Keep an open mind on cars this old , it's 22 years old !
ive never seen one, with just 1 problem, usually many,
for smog, like 3 or for issues.
On this car, if I liked it. id: first. do....
1: set all brakes, put 5speed in 5th gear, and torque the front crank pulley bolt 17mm (deep wall socket) to 94-ft/lbs. now. saving crank from destruction.
This is a TSB warning by SUZUKI. above. do that day1.
2: take off the ECU, and look for caps leaking. see hell pit here : http://www.fixkick.com/ECU/hell/html/image_6.html
3: check timing next, if off the cam timing bet slipped, or last mech "messed up", or never knew about the Freeze. or never learned cam timing 101.
the freeze is here for all years with freeze (all years)

4: a real tune up. called a 60k service POINT

spark and filters. matter.


does engine idle at 800 rpm hot>?
does engine reach and hold 180F hot, 180f is minimum, i run 195 in mine to save fuel.
CEL lamp out driving.
there are no scan tools for pre 96 suzuki/trackers. (cept by us hackers, http://www.fixkick.com/hacking/hacked/ad...acked.html)
having no scan tools makes diagnosis way harder, on all pre 96 cars in usa.
ECT read 300 ohms hot? (stop hot engine, pull connector , measure it? hot?)

try a new 02 sensor ? that dies about 100,000 miles and if dead, smog will never pass. (some can with a new cat installed, hiding the bad, it can)

ive not seen the chit yet, so above is general topic smog.
the chit may show only NOX failing, (EGR bad)

thanks for sharing !!!!!
