I'm from Brazil, and have a Volkswagen POINTER GTI 2000 but this engine uses eletronic injection FORD EEC-IV...(EFI, not SEFI) with 4 injectors. When i turn on the engine and step accelerator (move the thortle) engine respond immediately.... and i repet this step , and no problem After 1 or 2 minutes , when i step the accelerator, engine not respond immediately ... I turn off the engine, turn on again, and accelerate the engine, it respond immediately so the delay to defect now is less, after 30 seconds , the problem return and engine not respond when i accelerate. (move the thortle) My EEC-IV use a MAP (manifold absolute pressure)... I check (run diagnostics) , and EEC return code 18 "18 = Check base timing & advance function - Timing Tests / Ignition TACH signal erratic " Some times, when i connect cable to diagnose the EEC, after ENGINE ID, engine down... So i replace TFI, and MAP, but no results, problem persists.... Can be HALL SENSOR ? I would appreciate its help...
