  1. Hello all, I'm struggling with a recently acquired, stock 78 280Z running very rich. As in 13-15 mpg combined, and all plugs are getting carbon fouled to the point one or more start misfiring completely. I changed the previous owners BPR6ES with fresh BPR5ES plugs, but after around 1000 miles I could again hear the 5 cylinder "brrt-brrt-brrt" and soon after the 4 cylinder "cho-cho-cho" ? I've been troubleshooting using my multimeter and the 1980 EFI bible, it's all well within specs except for the test 1- (3b) - Air flow meter resistance #2 (ECU pins #7 and #8). It gave a reading of
  2. Hey everyone, I have been a long time lurker on many forums and I have decided to post some questions because I am at the point where I believe I need guidance on next steps and want to make the right decision. The car I am working on is a 78 280z California Car. It is not my car, it is my parents car that I bought them as a gift 10 years ago. It has been a long time since I have driven the car so I don’t recall its characteristics but it always had a presence of fuel smell in the exhaust. The car was parked because the fuel smell and rough driving started getting worse. The car then sat for a
  3. Hi all: I searched here for the answer, and I Googled a bit for a source. But no luck so far, other than Ebay, which has connectors that don't look the same as mine. I noticed on my '77 (that I just bought) that the AFM connector does not seem to have any retaining means in the AFM. If I unbolt the AFM, the connector falls out as soon as I move it. I'm concerned the connector will fall out while driving. Is there a source for a replacement connector, aside from getting an entire harness? I can't even tell what is supposed to retain it. But I assume this is not an uncommon issue
  4. Hey guys (and gals), I'm the new proud owner of a 1977 280z. I don't know a ton about cars, but I'm mechanically handy and I have downloaded and read through the FSM and the FIB for the car. When I first got the car, it had been sitting for a year and wouldn't run at all. After replacing the fuel pump, it starts and runs, but very very rich. It fouls all 6 spark plugs in short order and idles very rough, occasionally dying. I first suspected the CSV, so I disconnected it with no success, though the engine still started fine so I have left it disconncted. Then I pulled the CSV to see if it was
  5. Hello everyone I am needing a 1982 280zx turbo AFM, wire loom and ecu. I have a 1975 280z that has an '82 turbo transplant. Problem is that the air to fuel ratio gets lean at higher rpm's. Which is why my pistons are melting and broken:tapemouth. So I figure this may be the best solution, unless someone here has a better idea with what I have to work with. Note, I have not look hard into mega squirt yet. but lets start here first. Thanks. Big Al.
  6. Hi new to the forum, I have a 77 280z 4sp sat for 15 years, worked on it every few years because of fuel problem. getting divorced and need the car, had choice keep wife or car chose my z. Initially removed tank had it boiled and lined car still didn't run. Now I have discovered fuel tank is blocked internally, so I installed a new outflow line threw drain plug of tank, blocked existing outflow line. Installed new fuel pump,, changed plugs filter, car started right up and ran rough but ran. Problem is now that after driving a couple miles the car hesitates, backfires some when driving and the
