i have a ca with a sr20 turbo and i think a ca airflow sensor, i can push my car up to a bout 10lb and it will be fine but as soon as i go full throttle it starts jerking and popping and sounds like it is mis firing, sometimes it doesnt do it at all though and it normally doesnt happen in 1st or second just in 3 4 5 gears even at 8 lb i can get it to do this thing when im wot. does anyone know what the problem is, and i do have plenty of fuel going to the engine my a/f gauge is plenty rich, unless could i be running to rich? or not enough spark or something?

Im almost sure your running out of your maf capabilities .. the s20 turbo outflow the poor litlle CA maf.. you need a new maf , ecu retune or SAFC

thats what i was thinking because i have read my airflow get to 4.85v one time, but never checked it out when it was cutting though but yeah i have the e-manage so i just prolly need a z-32 maf correct? is that the best way to go with the ca and a e-manage system
