Could also be power or ground wires with dirty connections going to the EEC or the TFI.

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...

Any news on when we are returning to normal transmission. I'm actually starting to get too much work done due to the lack of email traffic.

Noticed that in the last days the digest editions have become very small, 4 to 6 messages per edition. Has anyone else noticed this? Used to be that there was a lot to read, now it's down to a couple of digests per day and only 4 to 6 messages per edition. ------------------------------ End of DIY_EFI Digest V4 #415 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
