SR struggling to move???????????

[drzsnapj]

okay guys i need some help here, when i drive my 90 240sx SR it feels as if its bogging out (like a misfire, or something were it holding back) struggling to accelerate and move. but if i just rev it up under no load it revs perfect, no problems at all. i did clean my throttle body, and my MAF with MAF cleaner before this started to happen. any suggestions?

Thanks in advance.

Check for boost leaks with a DIY boost leak checker. It works wonders.

Also check your ground for the coilpacks and make sure its good.

Also check your vacuum lines to make sure they're not leaking.
