Default What is this thing? Need Help IDing Throttle Body (Pics)

I've been looking for a good quality S2 L67 TB to replace mine that has a stripped bolt and so far all i've found were really dirty TB'* with the brackets bent and springs not attached and other poor quality parts. So i see this one on ebay and it was advertised as a S2 L67 97-?? Throttle body, brand new supposably off a crate engine. Well i get back from my 5 days in Key West and sure enough it arrived. Brand new as described and as clean as can be. It'* almost perfect even. Few Problems though, wrong size MAF sensor hole, and a mysterious second vacuum hookup. Is this one of those pre 98 throttle bodies of for a different engine all together?

That is a 1996 TB... The 2nd port is for the 4T60-E Vac Modulator...

This TB also has the MAF Post... Where the newer ones do not..

According to the seller he will refund my money if i can "prove" it'* a 96. He claims it'* the same one that is on his 97 GTP and i really don't need this expensive of a paperweight sitting around. How can i "prove" this is a 96? Is it even possible that his 97 GTP runs the same one?

The 1997 GTP has 1 Vac Port as the 4T65-E Trans he has was not Vac Modulated..

If you are intending to use this on your 2002, you won't be able to use your 2002 MAF... As your car has a Postless MAF set up.... That TB has a POST down the middle...



Here is the list
Year Make Model Engine
1997 BUICK PARK AVENUE ULTRA V6 3.8L 231cid GAS FI * Engine VIN = 1
1997 BUICK RIVIERA V6 3.8L 231cid GAS FI * Engine VIN = 1
1997 OLDSMOBILE LSS V6 3.8L 231cid GAS FI * Engine VIN = 1
1997 PONTIAC BONNEVILLE SSE V6 3.8L 231cid GAS FI * Engine VIN = 1
1996 BUICK PARK AVENUE ULTRA V6 3.8L 231cid GAS FI * Engine VIN = 1
1996 BUICK RIVIERA V6 3.8L 231cid GAS FI * Engine VIN = 1
1996 OLDSMOBILE LSS V6 3.8L 231cid GAS FI * Engine VIN = 1
1996 PONTIAC BONNEVILLE SSE V6 3.8L 231cid GAS FI * Engine VIN = 1



I guarantee that in 97 the Lower port was not tapped in the TB... It was left undrilled and blank...

This TB was not used on a 1997 anything as it has the 2nd port for the 4T60-E... For all of the SC cars GM produced, that SC TB was last used in 1996 with double Vac ports

All of mine have been tapped and plugged from the factory.

The info that JR3800 posted is correct....However there are a couple (literally) that have the Vac. unplugged.

Is there a date code in the numbers stamped on the throttle body?

The numbers on my 96 L36 throttle body are-

RHA65 4 6726

245072 31

Bold digits are stamped not part of the casting.
