I have just re-engined a '01 Four Winns H210 (5.7 GSI). Engine starts and runs fine.....when shunted for timing setting...rpm shows 600 ish and smooth @ 8 BTDC...whith shunt removed, idle drops and engine runs rough, hunts..At 1000 rpm I inserted the shunt again and engine picked up to 1250 rpm. I think it may be stuck in module mode? Any ideas on what to check first?
OK so I have read some more. Correct me if I am wrong, but shunting the DLC should put me INTO module mode there by bypassing the ECM...right??? Assuming this, when I remove the jumper the engine idles down, too slow and begins to run rough, hunt....
Could the knock sensor cause this? It was pretty nasty when I took it out of the old block...
