So when i was giving my Z gas is seemed to lag.I could feel the engine hesitating or something.

I watched this video and he mentioned something similar at 1.38

My N/A auto lags for a second before it takes off but you a 5 spd and should be instant. Unless you have a lost of power which could be a vacuum leak or need to do some cleaning to some of certain parts to stop the hesitation.

check your compression, the same thing happened on my NA and i has little to no compression on my 6th cylinder, make sure your compression is AL LEAST above 140

follow these links. i was having these same issues when i got mt Z. i ran some sea foam, cleaned the throtttle bodies, replaced the air and fuel filter(make sure your lines are tight). now she runs smooth. do a compression check and check for your injectors.
