You either have a bad ignition module or a
vacuum leak,intake manifold,PCV Hose,etc
that effects cyl #3

Ohm Checking is for the 1980's

Todays tool is an oscilloscope, you won't
have at home.

Also Smoke the intake and EVAP System
for leaks (EVAP Smoke Machine)

Maybe bad gas?


I doubt it.
Code 316 is a miss noted at startup, 303 is a miss on cylinder 3, 102 is a problem with the MAF sensor circuit and code 113 is a problem with the intake air temp sensor circuit.
The data the sensors are giving the computer are not in a normal range. The MAP sensor is reading too low and the air temp is too high.
I would check the sensors and wiring harness first to see if they are accurate.

2004 Saab 9-3 Aero. replaced fuel pump aprox four month ago ( @ Aprox 100,000 miles), the last two fuel fills I have smelt gasoline in and around car (no visable leaks). Check engine light came on 1 week...


While a fuel filter won't normally cause the check engine light, it could cause other errors that would trigger the error light to come on.

Since fuel filters are easy to change and not very expensive, I would change it and see would happens. But you might also want to run a pressure test on your fuel pump also.
