guys hope you can help me, I am new to this whole thing of 300ZX. I bought one last weekend and I am already having problems. Today I drove the car and all was fine, then stoped at a petrol station to pump my tyres, after when I started the car it was not working well at all. It was shaking, it seems like it was working with less cilinders. Do you have any idea what could it be. I went for a drive and got it into high revs and it kind of opened up and it was all ok, but when it went back to low revs it went wrong again. Can you please give me any ideas
