Ok so I fabed up a front mount for my 68 with a 88 tc motor. After the install it will sometimes sputter and want to die when you come to a stop, if you give it a little gas it picks back up and is smooth running at any rpm above 1000. It did not do this before at all with the top mount. I hooked up my trusty boost leak tester and there are no leeks and holds solid 15lbs while driving, on a side note after its been running a while and nice and warm it does not do it. My ? Is do you need to re adjust the tps or anything after installing a front mount. Its a stock motor stock ecu. Thanks for any help you can give me.
