Hi Everyone, I read many posts in the archives and lots of Google searches but I would love your advice on my specific case. I have a '78 unrestored 280Z that used to run like a charm and I'm not getting rough startup and probably heat problems? I am pretty noobish with mechanic (learning from 0) so bare with me. Symptoms: A vast majority of the time, the car will 'cough' a lot at startup and runs rough for about 5 to 10 seconds. I'm usually flooring it for a split second during ignition to avoid stalling and then gently rev til the engine runs smoother. I feel like the problem occurs more when the outside temperature is very hot (I live in SoCal), however my car is garaged and the problem also occurs in the morning. The car seems to run better warm and if I stop it after driving it for a couple mile and restart it in the next 10 minutes it will fire right away (like even faster than modern cars, I just push the starter and boom! When that happens I feel almost suspicious of how fast it starts). Finally, I had a problem 2 times. The car stalled after a few miles (usually hot day and driving a bit sporty). It stalls and doesn't turn back on. I had to push it to the side of the road and let it sit for 10-20 minutes before it'd start again. I changed sparks, fuel filter, ignition coil. Any advices appreciated. Stuff that I could check myself would be even better (keep in mind I'm a noob) Thanks a lot, M.
Hi everyone, I've had an issue with my Z for a while which hasn't really been a big deal but I figured I should probably figure out what it is in case it does turn into an issue that could be prevented. Every so often when I start my car, it idles rough (usually between 500-700rpm), shudders, and bogs down. It loses quite a bit of power until I drive it for a bit. After that, it's fine. It's happened with the engine hot and cold. Part of me wants to say that it seems to be the symptoms of the cold start injector firing when it doesn't need to, but I'm not sure. Any advice is appreciated. Thanks, Pac Man
