Lean Code Problem
Lean Code Problem Alright...I've been gettting this code since this past March, and I've done practially everything that everyone has told me to try....and still nothing...I'm at my end...any last ideas before I blow the $500 on a dyno tune?
p0171 p0174 Lean Bank 1 & 2. I've been told to clean my MAF, check for vacuum leaks, change my O2's, clean the intake element, run the stock MAF and tune, change the fuel filter, check my injectors, check my fuel pressure....and I still have no leads...
so what was your fuel pressure? For it to be lean on both sides it's likely not sticking injectors, as that woulds require one on each side to stick.... probably a fuel pressure problem.... fresh O2s in the car as well?
Fresh O2's....my friend pluged into my car with EFI live...he said my fuel pressure was good and my injectors were working fine....so idk...I've been dealing with this problem since March...and I need to fix it.....

Verdad Gallardo You can't check FP like that... you have to actually check it, and do it at the rail.
SLP LT's, SLP LM1, SLP Lid and Intake Kit, Granatelli MAF, Diablo Sport Tune, AIR Delete....thats about it...and as for the FP...I'll get on checking that...what is ideal FP on a stock motor???
just my $.02. I had the same code on bank 1 after I put duals on. I thought it was a tuning prob, had my tuner flash in different fuel tabels and the code came back after 50 or so miles. Come to find out it was a loose exhaust connection on the driver side collector! f%$king with the O2. I changed O2s also prior to the new tables. Check those clamps. I got the same LTs so I bet that's the prob, I hope.
it takes like 5 minutes to check FP... Not being a dick but you keep bumping this looking for advice but you don't take it.
The only other thing that I know of (cant look at EFIL logs) is I have seen those granatelli MAFs read all over the board. If it were mine I'd throw it in the woods... or at least ebay it.
What did you friend's wideband show at WOT with that thing?

BUMP
I'm still trying to get a gauge to check my FP....and I don't remember what the wideband said....and as for the MAF....I tried with with the stock MAF and same old problem...

I tuned a car this afternoon that had headers and ORY, slp lid, and slp MAF. At idle, the LTFTs were maxxed at +25 and the STFTs averaged about +6 to +8, and the fuel pressure was good. This MAF deviated from the factory MAF table from 25+% in many places. Yes, it was nice and clean. The car was stupid lean, inital street tuning showed 18:1 at WOT WITH very high LTFTs.
