Re: 93 prelude high idle problem
quick what to do list
usually these things fix bad idle or/and hesitations:
- new spark plugs & wires
- new distributor cap & rotor
- new air/fuel filters
- clean injectors/iacv/egr/fitv
- 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 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
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.
