem persists bring it back." Now that I am out of warranty they want the truck back because they may have a solution but I must pay $159.95 for a tranny "specialist" to inform me after he "addresses" the complaint. My advice is while you still have a warranty push the issue and build an extensive paper trail. I didn't take the time and I should have.

 

Hey guys I had a S&B cold air intake put on about a month ago and only ran it for like 2-300 miles and didn't like it so I switched back to the stock setup but other than that and the edge is the only two things I have tried on it...Also the idle problem occurred one day when I was at a stop light and turned on the a/c and it started to jump all over the place and the truck was shaking but then it went away after turning the corner and driving away...it also happened last week when i pulled into a parking lot and stopped suddenly to back up and drive to a parking spot and once I put it in reverse it started shaking and rpm's were jumping all over place and so i started driving it to the spot and once I parked it it was still doing it so I shut the engine off and waited a second until turning it back on and it didn't do it. These happened with the edge on but the second one didn't occur until 2 weeks after the first one did and I drove it quite a bit in between there. I removed the edge last Wednesday and haven't had it come back again so maybe it was the edge that caused it??

 

alot of people just clean there throttle body plates and it clears up the idling issue. some replace the whole throttle body. the filter from the intake may have contaminated something. so that would be the first thing i'd suggest you try. with the a/c on does the rpm raise any?

 

a 2008 with 6000 miles? I doubt the throttle body is clogged.

Like others have said, if your not happy... keep pushing the problem to them, or try another dealer.

The ticking is almost always the injectors (especially considering its a new truck). As for the transmission, you could possible have a problem or its just different from what your used to in an automatic. I went from a 1999 Honda Accord (high-school, rice burners were the ticket to being the first in your group to declare non-viriginism) to a 2005 F-150 this year, and its a very large difference. I know that's like comparing apples and oranges, but I don't know... something to consider (difference in types of tranny).

I've always thought of my F-150's transmission as being a little odd, but its given me no problems what-so-ever. I did once bring it to a dealer, and they also performed the flash for my truck, which improved it.

Custom tunes can always help too

 

It seems to idle fine it was just that occurrence last week and with the a/c but when the a/c is on the rpm's will go up a little bit but not much...And when it did the shaking from the two occurrences the rpm's were all over the place but didn't jump that high it was just running rough like it was going to die....? But it was weird how it came out of it the first time from driving away and the second time it didn't come out of it from when I put it in reverse and drove it to the parking spot??...

 

not clogged but maybe something got contaminated. like the maf or the electronic throttle body.

 

I think I am just going to schedule an appointment next week at another dealer just to start fresh and the dealer I want to try is one of the bigger ones in the state so hopefully they might know something or help me out a little better....I live in North Central Iowa and I go to college at Iowa State University in Ames and I just went to the local dealer here at school but Des Moines has like 3 or 4 dealerships which is about 25-30 minutes away and they are the largest ones in the state but I bought my truck from Woodhouse in Blair, NE so I don't really want to take it that far to have it looked at.

I will see what I can find out but I just never know how to explain the problems I am experiencing because they may just be normal and seem odd to me, but the ticking or weird noises when it idles just doesn't seem right even though the dealer says they can't hear it. This also makes me think that I should actually be around when they are listening to it so that I can tell them exactly what I am hearing and where I think it is coming from instead of just telling them it doesn't sound right and they probably don't even check it out! Also the noise that sounds like an exhaust leak when you accelerate moderately to hard sounds like it shouldn't be their either but I am going to drive it for a few more days with the tranny update they did today and see if it helped....

I just get worried that something isn't right when I hear something that I think is a little louder or doesn't function like I think it should being a brand new truck.

Hopefully I can get some answers somewhere soon or if something isn't right I can get it fixed because that is all I think about almost everyday!

 

slvrbrute,

Did you ever figure out what was wrong with your truck and the rough idle?

My 2007 f150 5.4 3v has similar symptoms. It has happened twice. When put in reverse the engine would run rough and has a ticking noise. I was able to stop it by putting in neutral, even though it still idled rough, and then rev the engine and it went away. Both times it happened when trying to park the truck after a long highway drive.

I haven't taken it to a dealer yet. the truck is automatic with 77,000 miles.
