Thinking I may have a vacuum leak since this is similar to the problems I had with my big block when a vacuum problem developed on my carb. Anyone able to help me out on what to do?

note, i've only noticed it at WOT, if that matters. I'm not at all familiar with this engine or the fuel injection system it's using... help would be appreciated.

 

ok, come on now. i know someone on here can help me. this question should be a breeze for someone.

hey what up, i got a std motor to, and ive also been trying to figure out the hesitation. when my does it, im flooring it, in sec. gear, and 30 or 35 i just feel it pulling then, but under 30-35 it i kinda feeling like its cuting up,but when i hit 35 it just goes, it feels like all the hesittion is gone. but of well im done with the std motor, when i was driving on the freeway today, i covered the whole freeway up with smoke, it was cool, i dont think any other cars could see. and now, the std motor is gone.

 

Here's your answer:

Buy an igniter and all your problems will dissappear.

 

i was thinking ignition and i THANK you more than you could imagine for that help. I'll be doing that tonight. The engine was rebuilt right before i bought the car, but within 6-12 months i'll be doing a built b20 swap. can't wait

thanks
