my 300 jerks when first taking off

so when i take off my na 300zx jerks a bit then its alright after that and sometimes decides when to pick up in 2nd or 3rd gear. ive been told its the dirty fuel injector but does anyone know what else it could possibly be? like maybe the amount of air going in or something? thanks

 

Clean your AFM.

 

while your cleaning your afm. look at the plug for the AFM.

while your under the bonnet check a few other plugs as well.. PTU, CAS, coil pack connectors. etc.

*note* your checking for corrosion looks like white/green powder

 

Have the throttle bodies ever been cleaned?
Are both throttle bodies closing to make a perfect seal?
Have the throttle bodies ever been checked/verified to ensure they are in sync with each other?
I've done a How-To on this on 3ZC.

Name/type/size of spark plugs?
Gap verified with gauge prior to install?
Gap size?

 

as above

.....and check cas value
