Hi Im David, have you tried to clean the maf sensor ? also Another way to check MAF sensor output is to see what effect it is has on injector timing. Using an oscilloscope or multimeter that reads milliseconds, connect the test probe to any injector ground terminal (one injector terminal is the supply voltage and the other is the ground circuit to the computer that controls timing). Then look at the duration of the injector pulses at idle (or while cranking the engine if the engine won't start). Injector timing varies depending on the application, but if the mass airflow sensor is not producing a signal, injector timing will be about four times longer than normal (possibly making the fuel mixture too rich to start). You can also use millisecond readings to confirm fuel enrichment when the throttle is opened during acceleration, fuel leaning during light load cruising and injector shut-down during deceleration. Under light load cruise, for example, you should see about 2.5 to 2.8 Ms duration.
hows it going?
still at 6-9 g/s at idle?
what are your fuel trims?
need to know
do a load test on your battery ed
sorry wrong customer
sorry the only way Im allowed to communicate via phone is by offering you a premium service or by you selecting a phone call.
once you get a scan tool that can pull all the codes, we can go from there...thanks
