throttle positioning sensor

I've always been fun Denny - now Im just sharing it with ya'll

 

We need to share good clean fun. Too many things and people are too serious.

By the way, my wife was born in Minn and she sounds like a hillbilly! Ya'll. Of course she was from south Minnesota.

 

I posted the following over in another thread....thought I would carry it over to this one too...it belongs here.

The symptoms you have described are symptoms of a bad TPS. It's normal manitenance, minni. Just replace it and those vacuum lines and the car should run fine. Just don't let anyone talk you into messing with anything else on that CCCarb and you will be good to go. You have a nice wagon....fix it and enjoy it.

 

saw that one too. thanks, Im having a hard time being patient with her.

 

And she's having a hard time trying to run for you with a bad TPS and cracked vacuum lines.

 

so how much into the carb do I need to get to swap out the TPS? Can I just open it up and swap it and close her back up or is the surgery more detailed than that?

 

Don't know. I have never replaced one and I no longer have my factory manual for my old 88 Buick wagon which would be the same carb as yours. Sorry I can't be of more specific help. A factory shop manual would tell you how and then you could decide whether or not you want to tackle it. If you have someone else do it tell them you just want the TPS replaced and no other work on the carb. I can't imagine it being a real difficult job. As for the vacuum lines...just follow them one at a time and replace. That car has run for 23 years and by the looks of it it will likely run a lot longer if cared for.

 

Yeah, MN is just outside my house call range.

 

That is pretty much it in a nutshell but getting to it requires a bit of careful work. Here is the E4ME carb.



The TPS is the white plastic piece with the black harness connector on the right side of the carb in the picture. To get to it, you have to remove the top casting (air horn). One step involves the black metal lever directly above the TPS that has a rod on one end and a plunger on the other. You have to tap that roll pin back in order to free that lever. You'll also need to replace the air horn gasket after you pull it apart which usually involves some tedious scraping to get the old stuck gasket off the housings.

Here is an exploded view of the carb. You're basically removing everything above the gasket (2). The TPS sensor is (71).

 

Well, the time has come...Im selling Edna. I cant put any more into her with another vehicle needing work too. Letting her go cheap...listed in classifieds.
Unplugged the TPS - seemed to be giving a false reading...runs better. Still have the new one but thought it better not to mess with the carb at this point.
