I'm trying to locate a throttle body for a 94 metro. I've already purchased 2 of them and neither will bolt up to the manifold I have. The first one I picked up, I think was from a swift (after a little research) and looks more like a carb than a throttle body. The second one i picked up looks like this:![]() What I need is the throttle body that bolts up to this manifold: ![]() How do I know the difference when people say it'll fit a 94 (assuming I can't get a photo of the mounting surface)? Also, will other years TB's fit this manifold? And lastly, would anyone happen to have an extra one laying around, perhaps on a back shelf that they're dying to part with? This is driving me nuts, not to mention my wallet! Thanks Edited by magnus13, Apr 1 2011, 02:37 PM.

That's my problem. I seem to have found 3 different ones for a 94. I know which one I need, just not sure how to describe it or ask about it when I'm looking around online. Is what I have some special California or European or Japanese model? |

i believe you need the lower one in the pic?? if so my 96 looks the same get one off a newer body style. that way you are assured the right one. what is wrong with the factory one??? Edited by work car, Apr 1 2011, 02:59 PM.

That's correct. I need the one in the lower pict (with the square mounting surface instead of the rectangular). I'm working with an engine that I picked up and it didn't have a throttle body. I was told that it was a 94, and the engine ID number on the side seems to match that. The intake manifold on this has the square mounting surface on it, so I'm looking for a throttle body that'll match that. For all I know the dude that owned this before me could have swapped the manifold/TB to something else and this is what I'm left with. So work-car, what you're saying is the 96 TB that you have looks like it would bolt up to the square manifold? I guess what would be easier is to just get the right manifold for the engine. |

Another thought: How compatible are the intake manifolds/throttle bodies between the 89-93 models and a 94? I found a TB/manifold set that says it's an 89-93 (not exactly sure what car it came off of....trying to find that out). But just looking at the mounting surface/gasket, it looks like it'd probably bolt up. Just want to check with you all before I drop even more cash. BTW, thanks so much for all the help. It's really amazing how much knowledge is available out there about such a specific topic. |

You say you bought an engine without a TB. What are you putting it into? Does it have an engine in it already? If so you need to match the TB on that engine because that's what the car's wiring harness & ECU are set up for. If that means a TB like the top photo then switching the mani/tb is the way to go. If it means a TB like the bottom photo then switching mani/tb will not work. If you have, say a blown engine in the car now you could just use the mani/tb from it. If you have a shell with no engine you need to match to the wiring harness. I think we need more info on what this engine is going into. Edited by duff_remle, Apr 1 2011, 07:22 PM.

Sorry, yhea, looking back at my posts, I can see a lot of vagueness. Here's the deal: I'm working on a custom buggy and the metro engine is perfect because of it's compact size. I picked up an engine/AT tranny without a throttle body. It's got an engine harness on it and I've got most of the critical pieces that connect to the engine and harness (i.e. ECU, sensors, coil, etc...). The thing that's keeping me from running it is the TB. I thought it'd be pretty simple to pick up a 94 TB bolt it on and go. Seems like it's a little more difficult than I thought. So I'm starting with the main engine/tranny. The intake manifold has the square TB mount to it rather than the rectangle. So I'm looking for the 94 TB with the square mount. My other option would be to get a TB/manifold combo and bolt that on. But how comparable are other years to the 94? If it comes to a bit of custom/re-wiring, I'm fine with that. Done that a number of other times. I've got quite a bit of flexibility because of what I'm doing with it. I just need to find the right direction to move. Thanks for all the help! |

i might be all wrong but is it possible that the rectangle type had iac (idle air control and a 4 wire tps) and the newer style has isc (idle speed control with a 3 wire tps) ? just different ways of increasing idle under load put on by the ac or alternator loads? the rectangle maybe to accommodate the air passages from the iac. just a guess..... ive only had a geo for a few weeks and i cant get it running right but i did sleep at a holiday in last night!

You might have better success finding a manifold for the tb you have other than finding a tb for the manifold. |

Ultimately you have to have the correct tb for your ECU and wiring harness. In 94 both the top and bottom pictured tb's were used. (I have 2 94's, one with each style of tb pictured). So it is very possible that your 94 engine came with the bottom pic'd tb from the factory. The tb in the bottom pic was used on some 94 3 cyls and all 3 cyl models from 95 up. So work car is correct, you could get one from any 95 and up 3 cyl. If you're worried the mani (and required tb) dont match your ecu/wiring harness then you need to go off the ecu to figure out which tb (and thus mani) you need. I guess you could go off the numbers on the ecu but I'd probably just try to figure out which would match the wiring harness. The bottom pic's tb has an idle speed control motor hanging off the back of it. The top pic's tb does not. So if your wiring harness has a plug for an idle speed control motor then you need the tb in the bottom pic. Here's a pic of the idle speed control motor. If your wiring harness has a connector that'll fit the plug in the black box of this pic (the other style tb wont have any plug even close to this) then you need the tb in the bottom pic of post #1. Hope this is decipherable and helps. Edited by duff_remle, Apr 2 2011, 10:51 PM.

I have a 95 metro that has an intake manifold similar to the top photo, same problem no TB unit. also all the plugs for the wiring harness have been cut, just wondering if 95's came with this manifold also? Thanks. |
