ran great until, it didnt,
but if the PO let the gas go bad, that gas can turn to varnish , and coat every thing from from tank to the end point , injectors
if can get worse, easy with fresh gas added all those cleaners in the gas, cleans off that varnish and may then clog the system later.
a delayed effect.
but i guess the car ran ok for 2 years, every day, or 4 times in 2 years.? how long did it drive ok , when you owned it.
if the car ran ok for 2 long years, every day , id think the above varnish issue is a none ISsue.
but needs to be said, on any long term parked car,
was the tank full for those years parked, (day 1 you got it) or 1/8th full?
the lower the tank level the more likely the fuel went bad.
2 years is about max on gas life, unless special additives are put in the fuel before storage. (STABIL)
The gas cap must be good, and it's vacuum breaker working, .
engine good. compression
sparks good, no scan codes P03xx of any kind driving it hot, and running the scan tool and for sure no pending codes, many codes take 3 driving cycles to set, that is why there is pending button to push in the scanner to see NOW, whats happening NOW,
btw all scan tools sold (real, not $15 code readers ) all work on this OBD2 car. (and all sensors can be scanned , at any time, even driving)
THINGS:
Fuel pressure at spec, it is.
FPR works good, it does.,
pump shut test passes, so pump is ok
leaving map , then injectors clogged.
one other possible is gross ,main induction air leaks.
from the rear of the mAF to the intake valves, there most not be any leaks there (just the ISC/bleed screw are allowed, idle controls only)
if you get a very bad air leak, this leak bypasses the MAF and now the MAF lies. called illegal un-metered air.
my 97 had this, the huge air pipe on top broke.
the PO, removed the 2 bolts securing the main air pipe mounts. this allowed it to bounce and broke the alum. mount clean off that huge pipe, and it sucked air like mad there(backside it was, nicely hidden..... ouch)
then the main air box was deleted, and he used this silly looking motorcycle air filter, and now the mAF bounces up and down and beat it to death.
a $1000 part at suzuki, not too smart wrecking any MAF like that. (IMO)
I call those events, can't win for losing,......
also seen the boot from left (face it) main air pipe, boot missing or damaged, and again sucking air like mad and maf cant do its job, even with a good maf, even new.
or just let that boot sit loose sucking air, not using the clamps there are designed.
my 04, that same boot was installed wrong and warped, to too it all apart and wow this huge gaping hole is there as the boot, folded and sucks air endlessly.
took a new boot to fix it, it was a wreck. (due to bad service)
this engine most not be allowed to suck in metered air. (maf)
