small idle problem after plenum/tb install

[imblown-ru]

my buddy just finished with the mac tb/plenum install, and everything is great except for the rpms hang at 1500 for a second when stopping at a light in nuetral. is this a tps issue or is something else causing this? thaanks for the help.

Probably just the tps. Get a voltmeter and check the voltage at the tps at idle. I think it should read like .99v or something like that, I dont remember the exact number.

check in the 5.0 magazine archives they did a 2 page right up on checking the tsp voltage and whats it supposed to read after certain installs...

I thought I've read on here someone saying that the area where the middle area where the blades on the TB meet the little bar that turns them actually leak around that area also. Just sealed it up and it worked fine.

I had the same issue after installing my Accufab 75mm tb and plenum... yeah my TPS broke the next day on the dyno lol.
