I just put a new ls (4mm over) throttle body on my b16a. I'm trying to calibrate the tps but i'm getting wacky readings. Car is running pig rich shitting fuel everywhere, as the wideband will concur.

I then loosened the tps and moved it back and forth and it made no difference? ( yes its on correctly) What could be the problem ?

 

you sure you didnt swap the map sensor and tps plugs by accident?

 

yes

 

I had the same problem you have. My TB gasket was no good, there was a vacuum leak to the map sensor so it was reading low vacuum (ran rich). Went to the dealership and bought a new one for like 5 bucks. Works perfectly now.

Yup! Happened to me as well. Put your ear up to your tb at idle and see if you hear a leak. Go get yourself a new gasket or some gasket paper, and that should fix it. I was running so rich it smoked out my friends entire block, and smelled like burning seeweed.

 

I used a new tb gasket, as well as tps gasket and yes i put it in correctly. Idle is not high though, like i thought it woudl be if i had a leak ?

 

Is there a gasket for the map on these things ?

There should be o-ring not gasket
TPS has gasket

 

**** i don thave an oring

could that be it ?

 

 

did you trim the gasket and match the manifold for the new throttle body?

 

match the manifold?

No i didnt trim gasket, its only off a few mm's here and there. Can hardly imagine that would make it be pouring gas out

 

well to be sure i trimmed all around the gasket and matched it to manifold opening. Without the charge pipe on its idling at 3 grand, and still rich. If i hold my finger over the big hole right before the plate it idles down good ?

 

This **** is BANANAS &gt;:0

Lovely how an hour project turns into 3 days

 

just listen to what people said, get a new gasket again, use some silicone sealer if you have to an tq down to correct numbers...

 

how would a new gasket be any differnet from the new one i put on yesterday?

 

what gasket did you use? did you get a throttle body from an automatic?

 

I cant be certain whether it was auto or manual.

Some sort of vaccuum hole in the tb right before butterfuly on intake side.

Yea guess your right, my b16a tb had the same holes. I dont think any of its bad though cause it ran fine yesterday till i decided to **** with it.

 

take the gasket and TB off, hold the gasket on the backside of the TB, i bet you find where the leak is.............

on another note, is it the upper hole in the tb or the lower hole?

sounds like it could be the Fast Idle thermo valve.

yeah do you even have the IACV hooked up?? that will most definitely affect idle...

and are you just leaving that hole open to the air? lol.

 

WTF lol! Are you bypassing iacv or have you just removed it completely
