i searched and found nothing..

1993 Twin Cam, with only an AEM SRI (did it before i got my intake, but who knows)..

if i keep my foot at a constant 10% throttle, the car chugs for about two seconds, then goes normal..

she pulls hard any other time, and idles fine..

but when i give it only a tiny bit of gas, she hesitates and bogs a little..

what can it be, timing..?

how do i check that..?

 

dirty maf?

 

not sure, seemed clean when i installed my intake..

i did notice when looking online that Z32 MAFs had a mesh screen..

should mine have one..?

 

no, there is no screen on the s13 mafs. grab some brake cleaner.....not carb cleaner. The brake cleaner leaves no residue behind when it dries. Get the brake cleaner and spray the little elements inside the top part of the maf. Be careful not to get to close with the can, the pressure can damage the elements. Just generally clean up the maf, make sure its dry, reinstall it. Disconnect the battery and step on brake for approx. 30 seconds. This will ensure that all power and mem is erased. This will ensure that you start from square one on the computer. Go out and put about 40-50 miles on the car and see if it goes away. Good luck

Yuo can also use high Percentage alcohol (90%) to clean it, but brake cleaner has more cleaning agents and preasure. Check vacum lines, seals hoses etc.
