I'm going to preface this by saying I know pretty much nothing about cars...
I just got my 240z out of storage for the winter -and as I got her only a month before I stored her - I'm not entirely sure if this is a new problem or not.
We had a lot of trouble getting her to start up. One of my friends turned her up higher - my understanding is that this would make her idle higher and start easlier. She only idles at about 1krpm when I start her up. Here's the fun thing: if I'm downshifting for like a stop, she works just fine. If I kick her into neutral, her rpms stay just where they were when I took her out of gear... or even more fun, they go up. So if I'm sitting at a light, she might go up as high as 4krpm. If I turn her off and restart her, she's right back down to a normal idle.
I'm afraid to just turn her down a bit because I'm not convinced she'll still start up fine. Is there some larger underlying problem?
Any suggestions would be great. But I probably won't know what you mean unless you spell it out... Tnx!
