What are the average flow values (in grams per second) I should be looking for on my scanner for a 89 Camaro 305 TPI auto F code when at idle and higher RPM.
I have a Auto X Ray 240 scanner and the Maf reads 2240 G/S at idle and 6300 when driving at 53mph @ 1375 rpm. no error codes present.

Thanks
Gary

 

It sounds like the scaling of your software is off. 5-7 g/S is pretty common at idle.

 

Thanks Vader,
I have contacted the software supplier and you are spot on.
I am trying to find the cause of slight jerking of vehicle at 53 mph when cruising at light throttle. the static timing at that was set at 6 degrees tps 5.4v,block learn 120,integrator 127,knock sensor 38 counts. iac 117 steps.rpm1375,inj pulse 3.4ms,rich leanflag rich,maf(I believe 64.93), o2 cross counts 13,man air 114 degreesF,coolant 188degreesF.
two more scans at idle revealed knock sensor counts of 2 and 103 which seems abnormal to me so I today will set my scanner to knock scale an check the results.
Any thoughts would be appreciated.

Many thanks,

Gary.
