blanking plate, goo, is exhaust paste, similar plate on exhaust manifold.

i think you may be wrong about that, the throtle valve is part of the egr system, nothing to do with engine stopping, not sure where that came from. it is in the manual, with full description. page 431 The ECM receives signals sent from the engine coolant temperature sensor, crankshaft position...

what type of consult for early models?:confused:

from personal experience, with VAG, renault and others, I have never been convinced with ecu based tests for MAF’s/MAP’s, as unless real odd readings, sense could be true. On VAG 1.9TDI to get VAG tool to show error, it had to be open or s/c. a failing one never showed, and that is main dealer...

i have before "changed" the fuel temp sense voltage, to great effect! ecu thinks hot fuel is less dense, so compensates, with more fuel.:naughty seems to work over complete range, might be woth doing?

i saw that opamp idea on the rover site, the bloke who posted it, is now marketing at £100 ish? just ups the game from standard, i guess at 5v it just max out, cant get more ?

the supply? in that case, anyone tried a diode from supply to ecu sense wire? should give 5v less about 0.6v out. how would the ecu react to that at tickover?

the 4th gear up hill test? i wouldnt try the diode one, only ever done it on vw's. i think the terrano is 12v feed to maf, output would be ttl 5v maximum i guess, i will look at it tomorow. on some cars with maf removed car goes to basic "map" on ecu, i guess with terrano it goes to limp mode...

some on ebay at mo, for abot £25 found new for about £75. not sure nissan price but would guess lots...... yours is hitachi?

on the drive at home, even at full throtle air mass is low, testing going up a hill will be sucking in huge volumes of air, if ecu doesnt see this air due to maf fault/failing, it will lower fuel ratio being injected, that combinded with the actual huge amount of air that is going in (but ecu...

MAF sensor. best way to test, drive up a hill in a high gear 4th ish. this at lowish speed loads engine the most, if symptoms get worse or are at worse, change maf.

what about if i link to an ftp site? i think you are correct, i just had another go, it seemed to upload, then didnt show them, how do people enbed them in post? hope my post isnt too long? got carried away, i have to admit i have the terrano bug, better than the flu bug i got two weeks ago...

Hello, re primera 2ltr petrol p11 model 97 99. use part number off Hitachi maf, end’s 200, same part! later maf, Bosch has inlet temperature sensor as well, hence extra wires on connector. I haven’t tried it, but I do wonder if it may be possible to retro fit a Bosch on the Hitachi...

rear left of the engine, back of inlet manifold. also check the throtle body on top of manifold, as this is designed to work in conjunction with EGR, so when more egr gas is flowing, clean air is throtled back by large butterfly flap. If vacume pipe to egr has been blocked in the past, the...

mini filter in mine, and i believe others, was for some odd reason in the return pipe, not the inlet, but yes in the banjo not the pump. also, the disconecting MAF, just proves it is not completly gone, not that is failing. trade test, drive up a hill3rd gear, does it feel at its very worse...

by chance came accross official nissan figures; Transmission: M5 Engine Size: 2664.00 cc Fuel Type: Diesel MPG Urban: 23.90 mpg MPG Extra-urban: 32.80 mpg MPG Combined: 28.80 mpg CO2 Emissions: 260.00 Euro Safety Standard: III Noise Level: 73.00

hello, no we are talking about maverick/terrano, just mentioned xtrail in conversation, sorry if it was confusing. not sure why maverick would have difernt values,all came out of same factory in spain. before ridding car of egr system i was getting 27mpg average, doing about 200 to 300...

i drive a lot for work, until 6 weeks ago i had a 57 plate xtrail. so cover mega miles, 27mpg is mixed driving pre egr and flap removal, did you blank off egr or do bearing insert? was your manifold clogged up? driving it now it seems so much more responsive, hopefly get the 33 or 30 as nissan...

hello, 27mpg is not what they sold them as, and to drive it now, it seems so much free'r, breathing properly. i had also read the vale was ashut down method, which struck me as odd, but refering to manual, i appear to be right buterfly closes at egr opens and vice versa, makes sense, or with...

wow just completed test drive, and wow!! upon power, easier to start, no smoke what so ever. i can now hear the turbo spooling up, never heard it before, to this extent. very worthwile way to spend weekend, i am hoping that the free breathing engine is now going to return some etra mpg, will top...
