93 prelude with f22b swap idles from 2500 down to 1000
My prelude is idling really weird and I can’t seem to figure out why. And it has almost no power when driving. It feels very slow. It will rev all the way out but takes a minute to get higher in the toms and doesn’t “go”

- bleed the coolant
- new pcv
- adjust valves and ignition
- adjust idle from tb's screw and throttle cable
- check does sensors work properly: map, iat and tps (and try calibrating tps)
- then check wires, connectors and hoses, check grounds
- check ICM and ignition switch (there was 5th gen repair call for this also)
-check o2 sensors and vacuum/exhaust leaks (check all the seals - IM/header/TB gaskets, injector seals, maybe even buy valve cover gasket set...)
-check timing. after that: double check timing
-is engine light on? check error/engine light codes
-clogged cat might you give some trouble as well (usually when driving) - check cats condition
if none of these seem to work - do compression and leak tests
and if you have chipped ecu and youre running it just with basemap, it might not work as well than properly tuned one
those are basic maintenance as well.
