Hey guys, I've been having some drivability issues with my 1988 CRX Si. The car is for the most part, stock-ish drivetrain-wise, factory D16A6, etc. Prepped for SCCA's STS Solo class if you're familiar. Anyway lately I've been having wicked idle/misfire issues. It has a lot of trouble idling, and when it has a light load (ex: cruising on the freeway) it stumbles and misses like crazy. Weirdly though, it still sings at full throttle, I even ran an autocross/some track sessions with little issue, but on the entire (2+ hour...sigh...) drive home I had to drive with the speed in a sine wave pattern since it would miss if I tried to maintain speed. The OBD0 ECU is throwing a single, 3, 5, and 7 LED code which indicates pretty much every sensor (TPS, MAP, O2) but it seems unlikely that *all* of them failed simultaneously. I haven't had the opportunity to dig into it yet but I figured I'd ask in case someone's run into a similar issue. Really looking to get the car patched up in time for the SCCA TT Nationals at NCM in 2 weeks.
