[@Farseer1995]

Well done, sir, that's what proper diagnostics is for. It's so simple, when you think about it, fuel trim data... that's not complicated AND YET, YET, people (like that shop) were unable to find the fault. You hear stories like that all the time.

Clean and clear explanatory....thanks for your honest for saying that the customer should go back to the previous place that said they did that intake manfold, other mechanics or shops could have ripped that customer again for that thanks to show people that there are still good and honest mechanics out there, the issue is how to find them...great job my bro

… was just thinking how sequential and delibrate you do your diagnosis… sign of an honest effort… and how some other shops would not take as much time… and come to find out work had been done on the car for the same prob… there is no doubt she was had… being a female they walked over her… that thing was not replaced.

[@KITS_Auto_and_Truck_Repair]

Moun Bakko Thank you! the customer took the vehicle to the shop that initially worked on it, since they charged her a lot!

[@mounbakko5871]

@@KITS_Auto_and_Truck_Repair that was the right decision… it was their shit, let them deal with it… that is how dishonest they are… they rushed to change the intake (that is what they say… pure lie) just to get the woman’s money… do not get involved with it because you can end up getting dragged in some shit… you educated her with a good diagnosis… it is left to her to fight for her herself… you are an honest man unlike those crooks.

Great tutorial. My 2007 audi a4 giving a p0171. The car starts fine and idles around 1200 rpm then drops to 800 rpm and shakes. I unplugged the brake booster hose and the rpm stays same no change. Shouldn't the rpm rise because I am introducing more unmetered air? I am totally confused. Any help would be greatly appreciated. Thank you

Hi Deo. Do you know why the value of the MAF sensor was 0?

So to isolate this P0171 error, the easiest way is to use the smoke machine? or is there an easier method?

drsnowmon Smoke machine is the easiest way or you could use some soapy water, spray it around the intake manifold and see what happens!!

My short trims stay high at 25. And LTFT also doesn't change at high RPMs. Is it a fuel delivery problem? There is no vac leaking.

I’ve got a beetle that’s popping the lean code right now and I just had a massive repair done to it. I can’t help but feel that since I’m a woman, I’m being taken advantage of. It seems every time I get it back from the mechanic it’s something else. I’d rather go to the doctor and get bad news than even take my car to the mechanic (because I’m always told something is going on and that kicks off a cycle of chasing problems with it)
