Odd Throttle Cut out

[originalyunique95]

Howdy there, got a little issue. When I'm driving and hit a pretty good sized bump, my throttle will cut out for a second and then itll bog a bit and come back on. Im not sure what it is thats causing this, if theres anyone that knows or can help I'd much appreciate it!

Lol that could be anything. Check your sensor connections though; Sounds like some iffy wiring.

[originalyunique95]

alright, yeah im guessin it could be a bad ground.

Should pull out the fuel pump hat and take a gander in the tank, make sure everything is secure. Could be that when you hit a bump, the fuel splashes and the fuel pump only gets air. Does it do this on a full tank?

[originalyunique95]

Well its kinda full my floater is a lil off cuz its got a 255 walbro, so like the gauge will go down after awhile but its got around 150 miles on the tank.

I took the car to Auto Zone to check the codes and it said i have a knock sensor wire off. So would that be a loose wire that causes me too bog down when i hit bumps? And where would that sensor be?

[costa_rican13]

the knock sensor is between the middle of the intake manifold on the middle of the head. it is a major bish to get to due lack of cramped space. its a little smaller than a half dollar coin and is black with a bolt that goes through it. you cant miss it.

[originalyunique95]

Yeah your right its in there pretty tight, do i have to take of the manifold to get to it, because that seems like the only way to get to it. Or is there an easier way?

[costa_rican13]

No you can use a swivel socket, some extensions, and a ratchet.

[originalyunique95]

alright phew lol. thanks again man

[costa_rican13]

you might wanna try going in from the middle with those tools. other wise a super small wrench is your best friend plus icey hot.

[originalyunique95]

Ohh okay, and icey hot sounds like it'll come in handy lol
