my car is 'choking' or 'bucking' at 4k+ RPM's i'm guessing it's a fuel problem. what do you guys think? could it be a vaccum leak causing it? (remmber doens't occur below 4k) i'm guessing it's something to do with the fuel because i remmber reading somewhere that the secondary injectors kick in at 3800.

 

Have you removed your 6port sleeves? Make sure your secondaries are plugged in.

 

Your TPS could be causing it but mostlikely it is your secondaries. Check to see if they are connected properly.

 

where is the tps? is it the screw on the top of the TB? yep sleeves are removed

 

I doubt its the TPS. That thing isnt even engaged above, say 30% throttle.

 

the TPS is on the front of the throttle body. Little black thing has three wires comming off of it and when you move the throttle linkage it has a little piston thing that moves out when the gas pedal is pressed.

 

ahhh i see. how would i adjust that if i needed too?

 

you would need a multimeter or one of those lights used to check it. But like drox said it is probably not the problem.

 

One of those lights..called LED's man..

hehe
