65mm TB = throttle hang?

[Barrett01]

I just installed my 65mm TB on the 3L.

For some reason, the throttle likes to hang. The speed bleed on the plate was epoxied shut, so I dont think the TB is leaking because when I coax the revs down (going slow) and then stop it will idle a bit high (~900) but will idle fine. It has an SVT tps. does the TPS have to be re-programmed to the values the 65mm is putting out? Sometimes the revs will rise and hang ~2000rpm higher than I let off at.

Please help.

be carefull with the tps's, some of them rotate in the opposite direction than ours, they are not necissarily interchangeable

All the how-to's that I have read have said to use the SVTC tps.

This is interesting to me since I just picked up a 65mm tb off of eBay.

As long as you used the TPS that came on it, or an SVT TPS, you are ok.

As far as the throttle hang...it could be a number of things. Did you tighten the spring on the TB. What i mean is does the throttle plate "snap shut" when you let off the throttle? You may have to turn the spring one more time to make it tight.

[JustinS]

I would just try wrapping the spring around one more time to see if that helps get it shut even quicker.

Ya replace the TPS. Maybe the one you got is bad.

Where did you get the TB? What i mean is who made it for you/did you make it for yourself? Did they use the SVT throttle plate?

IMO the TPS is bad.. I guess I solved my own problem

I am impressed with your deductive reasoning there Stealthy, just had a quick glance in the alldata, and its summation of a p0122 was "replace the TPS"

Hope you sort this one out and the car gets back in tip top condition.

You need to swap out the TPS from YOUR SVT TB Josh

[jrak123]

what happened to the TPS that was on the SVT TB that was sent to you? was it on there? Reason being is a I send icefury my SVT tb with the TPS on there, cuz he said he sent you the TB he had w/ the TPS on there also. So I don't have one, I'll go buy one I suppose.

That is the TPS that is on the there now.(the one that came with his TB) The 65mm TB I had for you didn't have a TPS on it. So just swapp yours out with the one I sent

[jrak123]

Yeah, that is the one that came with the SVT TB
