car bogging under light throttle and throwing P0102 code my 99 Z28 is throwing P0102 (mass airflow input voltage low) or something like that my car will run fine then it will bogg realy hard under light throttle,also surging at idle, also very rich when this happens,i push in the clutch and rev it, its fine after that i dont understand could the descreening of the mass airflow meter or long tube headers and no tune have something to do with this, this is makin me very angry i need help finding out whats wrong

Sometimes a overly large cam will throw this code and requires you to change upper and lower MAP limits.
I would make sure that you have the MAF plugged in properly and that no wires are broken or that none of the plug pins got bent out of alignment. Also check the MAF resistor wires and make sure you didn't break one. Also make sure they are free of any dirt or oil. They are very sensitive. I clean mine with a Q-tip soaked in alcohol.
If that doesn't help, then find someone that you can swap MAFs with just as a test.
keep us posted.
Good luck!

yes a little most of the time its fine but occasionaly when under load at low RPM it starts to bogg and run rich when i push in the cluth and rev its fine after that does this sound like problems with the mass air flow meter its pullin P0102 (mass airflow input voltage low)

all the MAF meter wires and plugs are fine and in good shape,as are all pins inside the connector, just cleaned my maf meter with Q-tip and alcohol the small wires inside were dirty and noticed small improvement but not fixed by a long shot i dont currently have any friends with a car simular to mine so cant try the swap right now, Car has more than 100K miles on it do you think that it may just be time for a new MAF meter

Check the 20a fuse marked "sensor" in the fusebox closest to the front of the car. If it's blown, you've found your problem.

also could i just be in need of a tune from the long tubes cause it still dont seem like its running quite right that fuse was blown and i replaced it but its still not right could it be that the computor needs to be reset now to clear that code these problems started after i put the long tube headers and exaust
