  1. I have not. I am not a mechanic, so can you point me in the right direction to check for vacuum leaks? I am pretty sure I can check the fuel pressure by hooking a gauge into the nipple (don't know the proper term here) on the fuel rail. Is that correct? When I first got the car, it was stalling a lot. I took it to a mechanic I trusted. He ended up replacing all the fuel lines and vacuum lines. The rubber part that connects the AFM to the rest is also brand new and everything is tight. So, I don't think there are any leaks. The car also has a new fuel pump and filters. In any case,
  2. Hello! I have a 1977 280Z stock 5-speed manual transmition. The original AFM seemed like it was having some issues. The engine was running rich (you could smell it and I was getting horrible gas mileage), at idle the engine did not run steady/consistent (it revved up and down sort of like ooooOOOOooooOOOOoooo ... if that makes any sense ... and the tach would move with it below 1000 RPMs to slightly about 1000 RPMs), and, lastly, sometimes when going slow in third gear the car would hit a point where it would jerk until you either sped up or slowed down even further. I had a spare (used)
  3. Okay! Here is what I've noticed the past few times I've run the car. I don't know if this helps at all, but I thought I would add it into the mix. When I first put on the inline filter, I had filled up the tank to full. The car ran great for about an hour (on the highway and off). Then, as gas was used over time, I started to run into more and more trouble with the engine starting to run rough ... not continuously, but periodically. The more gas I used, the more I hit these stuttering and stammering spots (including a few times when I stalled out). Since my gas gauge is not working, I am
  4. Well, I replaced the inline fuel filter (the one between the tank and fuel pump) and this is what I found (and after only about a half tank of gas!): I would say I definitely need to clean the gas tank.
  5. Well, I think we know what the stuttering/stalling issue is with the engine: I replaced the inline fuel filter (between the tank and fuel pump) after only running about a half tank of gas. I definitely need to clean out the tank.
  6. I have. None of them in my area (Roanoke, VA) do the work any longer. I either will have to do the work myself, send the tank out to a place that still does it, or get a new tank. I think I will opt for the first option. There seems to be plenty of tutorials on how to do this.
  7. Hello steve edrington. Thanks for your help and advice. I appreciate it. Yep, I need to get the tank cleaned and sealed. It's next on my list (next to finding someone local that can/will do the work! They seem to be getting rarer ... at least in my area).
  8. Hi Seattlejester, I had mistyped earlier. The rust is not in the fuel filter in the engine compartment. That is a metal fuel filter and I cannot see what is in it. What I had meant was there is a small amount of rust flakes in the inline fuel filter that I installed between the gas tank and the fuel pump (the fuel pump is in the rear wheel well, as it should be). This inline fuel filter is of the clear, plastic type, so I can see what is in it. The spark plugs were replaced by a mechanic and the distributor checked. When the car is running, which is most of the time, it runs very s
  9. Sorry. That was my mistake. I meant FUEL FILTER not pump. The fuel pump is indeed in the rear wheel well.
  10. Hello SleeperZ. I already have performance tires for the 16" rims, so this is not an issue for me. The converters push the wheels/tires out quite a bit. This can cause issues with the tires possible rubbing on the fender when at a sharp turn. As importantly, it adds a vibration at certain speeds. I had this tested when I had the front end aligned and the mechanic said he could not get rid of the vibration (at certain speeds) as a result of the adapters.
  11. Hello again. Eventually I plan to get new wheels/rims for my 1977 280Z. The previous owner had put adapters on it to go to 5-lug rims. This is a bad idea. So, I want to remove the adapters and go to 4-lug rims. However, the tires are brand new (from when I bought they car) and are pretty nice - Yokohama Advan S.4 205/55r16 ... so I want to keep these tires. 16" rims look sweet on the car, too. From my research, it appears the original bolt pattern is 4x4.5 (114.3mm). When I look for new rims/wheels, is there anything I need to keep in mind other than the bolt pattern (and, of
  12. Thanks, seatlejester. I will try to respond to each point with what I know. While it has misfired once that I am aware of, the car stutters when it loses speed. It sounds and behaves like a car running out of fuel. The vehicle has had all new fuel lines installed, a new fuel pump (the one in the engine compartment), new injectors and new pig tails. So, I don't think it is anything in the actual lines (i.e. varnish in the lines). But there is a small amount if rust in the inline filter. Once the ground is dry I am going to swap out that filter for another one (I keep a s
  13. Good news! Internal and external turn signals are working! Bad news is I am not sure why, actually. After having the front end aligned, and the steering wheel adjusted (it was a custom wheel the previous owner had installed and was all crooked), the turn signals just started working again. The mechanic who had worked on the car previously (the one that did all the engine work) had also done something in that area because the horn had not been working. I am wondering if something, like a connector, had been lose (and maybe still is) and when they adjusted the steering wheel it knocked it back i
  14. Hello again! I thought I would start another thread about my '77 280Z and it's engine issues. A little background on me: I have done minor repairs such as replacing brakes, tuning an old carburetor, and even pulling a few pistons from an old '55 Plymouth. But I am pretty ignorant when it comes to the inner workings of a car, for the most part, though I am willing to learn. Now, a little about what's going on with the Z and what's been done thus far: When I first got the car a few months back, the car would not run at all. I could get it to start some of the time, but co
