hi all does anyone know what fault code 43 is on a mr2 turbo 1990 pls

just under 85% its now around 83% iv reset the ecu and it went down a tiny bit, on full throttle boost (1.2bar) it goes to 85%. i did find out i had a faulty o2 sensor tho and changed that. i cant work any of it out, hope a good rolling road day mite help all these problems. unless anyone could shed...

iv got all the vacumes running fine now, just to check what duty should the injectors be running at? according to my apexi avcr there runnig at 85% on tickover???

yeah very good point espically as it took me 6 month to rebuild the thing. thanks for your help much apricated

it goes to zero in 10-20 seconds? also hear a creaking noise (when the engine is hot) coming from the fuel rail area and because of the loss of pressue thought it mite be a leaking injector seal/injector

also i have noticed something else, when the engine is turned off the guage on the fpr drops to zero, shouldnt it hold the pressure in the fuel rail?

i have a apexi avcr which is plumed into the map sensor and that reads fine tho? could it be down to a faulty map sensor? just double checked all the pipes and they all ok

soz make that behind injector no 3

on the very top of the fuel rail theres the really thin plate that has a tiny pipe coming from it, just behind injector 2? has 3 10mm bolts that screw into the lower part of the fuel rail that the injectors sit in, or am i just being completley stupid?

yeah all i done was replace the regulator so used the orignal vacuum line coming from the top of the fuel rail, just very strange that nothing is there now??

hi all hopeing someone can help me out here, iv recently rebuilt my mr2 and for some reason i have no vacuum coming from my fuel rail, i found this out when i was setting up the fuel pressure (40psi). i know it was there before i rebuilt it as that was when i installed the adjustable fpr. also say a...

for some reason you can only notice it startin to hold back in 3rd and 4th?? dont no if that means anything??

thanks for all your help guys, i thought it was gona be a straight forward swap with nothing else to do, do the rev3 injectors run at a different pressure? got a adjustable regulator today not sure what to set it at???

one of my mates had a drive of it and said it looses power at high revs due to under fueling?? at the mo i am still running rev1 ecu i have a link g1 ecu to be put on and set up yet. other mods are apexi avcr set at 1.1 bar, 1 bar actuator, decat, mongoose system, hks fcd,greddy intercooler, big bor...

im not sure if im in the rite topic but need some info, iv recentley put some rev3 fuel injectors in my rev1 tubby i got told i was under fueling and got recommened to put rev3 ones in. is there anything else i need to change? i.e do they run at a different pressure?? there doesnt seem to be any dif...
