When i have the throttle open half way it takes off normally, if i open it all the way up it bogs out. Can anyone help me out?

 

Check your IACV. There may be some carbon build-up inside your throttle body.

 

Or it could be misfire. whens the last time you changed your plugs and wires?

 

Just changed the plugs about an hour ago and its still bogging. As for the iacv im going to check it. i will get back to you. Thanks

 

well if its bogging at full throttle, it kinda sounds like a fuel problem, your sucking in the air but not getting enough fuel......maybe check the fuel filter to see if its flowing ok....im going to have to ponder on this one

 

could be a clogged fuel injector or maybe it needs a valve adjustment

 

If at all possible, check the voltage at the throttle sensor, should be around .6v at closed throttle and around 4.6v at WOT. It does sound a lot like a fuel problem, though. If for the throttle sensor voltage stays low, it oculd effect the amount of pulse width being commanded by the ecu.

 

map sensor also would explain why its boggin at WOT check your map

 

make sure your car is not misfiring!

 

thats what i thought it could be misfire. did you change the wires when you changed the plugs? it could also be the ignition coil

 

Maybe it's because it's a D15? Incurably slow, sorry to burst your bubble.

 

You wasted your first post dude....don't be a gayfer...this kid is asking for help and you wanna clown on the motor???? tsk tsk tsk

 

Wow not a good way to get on HT with that. D15 is slow. Pls.
You need to check your TPS because this is what happened when my TPS went. You have to get a Meter and test what the voltage is @ Idle and @ WOT.

 

I have a D15, who gives a flying **** what motor he has.

When my cam timing was off I would bog up hills when I gave it more than 1/2 gas.

 

yeah, you might want to make sure your timing didn't just a tooth......that would be a good place to start......

 

I finally have a day off tomorrow so I'm going to try he suggestions. I have a friend who has a spare fuel pump if that the problem. The wires are arching a bit so that's another thing I'm going to have to get in the morning. I appreciate every ones input a lot. thanks and I will get back to everyone on Thursday.

 

oh yeah and buy the way i got a ls im building and a turbo kit if that's an ok motor for ya..

 

So your going to do a LS on boost?

 

yeah but that's not for a little while. I have bills to pay like everyone else haha. gotta make sure the d15 is gunna be able to be my daily for a little longer. by the way my buddy and me checked the duel filter and the ws some build up but still some bogg but help.. thanks
