Hi all, it’s a FI diagnosis I’m after, please help.
1973 1.7L standard FI system. When hot after a long run, I have a really rubbish tick-over and car wants to stall. I thought it would be MPS as mine has already been opened by a PO, but it reads 94 ohms on the outer coils and 398ohms on the inner terminals. It seems to hold vacuum too (only tried sucking on it, don’t have a gauge) so can I rule that out?? I really want some further checks to do as it’s running so rich I can see smoke at a hot idle and it’s difficult getting it to pull away without bogging down (only when hot - it’s great when cold!!) So it’s a hot only problem I’m having. Thanks for any help. |
