I just bought a Z the other week - a 1990 SWB NA from an ad on here (in case anyone saw it) - and I'm loving it, BUT I just wanted to ask about a couple of problems it seems to have. I should perhaps warn that I'm not too good with car things, not very good at all, in fact :/ I've got a mate who can bodge most stuff, but I'm loathe to let him lose on the Z. Anyway:
Firstly, sometimes the speedo needle shoots off the scale and stays there for a while (sometimes several minutes). There's a separate digital speedo installed too, and that then shows '0'. The rev counter works fine, though. Sometimes there's a chime when the speedo comes back again. I've not found any pattern to when it does this (my first car was a VW Polo, and that used to do something similar, but only after sustained 80+mph runs).
Secondly, sometimes when starting from cold (not ALWAYS, but maybe that's just the warm weather we're having) there's a big loss of power around 2krpm - say from 1.5-2.3k, maybe. Once it hits about 2.3k, the power kicks back in and everything's fine. But up to there, putting your foot down does practically nothing, and the exhaust sounds kind of chuggy ('chuggy' is probably the wrong word, but I can't think of a better one. It's smoother than a chug, but it's still sort of on-off-on-off).
Thirdly, more rarely, the steering sometimes goes heavy when it's doing this loss-of-power thing. I've not noticed it before last night, but that could just be because I'm not doing much steering at the right time (I usually leave work and get stuck in traffic for 10 mins or so). But yes, last night it definitely went heavy. This was from cold again, and it was labouring as well... and then the speedo went :S
I figure the steering thing is probably related to the loss of power, and I wondered if that in turn might be a faulty temperature sensor thing (I told you I know nothing). If it helps, I have noticed the climate control is not terribly good at heating :/
Any suggestions please anyone? I'm not *too* concerned about the speedo thing, although it's annoying, and potentially fine-earning since I live on a SPECs infested road But this big gap in power is annoying and pretty worrying.
