Sounds like the wrong temp sensor - different resistance will show different temp on your gauge.

I like in Arizona, United states. Happen to know the part number to that temp sensor? Or what it can be cross referenced with? Awesome replies, just need a day to check all this stuff out... Not to mention a dreaded battery draw. Again this Rb is in a 91 240sx coupe.

And if that were the case, what would the cure be?

Bump?

I've been searching to find this answer, yet I couldn't find anything that actually helped. Basically my Rb20 drives like crap 'till it warms up, I've been trying to find more info on this "cold start valve" but no avail. I have no idea what im looking for, nor do I even know what the problem is even if I were to find it. The car has to get around 50c degrees before it starts to run correctly. If the temp is anywhere before that, you step on the gas any little bit, it'll basically idle out. So to give you an idea of how to drive it, I have to keep the rpms at around 3k rpm just to start in first gear, then as soon as I get above 3k rpm itll run kinda normal in any gear (except I hate the idea of running my car that hard when its still cold.)
