85 GN Engine readings. Opinions needed!

[maloneysforever]

I was hoping that I could get some opinions of the engine readings for my 1985 Grand National. I see pleanty of specs for 86/87 but aI think that it may be differant for a 85. My car is totally stock except for a K&N aif filter, flow master exhaust and hollowed out cat. It idles fine and runs on the road ok but I think think it should have more power. I took these reading with a OTC 4000E scanner. It seems that once I enter the data mode the idle goes up a little. I took these readings siting in my driveway after a 10 minute drive to warm it up.

O2 Voltage .38
O2 cross Counts 6
TPS .42
MAF 005
INT 128
BLM 150
LV8 028
IAC .38


Thanks in advance for your help and opinions

dont know hot airs but...ur BLM is too high, adding fuel for some reason, could be a vacuum leak somewhere. loss in power or just doesnt feel right is tough, remember its not an intercooled gn but it is also 23 years old so the engine could be tired... like valve springs and such. hth

try posting question here too, it is specific to hotair gn's:
