I need to identify the throttle body so that I can buy a replacement fuel injector.

 

I lost the pictures that I took and I'm 300 miles away from my car at the moment.

 

I think I have an EA82 SPI manifold and throttle body.  I could identify it if I could see it.

 

Can anyone point me to a photo gallery online, or provide a few pictures?  I can't find anything in a Google search (?!).

 

Thanks

Yes, its on an EA81 block... but I don't think that matters because EA81's never came with SPFI from the factory.

I sort of agree with you.  If I were at an auto parts store, how would I tell them the model and year?  1989 GL?

I was thinking that also. It does not look like anything I have seen.

looks like a Ford or GM unit to me.  Maybe Pinto?

 

Who the heck knows what is controlling it.

 

Sorry but we likely won't be much help with that setup.

Yep - identified as a Rochester TBI.  Seems to be from a GM truck.  I was able to locate a model number on it. 

Thanks to all.

Thanks to all.

Also looks a lot like a single barrel GM TBI from a 2.5L 4 banger. Something from a 'bout 1988. Or 4 cyl Chevy S10 truck perhaps?

Not from an ordinary 88-91 Chevy truck as those would be 2 BBL TBI bodies for both 6 cyl & V8.

Rochester model # is on vertical surface next to throttle linkage on TBIs. GearheadEFI forum might be able to help.

Can't tell you much more than that.

Looks more like a 84-86 2.5L Pontiac Fiero TBI unit:

http://www.ebay.com/...h1Zl6ch&vxp=mtr

 

Throttle position switch(TPS) looks to have been changed to a V6 or V8 one.

 

Pontiac Fiero injector on RA:

That black cube on top of the TBI to right of bore looks like a relay that isn't part of the the TBI. Like its just sitting there unmounted.
