What the heck is this thing on my moms 97 blazer?

[98tadriver]

97 blazer, 4.3 vortech v6. On the throttlebody blade, riveted to it, looks like some kind of plastic wedge shaped restrictor.. I would think that its blocking so much airflow! can i remove it w/o affecting how it runs? i would have to fill in the holes where the rivets used to be. at idle with the tb blade closed, its not in the way but anytime the tb blade is open, it gets in the way.

i outlined it in red

I would take it out....doesn't look necessary

[edpontiac91]

If it's running OK, then LEAVE IT ALONE. Everything that is put on there is either for emissions or driveablity. Taking it out might just allow TOO MUCH airflow for certain types of throttle positions, such as WOT. Ask someone at a Chevrolet Dealership before you do something that will screw up the idle or affect gas mileage. Just my :2cents:

Good point. maybe i will. if it was mine, i wouldve taken that out, descreened the MAF, CAI and did some other free mods. i dont wanna F' up my moms ride!

[bubba428]

yea thats a good point...might make the computer flip out

[NJSPEEDER]

computer won't flip out. we removed it on foff667's 98 S10 and put rivets in the holes. picked up a good bit of throttle response and some power doing it :)

It's your Mom's car, leave it the f alone!

[NJSPEEDER]

this is ron. telling him to leave it alone is like telling a 5year old not to eat the cookie you just handed him. may as well give him advice on how to do the mod right and get it over with. lol

[bubba428]

HAHA :rofl:

Hey, if the advice is coming from you, it just has to be good!

[wretched73]

Just pop the **** off and say you didnt do it :)

[Iroc-z86]

that isnt there on the 98+'s, my moms jimmy or dads s10 both have the 4.3, fully loaded and they dont have that plate thing. i dunno, the 97 and 98 are two different animals tho so who knows. its gm.

[98tadriver]

If bonzo can eat the cookie than ron can take that plate thingy out

humperdink?

i had a 96 S10, vortec, and i believe it had that on the throttle plate also. i wouldnt do it, you might screw something up worse. how do you think the fuel pump is bad.....is it rough starting, especially in the cold? mine did that. i went through several things, including a fuel pressure regulator, before i did the fuel pump itself.

My 98 Did, Im the guy That Timmy is speaking of. We removed it but it will create two holes in the TB that will need to be plugged, you can just put in two rivets & be done with it though.

I never really saw the point to it but it may just be a handicap because of the horrible injection systems which more than likely lean out the front cylinders. Bad design.

[JSPERFORMANCE]

It is there to make the part throttle transition smoother, when you remove it with a stock tune it can develop a part throttle lean stumble in some cases. If it is your mom's ride fix the problem and leave everything else alone.

[shane27]

if you dont know what it is just tear it out...nothing bad will happen

it doesnt start if its warm or cold until i pour a bit of gas in the TB. I turned the key on and pushed on the schrader valve and only a little bit of gas trickled out, instead of me getting getting sprayed. plus i didnt recall hearing the fuel pump turn on. i have a walbro fuel pump laying around i might be able to swap out so i dont have to spend 389.00 or whatever it was for a new fp

[EchoMirage]

sounds like a fuel pump. theyre known for going in these trucks. i bought an airtex pump from a local store, it was only around 200.

[98tadriver]

hehe i have a spare walbro 255 that im going to install soon. thatll be my xmas present for mom! that thing is going to run like a raped ape when im done with it. (i didnt say when i get done driving it.. so it will stay together)

i outlined it in red

All I see is excess weight!

Remove it.

If the car starts running rough.... add nitrous..... nitrous fixes everything :)

[98tadriver]

hahahahaha funny you say that because i still have my wet kit

[12secondv6]

hahahahaha funny you say that because i still have my wet kit

:shock: See..... she will be happy with it installed!

When she asks what the new red button is.... just tell her to floor it, hit the button and hold on for dear life :)
