My 2003 ZD30 regularly looses power under load and dumps smoke out the exhaust. Have had the turbo checked and is mechanically good but mechanic suggests air flow sensor may be faulty. Any thoughts on this?

Why didn't he replace it then? He may be right.
Sorry all, have just read the thread under mechanical by YNOT on MAF cleaning. great advice here so will give it a go.
pete,
check the MAF but ensure it has a good earth. Mine earths under the plastic engine cover on the left (facing the front of the car) under the intercooler.
If you have not recently changed your fuel filter, consider that. This was my main issue leading me down the garden path.
Car running sweet now, and also with a new MAF.
I had issues with mine (ZD30 loosing power) and there was heaps of things I checked so if you get stuck for things to check, look it up.
06 GU IV Nissan Patrol wagon 3.0L, Tough Dog 2" lift, Xrox bar, 12k Mako winch, 33" muddies, 3" exhaust, Awning, UHF, drawers & fridge, custom sliders, DVDs, custom water tank and pump, rack etc etc.
Now just in - GQ Shorty 4.2 petrol, UHF - but looking at turbo or V8 conversion
Even though mine has a catch can, the mechanic I take it to always cleans the MAF at every service. He says he does that to all 3L Patrols.Originally Posted by pete2004
What mods have you done Pete? If throttle pedal just drops to the floor it will be an over boost issue and you will need to fit a dawes valve etc.
Drive is 04 DX wagon, 165Ks, Dual Batts, 12000kg Warn in steel bar, Snorkel, Xray 220 Hid Spots, Cruise, digital EGT, Draws in back with power box, 40Ltr Waeco for the essentuals
AS Choppie says it may be over boosting, time to fit some guages so you can monitor whats going on instead of guessing.
Take engine cover off and make sure all your hoses are tight, change all clamps to constant pressure too by far best hose clamps going around
Sounds like you need to NAD it

04 ST 3lt auto, not enough Mods to keep me happy, but getting there
Still going on this issue. Cleaned MAF, replaced fuel filter, then found turbo inlet hose cracked. Eventually replaced inlet hose with one from wreckers. Problem of no power and brown smoke still occuring but less often. Water in Fuel warning light came on yesterday but did not come on again once engine restarted. Opened drain in fuel filter but only fuel come out. Any thoughts on any connection between problem and warning light? Whats a NAD?. Is the MAF really necessary - has anyone a method of bypassing these complicated bits?
Pete
You need the MAF, as this tells the engine how much air is going in and at what temperature, so it can adjust the amount of fuel required.
Depending on how old yours is, I would look at replacing it, or swapping for a known good on ( To Test )e, if you know someone with the same model as yours.
There are a couple of different part numbers according to the year, one for Series 2,3 - up to 2004, and one for the later years.

No point bypassing the problem mate it will always b there, bandaid solutions r no good especially if u go bush. You really need to install atleast a boost gauge to see whats hapening n also egt. Nissan anti detonation system is nads
