my 85 2.8 is throwing a code 34 and it stutters when you hit the go pedal like it bogs then goes and bogs and goes. is there a way to test my maf or to test my vacuum pressure to find out which it may be or could it be something else all together

 

ok i changed the maf an the code went away. the car seems to run better to. but it does still stutters not quite as bad. how do i check the vacuum. other than that i guess i need to look into ignition... any thoughts

 

have you done anything to clean your car? injector cleaner or seafoam treatment?

 

Code 34:
MAP sensor(voltage low)
MAF sensor

Check wires to MAF. make sure its plugged in, check all other wires close to it. other than that it may need a new one.

my other guess was plug wires but you already did that.
