Turck Surges, more so when accellerating - Diesel Forum

jobremski · 08-22-2006, 06:34 PM

I have been noticing my truck seems to surge like I was just tapping my foot on the gas pedal constantly. I've have a Banks exaust on the truck and it came with the wrong TOP pipe so I don't have the resenator to get rid of the turbo wistle (which to me is fine and dandy) so I can really hear the wistle of the turbo going up and down constantly.

I took it to Ford delership yesterday ($200 diag fee) and they wanted to charge me $700 to install a new mass air flow sensor. I told them thanks anyway and I can replace the unit by unscrewing 3 screws, 1 wire connection myself. They said it went bad becasue I have a K&N air filter and the oil from the filter some how messed up the sensor. Uh ok, never heard of this before in any of the 8 other vehicles over the years I've owned that all had K&N filters installed nor anyone else having this problem.

I tried finding a new one at Autozone but they can not order it but the guy at the counter suggested taking it out and brake cleaning it and see what happens. I tried that and unfortunatly no go, still surging. I seriously have my doubts that the MAF sensor is to blame to begin with.

Anyone else have this problem? What was the soluton? If MAF sensor, anyone know where I can get a MAF sensor besides the $200+ one at the delearship.

Joe,

Is your truck black-listed in Oasis now? & which dealer did you take it to? I may have a suggestion depending on your answers.

As far as K&N filters fouling sensors and the like, I've heard that for years....especially when lashed up to a turbo-charged vehicles.

I took my wifes in for some warranty work and they didn't hook up the MAF sensor. We drove it for a week that way until I found it. Didn't drive any different hooked or unhooked and no SES light.

Never heard of the Oasis list, what is that?

I took it to Team Ford in Las Vegas off Ann road and '95.

The guy said they "did a diagnostic" $200 and came back with the mass air flow sensor. I bought one that was in stock at the other Ford delership across town and replaced ot and the truck still has the surging problem.

Guess the Team Ford guy was full of it, especially when he quoted me $700 to replace it to begin with. Took about 30 seconds to remove 2 screws. Now I want to go back there in the morning and get my $200 "Diagnostic fee" back.

Obvoisly the original MAF sensor is fine and the K&N is not the problem. Would the MAF sensor normally be covered under the 100,000 mile warranty? I think they were using the K&N to get out of covering it even though that was not the problem.

Joe,

Couple of things here, some your fault, some dealer's fault. OASIS is Ford's computer tracking & diagnostic system of maintenance/warranty repairs done at a Ford dealer. If a vehicle is denied warranty repair, its entered into OASIS so the next dealer knows it too.

On the 03/04's the MAF senesor originally wasn't as critical as it is after the 06E17 recallibration., and YES the K&N is part of your problem. I don't like 'em personally & would not consider one for my truck (or any AM airbox, for that matter). To properly maintain a K&N, you need to clean/oil regularly, and that oil WILL mess with the MAF.

Your truck has been modified in such a way as to give Ford grounds to deny warranty repair regaurdless of the 100k/5y status. If you had not modified it, yes the MAF would have been covered w/ a $100 deductible (after the 3/36 gave our). A dealer charge of $200 for diagnostic is about $100 too much. The K&N IS grounds to deny warranty, as is the edge, and the banks exhaust. Both the air filter and exhaust play important roles in how the PCM controlls the engine, and you are now out of factory spec, so I'd expect more troubles with it, and your recousre is now with Edge, K&N, and Banks, not Ford.

I know its not what you wanted to hear, but the 6.0 was tweaked to within an inch of its performance life when it left the factory. The 7.3 mind set of adding "enhancements" has caused more than one owner grief.

Rich807 · 08-23-2006, 10:24 AM

Oasis, among other things is the "database" (for lack of the proper designation) that Ford uses to catalog information about your vehicle. If a dealer puts in a VIN the system will come back and show it's service history, any outstanding recalls needed, AND most importantly to you guys that are modified......if your truck has been "black listed" in the system i.e. voided warranty. This happens a lot when folks take their trucks in for warranty work and a dealer finds aftermarket performance stuff attached to your rig. Not all dealers will flag your truck but a lot will. Long story short you need to find out if your truck has been flagged in Oasis, if it has you're toast for getting any warranty work done. There are folks on this board and others that will run an Oasis for you if you give them your VIN. This is done on the D.L. as guys could get in trouble for doing it, so you need to ask (post) nicely for someone to do it for ya.

Now, as far as Team Ford. They tried to jam one of my employees for a bunch of money last fall, he refused and was telling me about it. I sent him to a special place I know of and they hooked him right up under warranty. The work was for a total warranty item and they (Team Ford) tried to charge him. It sounds to me like they're trying the same with you UNLESS your truck has had it's warranty voided (but you should know that if it has been voided). I will PM (private message) you in a few minutes with some more information, so check your PM's.

You're playing with fire with your Edge and other mods though,just be aware that Ford (and other makers) are on the prowl looking for reasons to void folks' warranties for aftermarket mods.......it's no joke.

Mine was doing the same thing and the dealer replaced the turbo, it seems to have solved the problem.

jobremski · 08-23-2006, 01:53 PM

Well I dropped it back off this morning and explained to the rep the step I took a) swapped mass airflow sensor with a brand new one b) did a quick test up and down the street with NO K&N (since the tech blamed the problem on K&N oil) and the problem was still there. The rep put it back into the shop. This time without putting me down for the $200 diagnostic. We'll see what they come up with now.

At this point I guess there is not much to go on as to what is causing it, maybe turbo but honestly a lot of things could cause the pitch of the turbo to change and the surging I'm feeling, engine load, RPMs, boost pressure fluctuating etc so I'm at a loss right now. I had the truck in for some tranny work about 2 weeks ago so I was even thinking maybe the tranny is messed up and it's changing the load on the engine. I have a lot of theories but no way to test them [img]/ubbthreads/images/graemlins/smile.gif[/img]

Joe,

Did you read your private message from me yet?

dvtech · 08-23-2006, 02:20 PM

[img]/ubbthreads/images/graemlins/smokin.gif[/img]hey! read my post on attn. 6.0L owners. & perform that procedure & see if it might fix it. [img]/ubbthreads/images/graemlins/smile.gif[/img]

jobremski · 08-23-2006, 08:57 PM

Got an update from the delarship, "We cannot acuratly test the vehicle without the stock airbox on the vehicle."

Here we go again. Luckly I have a buddy with and '04 F350 6.0L and he is going to let me "Borrow" his box tomorrow for the duration of the delars tests.

Rich807 · 08-24-2006, 09:52 AM

Joe,

GET YOUR TRUCK OUT OF THAT DEALERSHIP! You're playing with fire with them and you have a much much better alternative that will most likely not put you through all this crap.

Out.

jobremski · 08-24-2006, 01:20 PM

Yeah I think that is the plan. I'm pedaling my way over there shortly to pickup my truck then drop at the place you suggested. I called the new service place up and explained my situation with the dealer and they said the same things I'm thinking that the air filter is not causing my problems nor the inability to properly test the problem.
