Can I swap O2 sensors by soldering?

[sevenleaf]

I wonder...

Could the carbon traces on your footpedal be suspect at this point?

I think so.

I don't understand can you explain. I'm ready to drive the thing into a brick wall.

Our cars have no cable. "Drive by wire" it's called. The pedal travels on a carbon strip to trasmit its position to the PCM. There is a post here that discusses a throttle lag (response) fix by taking the pedal apart and moving the copper strips or something similar to that. In the end the OP didn;t fair well in terms of the heckling if I remember right. NOt eveyone agreed with him here. A search and review of that lengthy thread would yeild a pretty good picture of what I am thinking about. I think you may want to swap out a pedal (new one perhaps) or take yours apart and check it out. I suggest this because of your description of your probem, the failed attempts to fix it and the possible oversite of this pedal control.

I remember that thread, the metal strips on the pedal he bent them to increase throttle response. I will think about it but I'm going to say sometihng is just straight up fucked.

I am working with pro dyno now I figure what the hell time to dish out another 500 bucks, lucky for me dan at pro dyno if he can't fix it with the tune I only pay 65 dollars. I have an appointment at the end of this month or the first week of next month. With mustang week and all. I'm going to pay to fix this shit I want it done I want to stop fucking with this crapo car. I don't want to deal with it anymore!!!

Ok I'm done ranting coors had some help with that. I'm getting blato'd I have a vacation day tomorrow.

Enough is enough!! I just reloaded the first tune Adam did for me that was running awesome.. It seems like the AFR isn't as bad but it was avg 15 - 17 now at throttle. Something that controls the afr is out of wack...

When was the last time you pulled the plugs?

I looked at this thread and you are getting real lean. My car barely hits 14 -15. I average 10-11's on AFR with my wide band PLX.

I know my tune is fat since I run Nitrous.

If the engine rev's then the peddle isn't a problem as it would not open the TB. You say you dont know anyone with a boosted stang Have you looked into any local mustang clubs. I bet there has to be some around there. Maybe someone there has a mafia you could try.

My problem with this is that you say you dont have any codes. there are some codes a Xcal and similar programmers wont show and only can be read by a dealer. Here is where a local club can help.

A lot of time a local club will have a in with a dealership.
You need someone who can look deeper into your PCM ECU without notifying corporate.

I would also start looking at any wires or harnesses that have been moved or disrupted in any way. you may have some type of intermittent ground going on. double check the O2 sensors that they didnt get up against a manifold and melt a spot. to me that would still send a faulty O2 code.

Too bad your datalogging messed up on you. A complete output file might be more useful to look at. The single snapshot doesn't show anything really out of whack. Although the long-term fuel trims are showing a little below the 1.0 norm.
Can you datalog the intake air flow rate and throttle position? (remove the short term fuel trims if you need to to have enogh pids). That would show how the maf and any throttle issues.

As you've suggested, you can just let the tuner try to figure it out, too.

I do not believe it is an oxygen sensor issue, but if you really want to change them, buy the pins from Ford, take the safety clip out of the stock connector, pull the pins out, and put the connector on your new pins, pop the safety lock back in.

 

[sevenleaf]

I'm going to start with a MAF I really wish I could get it fixed before Mustang Week but thats just the way it goes.

I attached 3 datalogging I did for pro dyno incase someone can work their magic for me.

Thanks everyone for suggestions.

Had a awesome day at myrtle beach today the weather was awesome and the waves were tons of fun.

Let me ask a dumb question....

When you originally had your car tuned, you had the aftermarket CAI on it, right?

While I am 99% sure you did, the 1% in me made me ask that! I had a K&N on mine. Just for shits and giggles (knowing full well I would need a retune), I put on a Steeda unit. Holy shit did that thing run absolutely crazy and weird. Barely would idle.

After Manny re-tuned it for me with the Steeda in place, it ran great but had that bog in it that he datalogged and tweaked out as we made circle after circle through his parking lot onto the highway.

Hope this helps.

Yes I had the steeda on and it ran great, I even swapped to the saleen extreme setup with no luck.

The car was running 100% awesome then overnight this problem devolped.

Ok took some video's they are not the greatest but maybe someone will see something.

are you using diablo? if i tweak a tune more than twice it reads the tune on top of the tune and goes extremely lean. I have to reset my whole car and tuner to stock to get it to work

just the stock MAS with a steeda 90mm MAF, did you say i should return my car to stock with my XCAL then upload the tune again?

 

[Dex]

Thats what I had to do with my Diablo. It keeps reading the tune over the tune and not the original file. Reset the tool and car but make sure you have your tune saved on your computer

I'll give it a shot and see what happens,

Step1> Return car to stock
Step2> Erase the XCAL2
Step3> Liveload tune back to xcal
Step4> Install new tune.

 

[Dex]

yep

 

[sevenleaf]

yep

No luck, Was a little worried something would go wrong tho, everything started up fine.

I ordered a new MAS to rule that out so only a few more parts left, pretty soon I'll have everything replaced within a year.

 

[Dex]

bummer man. sorry

 

[Cali HP Addict]

Sounds like the MAF meter to me.

I hope so, would make this easier. I have one on order, the MAF Sensor is expensive. Retails for like $240 I got one for $120. Should be here tomorrow or Monday.

Problem Fixed!!!!!!!!!!!!!! Finally




Ok My problem is fixed. Can you guess what is was?????



I replaced the MAF sensor no luck so that wasn't it. I found a vacuum leak at the boost gauge that wasn't it. I installed the 10% overdrive crank pulley that wasn't it. I installed the GT500 fuel system that wasn't it. I replaced the stock FPDM that wasn't it. I swapped to a 90 mm idler pulley, I swapped to a bigger belt. Nothing worked. Tuner sent me a about 6 tunes to try and fix the problem No luck.

I took some compressed air sprayed the shit out of the inside of the fuel injectors let everything dry did it again. Went for a drive and well shit. The car was driving soooooo much better.

ok well I experienced this before so I drive for about 40 minutes having tons of fun go home and wait since i figure it's just a fluke, I'll take my injectors and get them cleaned correctly Monday but WOW night and day difference.

A couple of clogged injectors, Who would have guessed. My car is no longer running lean and gurggling. I am 100% happy. I parked the car went for another fun drive met a few cars that wanted to have some fun my car finally kicked ass. I was getting pretty embarrased when I got on the throttle I didn't want to drive it anymore.

!!!!!

Problem FIXED !!!!!!!!!!!!!!!!!!!!!!!!!!!
