... and I got an EGR and TPS malfunction. However, I can't link that to the symptoms. When cold, my 87 NA idles unstable but ONLY after I start driving. After its been warmed up, it runs fine. After I've been driving for a while the idle speed goes up to about 1200 RPM. Also, the check engine light comes on only after I drive the car at about 50 mph or more.

I'd like to see what you guys think before I pay for a full inspection. In the meantime, I'll look around for parts (OEM, as Im presuming there are no aftermarket ones). Help appreciated.
