is this the hesitation that can be cured (hopefully) by regrounding the engine bay?

the first rev up is a slow roll on. the second is a bit faster.

thank you,

What the engine does revving in neutral is pretty much irrelevant. The secondary injectors most likely weren't even being brought on because the load was too low. Go do that again actually driving the car hard. Better get someone else to hold the camera...

 

Do it...worst case scenario it'll be a cool video (I can already see the camera aimed at the sky when shifting )

BTW, do it in a safe place.

 

lol... thought the secondaries were rpm dependant... not load dependant.. also kinda hard when i'm still replacing the rear brake hardlines... no hydrolics = no stop = really bad

The secondaries come on when both rpm and load are above certain levels. It's possible to redline the engine in lower gears just on the primaries. Pointless though...

 

Yeah in my car you can rev it all the way up but when I take it out for a test . I does that but it wont get past it like yours did . It will climb very slow then all the sudden it will kick in then go back to hesitation . I have tried everything to

 

I went to my ECU and regrounded the grounds fixed the hesitation right up and it was easy as hell . I would suggest doing that seems to be the best fix
