Hi all, spent time on Sunday in my friends garage as we are trying to get the S14a running.
Some months ago it cut out on a motorway and had to be recovered. Car has covered 60 miles that day and was running well, at about 65mph lost all power, wouldn't rev and cut out if clutch pressed.
Yesterday we did the following tests :
All fluid levels fine.
Compression test good on all 4.
Fuel checked ok.
Sparks ok. Plugs are black but were anyway as car used to run a little rich.
Run with lambda disconnect, still won't idle properly or rev.
ALso disconnected AFM, same as above.
Car runs, very very rich, won't idle or rev, loads of black smoke for unburnt fuel out of the exhaust.
Racelogic TC is turned off.
Tried a fault code reader, ECU not showing any.
Apexi AVCR and SAFC2 (left to monitor knock only) showing no knock or unexpected results, injector % as expected on idle, 1 to 2 %
ECU is original with HDev board added and custom map.
What would you try next, this is stumping us?
Cheers.
P.S. I have a video of it running I can upload if that is possible.
