I have this problem with my car when i am launching it at like 4-5 and it spins for a second then i full throttle it really fast, just punch it and it just bogs so bad like it dies as if i hit a fuel cut for a half second then it goes to normal and pulls out of it. i can also do it when im driving around 4-5k in 1st gear and just punch it all the way really fast and it just bogs. normal driving is okay everywhere else just in those two situations when i quickly punch it in 1st gear. does anyone know what it could be? would a bad map or tps sensor do this? glitch in tune? thanks.....

 

Is your car retuned from stock? Its probably the tune.

 

any poping and banging. if so is it coming from the intake or exhaust?

 

has been retuned but the tune that is on it now is just a revised version of the last one cuz i put new cams. the person who tuned my car looked at it and said he couldnt find anything that would cause it? im gonna switch ecus with my friend later to see if it still does it if it doenst then bingo.

and there is no poping at all its like when you hit fuel cut off.

 

I had the exact same thing happen to me when I switched ecus... For some reason it ended up being the tps wires, I switched the two outside ones, and bam it never did it again. But the reason I noticed was becuase the VAFC was reading 100 percent throttle at idle and when I floored it, It read 0 percent and absolutely nothing was changed... It was very crazy...

 

my wires have never changed for tps tho... its been same since stock motor..

tried it in other gears it will do it in 2nd and 3rd and probaly rest too but only at 4300ish rpm and i gotta punch throttle all the way down hella fast or it wont do it

oh yeah strange thing if it was the fuel map then i would think it would do it at full throttle at that rpm all the time but it only does it when i punch it starting from taht rpm not if i full throttle from lower rpm and pass through it.
