75 no way with 95HP and 2200 lbs body, up hill... sorry but sure hills vary , LOL !
but when you flog the engine at any time, does it run right like new , when hot. I'm presuming you had it when it ran good.
ok answer is yes, that tells me the fuel pressure is probably good. (well for hills it is)
good idle controls work.
sorry I was no clear, idle RPM's cold is governed by water temp. IAC device , a funny lump there under the throttle body,
idle cold is about 1500 and reduces gradually at 150f the IAC is dead closed, no air now, from it,, at 150f+ the smart ISC takes over.(+ecu smarts)
im not sure you have good gas, is it from Mexico? (i lived in S.Diego once (navy) and we bought gas there.(not wise)
id first try a bottle of chevron Techron , in the tank, I don't like additives, but this stuff is full of hot solvent benzine, and really can work as can the gas from Chveron. (sure most top sellers USA)
it can clean the injectors. if say, you get some bad fuel. it sure can't hurt.... as some lesser brands can .'
did you get all new spark parts ? plugs,wires ,rotor cap? yet,, get mag wires
mag wires from bosch or NKG,, will help any old suzuki ,it has very weak spark so.... mag wires help that greatly.
sounds like you have cold misfire. (seems to me)
it's not the 02, its off line cold.
spark is first. ]
dirty maf\
the maf is used even at 800 rpm
and the maf barely works that slow.
and needs to be cleaned say every 50k miles
as does ISC and EGR.
if the EGR hangs up, as the love to do when old.
they can do that common to a stop and engine stalls
or you are parking and not notice the hang up. (egr main rear of intake thunnel 4)
then on restart cold the dang thing leaks, and can not idle correctly.
to prove its not that.
on cold engine push it closed by hand (it has ring at the base,flex it, and it opens and pops closed.
then pull its vacuum line and golf Tee that hose.
now see if idle is ok cold, egr defeated for just a test, P0400 will trip. driven hot, defeated, no worry. for a day.
the cold idle is misfiring.
bad spark. (DO A FULL TUNEUP)
egr hangup, (it's off line cold but must not hang)
leaking injector(s)
even a bad FPR with too high fuel pressure,
ok good luck !
PS: evidence one can get.
if one removed all spark plugs to read them
do they all look the same, cream or light tan.
or one black? or one looking very odd some other way?
or a gap so wide one can toss a hat through it ?(gear head jocks, sorry)
