Okay i have an 02' ford f-150 its 2 wheel drive with the 4.6L v8. I have an edge programmer and a s&b cold air intake. When i set my tune to a custom program on level 3 it throws trouble codes that say tps sensor (throttle position sensor) is inconsistent with mass air flow sensor and it burns a lot of gas on the custom tunes and blows alot of black smoke out of my super 44 turn down. When i set the tune to level 3 not on a custom tune or set it back to stock it throws trouble codes that say system running to lean bank 1 and it says bank 2 is running too lean too.. Whats going on and how do i fix this?! I've been told to run high octane fuel through it but ive ran several tanks through it and it still has yet to fix the problems. Is it my catalyic convertors going bad or is it my oxygen sensors?

 

I'd check for air leak/loose connections between the MAF and throttle body of your cold air intake. Could also be an air leak between exhaust manifold to engine and cat converter, broken manifold stud, etc. Your looking for sources of unmetered air that would cause the O2 sensors to read lean which will throw excessive fuel into the engine. I don't think I'd blame the programmer as you say the stock tune is also affected.

 

i also am pullin up a trouble code that is saying cylinder 1 is misfiring. So is my spark plugs going out or is what you told me causing them to go haywire too?

 

also when the last time you did the fuel filter

 

Although you never mentioned how many miles aprox are on the spark plugs, it doesn't matter as a spark plug can fail anytime. You have to fix the cyl 1 misfire as the pcm will try to adapt to the misfire.

Do a visual of your engine looking for loose/broken/disconnected wiring and vacuum lines. Fix the codes.

Disconnect the battery for a couple of minutes I believe it will reset the KAM (keep alive memory). This should start the pcm adaptive control fresh.

 

Okay heres the deal.. I went to my local o'reiley's store because i know a guy there who knows ford motors really well.. he told me it sounded like my maf sensor was dirty and told me to clean it and said that it was either that or my spark plug coils... Well i cleaned my maf sensor with carburetor cleaner and it still is givin me the same problems.. its throwing the trouble codes that bank 1 and 2 are both running lean and it sounds like its missing real bad.. HELP i dont want to have to pay 45 bucks an hour on labor for ford to work on for 3 or 4 days looking for the problem.. my truck is an 02' ford f-150 xlt with the 4.6l its 2 wheel drive it has approximately 70,000 miles...

HELP

 

If p0171 and p0174 you're getting air into the intake system AFTER the mass air flow sensor. Check for vacuum leak(s) common problem is the rubber boots used on the vacuum lines gettin old, the one on the back of the intake for example .. also check the line near the EGR.

 

Thanks i'll check all this asap and let you know if that fixed my problem or not

 

In order to stay out of confusion, the following questions need to have a solid answer.
1.Is everything ok on stock tune? No codes, driveabilty etc.
2. Problems only when you go to aftermarket tune?
Mass air meter issues can cause lean codes but as I read your discription, the performance program is interpeting the mass air signal incorrect and over fuels the motor causeing poor fuel mileage.
If you can get a line on what does what and when, you may need to get back to the programmer about you issue.
You seem to be deep into trouble shooting involving reprogramming the PCM, so you need some expertise to be applied over just troubleshooting a stock motor.
Said another way, you need to sort out if the programer has a program bug or the motor has hardware problems.
Good luck.

 

well see heres the deal i called edge about that and they never returned my calls i called them back for a month and i got the same answer saying that a engineer was looking at my programmer for bugs and i never got a phone call back.. when i go back to the stock tune it pulls up the obdii error or whatever it is... I keep my programmer on level 3 no custom tune because when its on the custom tune it idles higher and blows black smoke out of my turn down.. I dont think it has anything to do with my tuner but yet im not sure because edge is crappy on their customer service... I didn't get a chance to check my vacuum lines today but i will be doing that tomorrow and getting back to you guys.. My moms boyfriend is a mechanic and he can't even figure out what's wrong with it... We dont want to take it to the local ford dealership till we can get a good guess on what the problem is because of high labor...

 

In my opinion, you have a decision to make or put up with the issues.
At this point, I would have the PCM dealer reflashed back to sock program so you have a baseline to start with for solving any issues in stock form, that are present.
With the present situation you don't know what is going on or how to solve it with two possible unknowns.
Then if you change programs again, your apt to get right back into the same situation again and have to reflash the second time.
I have been in your shoes and done it, so consider what I have related to you.
The EDGE for some, is a no-no with no support.
Mine works good as a monitor and is what it's used for since I got into a bad situation with no support 4 years ago.
Since then I have been on stock program, towed up to 12,000 lbs gross, have 142,000 miles and still love the truck for how well it runs.
Take the advice; bite the bullet and get it reflashed stock. Be sure to take along 2 keys or the reflash can't be completed.
Should only take 45 minutes or less.
Then if your still bound to do the program trying to get more performance, at least go to Troyer for the package and support.
Remember you may want to sell the truck some time so it needs to run correctly without the programmer or the next owner would have a problem.
Good luck.

 

here's some new information....

I am now pulling up trouble codes that say this...

p1131 lack of (HO2S11) switch sensor indicates lean

p1151 lack of (HO2S21) switch sensor indicates lean

Sorry guys i just havent had time to work on my truck because i'm a busy college student.. It seems like my gas drains really quick now. Please help!

 

Is this a previously owned tuner that's maybe programed for no cat convertors/off road use? Just guessing.

 

You need to study how OBDII works so you have a better idea of what is going on here. Ford truck engines have several very common problems. COPs, Clogged EGR passages and vacuum hoses that have holes in them that cause P0171 and 174. All are good money makers for Ford dealerships and independant shops. Hopefully Ford won't change this any time soon. The TPS and MAF are best friends. You can unplug one or the other and the engine will still run(probably like crap), but you can't disconnect them both at the same time or the ECM has no way of knowing how much air is being pulled into the engine which means it can't determine injector pulse width. It's unusual to hear of a scan tool that rats out the MAF and tells you the TPS and MAF aren't getting along so good these days. Usually you'd have a DTC for either the TPS or the MAF instead of it telling you they don't agree. You can go to a local independant shop that has a J2534 pass through device to get a reflash done. They will be cheaper than the Ford Dealer. Many times a reflash will clear up a lot of driveability issues.

 

I recently had a similar problem with my truck. First time ever that the CEL came on with a little over 100K miles on it. The problem started out with just the CEL and P0171 and P0174 DTCs.
After a few months of neglecting diagnosing the problem, the engine started staling on me during normal driving usually at a stop. I checked the codes again and found the same two plus P1131 and P1151.
As soon as I had the opportunity to get under the hood, I found a rubber elbow in the PCV to intake manifold line that had a hole in it. I knew that this was the trouble as soon as with the engine running very roughly, putting my finger over the hole in the vacuum line, the engine ran smoothly. Good luck!
