What Is Wrong With My Rb20?

[sly32]

hey,

Ok so i have just put a new rb20 and r33 gearbox into my car, on first start up it started making a weird sound, that sound is now gone as im guessing it was just to do with no oil at top of the engine and the fact that the o-ring on injector 6 was completely screwed so it wasnt getting any fuel,

This engine was running sweet when i pulled it out of this other skyline btw,

so ive put it into my car, i got the ecu Dr Drift chipped, and also put in a Z32 afm that i also purchased off him,

My car is running ok, it runs on all 6 cylinders, and has a pop every now and then (too much fuel) and then if i rev it at all it floods the engine and drops a fair few cylinders and stops,

so ive been talking with dr drift and hes says the tune on the ECU should be close to perfect and should be able to drive on it, which i believe as my bro's car had the same chip and was sweet,

I sent dr drift how i have wired up the afm and he said i did it all right, (btw im waiting on response from him today as i just checked the afm for voltage and sent him the results) so i got from black wire to the white wire a voltage of .46V which i think its ment to b around .5V, so that seems ok,

I also did a ECU test, the code came up 55 so everything is checking out ok,

Do you guys think it may be a faulty afm? obviously me and dr drift will hopefully find out what it is this arvo, but i thought it wont hurt getting other opinions,

Thanks JV

id say its in the tune the afm seems to be ok if that reading and spec was accurate...

yeah i know thats what i was thinking but dr drift thinks the tune should be pretty close which i believe, i dno i guess i will go voer everything with him tomorrow and if nothing shows what it could b, then i will tow it to a dyno and get it tuned
