New suzuki guy here - first off want to thank fixkick for all the online material -it's been incredibly helpful learning this suzuki stuff!
I took a 95 Sidekick 1.6 16V engine (OBD1), rebuilt it from info on this site, and istalled it into an 87 Samurai.
When cold, it's idling above 2k RPM for over 10minutes when cold out (0 deg) and then eventually drops to 800, and then it runs great. When ambient is 70deg, it isn't much faster to idle stabilize. So far I've:
-Verified NO CEL or codes (only 12)
-Verified timing (~5deg BTDC)
-Verified ECT sensor resistance/voltages
-Verified IAT sensor resistance/voltages
-Verified ISC resistance
-Pull fuel pressure regulator vacuum line and idle changes
Then I checked the ISC air hose pinch test. When motor is cold and I pinch the hose or disconnect the connector, idle drops. When motor is warm - pinching the hose or removing the connector doesnt change idle!
So I've began looking for major air leaks and cant find anything using carb cleaner. Also - the only hose that changes idle at all when pinched is the hose to the evap purge solenoid. (is this correct or also a problem?)
What next? Please help!
