What the problem with my 2005 suzuki verona stalling while driving

How ,get it serviced, like the operators guide states//
all cars for 100 years do that."gross misfire and stall"
all.. why?
all not serviced do that. "like bad spark plugs"
get a tune up
or scan with any scan tool and bingo DTCs ,report them.
if the 2L engine, see those cops.
are ends all carbon arc damaged.?

let me guess,not one tuneup last decade?
ran it to ground.

in truth , misfire has over 50 causes
guessing is silly ,no?
even a dead alternator ,will stall car
or overheated
or bad fuel
or clogged filters.
egr stuck open
or ISC stuck closed
and
and
and...end.

It could be the fuel pump or a sensor.
The easiest way - and the cheapest, really - take it to a workshop for a diagnostic check. Let them identify the fault.

If you yourself begin changing sensors etc .. in the hope that you'll cure the problem, it's more than likely you'll buy and fit parts that aren't needed.
