Why does my Nissan Terrano 2.7 turbo diesel have no power?

Nissan Terrano 2.7 turbo diesel starts ok but has no pulling power, painfully slow at pulling away and speed drops drastically on the slightest of gradient. Appears some kind of a fuel problem?

    Check the exhaust recycling valves, across the back of the engine there is a pipe where exhaust is fed back into the intake manifold while cruising and idle. I had a problem with this due to throttle position sensor not sending the right signals to control the valves. I disabled the valves so that it did not recycle or restrict the airflow with the butterfly valve on the air intake. Before fixing it the car would blow huge clouds black smoke when accelerating.

I had the same problem . Local dealer did not seem to know the solution. Eventually trawling these pages I tried changing the air mass metering unit which I got from ebay dealer for about £30 something. The change in performance was staggering. I believe you can clean the unit with a solvent too. It is easy to change yourself and is in line after air filter. Ed

Guys

I had a similar problem with lack of power, not noticeable aroundtown but really noticeable on dual carriageway. Gear change on the automatic box wasn't as smooth as normal and Couldn't rev past 3500, on full throttle , white blue smoke , sounded like a misfire, but only happened on wide open throttle. Suspected fuel starvation so :
Changed fuel filter -no difference.
Disconnected and blew air down the fuelpipes, felt quite difficult and tasted horrible.
Took tank sender out , checked swirl on pickup that was slightly dirty in colour but free of blockage .
Then noticed if I pressurised the lift pump the engine revved better but only for a couple of revs. I had previously tried to find the filter in the banjo on the fuel pump to no avail, but I'd covered off all of the other easy stuff, so went back to the banjo again. This time I removed the spring under the banjo bolt, dug deeper (about 7CM's) into the pump fetched the banjo out, spring out then I had to make long thin hook to fetch the tiny filter out. It was filthy,nearly 20 years of use,probably never been removed before. I did break it getting it out, so left it out, Nissan did the same sometimes

Oh my God, what a difference, its the best its ever been.

Hope this helps others .. thanks

    IT is the needle valve in the injector pump, being fly by wire there are two magnets that drive the needle up and down governing the flow of fuel. this is the issue with these pumps.

Ok, here is another possibility. I was driving and went to overtake, part way through the overtake, the engine just died, eased off on the throttle, to get a little power back, by 200km (120 miles) later, I could barely get to 100 km/h on flat road. Basically the engine was getting starved of fuel when it needed more. So I got a new fuel filter, by another 200km I could only do 50km/h on hills and 80km/h downhill. I was hoping to make it home without having to replace it at night, but that was becoming impossible. I pulled over and replaced the fuel filter (left side of engine bay against fire wall) and bled the fuel system by manually pumping the button on top of the fuel filter, until resistance is felt - this can take a while, as the filter is completely empty, and if you start the engine and it dies, then you haven't pumped it enough. I had to undo the 2 x 12mm bolts which hold the filter mount, to get a good grip to unscrew the filter .

I had this and solved it. Take off Mass Air Flow Meter and spray a whole can of WURTH CONTACT WASH AND CLEAN. Whilst you are spraying on the MAF, put a plastic bahind it so that you can collect the spray int it. Put the MAF in the bag with this contact cleaner spray and leave it there for a couple of hours. Blow dry it with compressed air and mount it again back. That's it, !!

My 1992 nissan terrano blows to much black smoke .how to fix this .some say i have unbirt fuel?


if diesel and turbo , check turbo operation of for holes in the intercooler
if turbo or naturally aspirated check/ replace injector tips as black smoke indicators squirting and not atomizing
if petrol check for excessive fuel pressure, faulty injectors , leaking injector seal
regardless of petrol or diesel --black smoke indicates incorrect air / fuel ratio ( too much fuel) so injectors, intercooler, bad turbo or blocked air cleaner are all candidates for the fault

Nissan terrano turbo diesel 1998 has lost it's power why


WHEN IS THE LAST TIME YOU CHANGED/CLEANED THE EXTERNAL FUEL FILTER...IF IT HAS ONE? ALSO CHECK THE AIR CLEANER AND ALL ASPIRATING EQUIPMENT FOR BLOCKAGE.
SOMETIMES, MICE, CHIPMUNKS, SQUIRRELS, ETC...WILL BUILT A NEST IN AN INTAKE HOUSE, THE FILTER BOX, AND RESTRICT AIR/FUEL FLOW. CHECK THESE FIRST

I have a Nissan terrano 1996 3200 diesel turbo. I,m getting between 400 - 450 km out of a tank(70l) It seems to lack power to, really battles to town a trailer about 800 kgs. Is this normal?


no it is not normal. There should be a variable vane turbo on the engine and it there is you will find an actuator in the middle that actuates the vanes around the turbine wheel to give the right boost for the engine rpm and load. Because these vanes work in the exhaust gas they tend to rust and bind up and not move and the rubber hose from the vacuum supply tends to get hard and crack. Check the movement by pulling up on the rod out of the actuator. To test for other problems I recommend you find a good mechanic that has a chassis dyno available where the actual engine performance can be checked in operating conditions. It may cost a few dollars but you will find all the faults and have it fixed all in one go.

1999 nissan terrano diesel turbo is lacking power , brand new fuel pump and comp chip installed and has run like **** since, has been put through comp diagnosis but no fault showing,(is very slow 2 pickup...


Possibly the "Mass airflow sensor". I had a similar problem, basically the car behaved like it didn't have a turbo and was really slow. Unfortunately the Mass airflow sensor is expensive, about AU$800. Only failed once several years ago. Hope this helps.
