the cause for bad idle cold are many.... (trouble codes?, and stuck open EGR are first. )
my previous comments were only for checking that the air source was good. at start, and cold idle. i check it and if ok, move on...
300 is random misfire. 340 is bad CMP and for sure causes 300s CMP is the hall sensor in the base of the dizzy, it creates all spark and timed injections.
DTCs, and bad electrical power 12v to the EFI system (dizzy too) are #1 always.... no DC power, no joy.
1715 is PRNDL tranny switch failure ( is this A/T car a 3sp or 4sp?) "sets for cranking in gear, i think"

1: low compression, below 170psi?
2: spark ( quality and timing)
3: fueling. (bad air supply can in fact cause bad fueling or air leaks, causing lean,
yes, 340 is root. (totally unacceptable this...)
the fuel rail port of fuel filter port are both good for fuel pressure.
the harbor fright stores here (USA) are the cheapest, fuel gauge has the Suzuki hose inside for the filter. $15?
here is the rail fix. (many) all ways, to do it page ( i use the summit adapter by Autometer co.) this makes injector balance tests possible.

hints, the crank sensor CKP,if unplugged the car runs ok , but it makes 300s even possible , the CKP fine trims spark to allow 300s to be even possible.
the car runs off the CMP sensor. (cams sensor in dizzy) other cars this is not true. most cars die with CKP dead., not the G16B
the CKP was added in 1996, (missing in 1995) it's the OBD2 magic.
on all new VIT/Kick Tracker G16 engines, it's best to be sure the cam timing belt are ok, and fresh. for max future life.
300s tell you the engine is misfiring randomly and so does the rough idle, shaking motor and felt in seat of pants.
more hints , dizzy timing
http://www.fixkick.com/IGN_timing/16v-procedure.html
ok, that 340 might be false,???,,, ive never tried it but, it might be possible to have the ECU report bad CMP timing if the cam belt slipped.
we already know it reports, dead CMP as 340s or 1 pulse missing every 8 , as 340s but consider this.?
what if it sees a gross error between the crank sensor and cam sensor. ??? what will it do then. "SLIPPED", my (really a contributor) sneak-a -peek test. or the acid test. is here... below.
on all G16s, im all over the crank pulley day one, that 17mm bolt, set at 94 ft/lbs, nothing more counts. just this, it kills good engines (crankshafts)
http://www.fixkick.com/t-belt/sneak-a-peek.html
if the Tbelt slipped all hope is lost, all words on this page, are tears in the rain.
here is a new car to barn (garage list)
1: 17mm crank bolt torque, (front) if at 50? set to 94, if below 50 worry, if even lower,,,cry. (many look and it wobbles....ouch)
2: sneak-a-peak. day. very very easy to do. (timed right ,shredded or both wrong)
(i really do warm to hot compression tests , x4 to see if engine has a future.... most do 180PSI WOT easy. wide open throttle or near.
3: EGR cleaned. (snaps shut now, easy) it only needs to close easy to make engine run well. (but does make exhaust valves last longer if at 100%)
4: ISC cleaned. (electric idle air valve)
5: a tune up (filter fuel is top check ) may be pressure test. to see if REG works.
6: as symptoms direct you. (and DTCs)
this list, is G16 focused.
Good luck to you, and it seems you have lots of spare parts, you are lucky and will win, and have a great car. to drive soon.
PS: the full fsm on YOUR engine, is here.

if any G16, is running bad. and not fiddled (molested) with yet, say , the PO spun the dizzy bad and forth. willy nilly?
the timing light, will do the sneak-a-peek test fastest of
all if the cam timing is way off, the belt has in fact slipped, a one minute test.
i here pro mechs, on newer cars,say, gee, my COP fitted, I-4 has no IGN timing at all "quote FSM", but does have a belt, and the 1 minute timing, check , does show you the belt did slip.
usually it retards big time!. (a big 1min clue that)
this works, like this, i drove for 5 years, then one day, lost all power, and misfires, , low rpm, etc..... bingo the 1minute test. (engine not touched yet)
good luck !
