Recently bought a 92 in excellent condition etc, just completed 30K service. However, having driven only a few other NSXs before buying this one, I cannot remember the idle. I can feel this car through the seat during idle, and it also feels a little rough from about 1-2000rpm (all in neutral). The car was completely checked by dealer before purchase and made no mention of idle. My previous experience is with CRX's (very smooth) and M3s also pretty smooth. Am I the only one that thinks this or is my car a bit rough, or is this just the way the NSX idles?
