check for leaks into the intake by spraying carb cleaner along the edges of the inlet / throttlebody / sfi box etc etc.
Clean out the Idle control valve
see if this helps for now
cheers will look at that tommorow
i seems to hapen when the engine is under load when i first took it out first gear was ok but not as fast as it should be but now it wont pull at all
could also adjust the screw in the front of the AFM, dont forget to mark the initial setting position just incase it doesnt help things.
first thing I would do too, check for vacuum/air leaks
will a small air leak loose so much power ?
When you say built the engine have you run it in??
Or am i getting that wrong??
just built not a recon new lifters etc and put it into my mk2 cabbie got the block and head from different places
are you getting the ecu light flashing up ?
dont touch that fecking screw on the AFM !!
do you think the afm is fecked
I wouldnt jump to adjust the AFM 1st, eliminate other possibilities to begin with.
Its a tamperproof screw for a reason.
Check for air leaks in the intake piping as well as the rest of the intake
Have a look at the throttle switch, i had same problems with mine..
I had a similar problem (idleing high, when you push the accelerator the revs drop and it stalls)....was the air flow meter wire not plugged in properly. check that yours is working properly, and that the wire connecting to the loom is fine (maybe swap with someone else you know with a c20xe?).
