Your girl just got a tune up for her 1994 Altima and it cost 330.00 that seems high to you Is that average?
1994 ford f150 transmission won't downshift from overdrive or any other gear or go in to passing gear at any speed Only when you stop will it shift down to low upshifts just fine?
I'm not sure what year or model of the car but if its somewhat new meaning about 1994. Then the computer does it and there is no adjustment. If you getting a rough or low idle it is probably time for a tune-up. If tune-up doesn't work you may have to replace idle control valve, up to 1989 there was an idle adjustment knob on throtle body for fine tunning.
