I purchased a Professional Products Plentium and TB today. The install was smooth only took about 30 minutes, but after I got it installed, I ran into a small problem. If I try to take off easy, when I barely push the gas pedal, it sticks just a very little bit. It doesnt take much to push past it, but if I actually try to take off easy I usually rev a bit. I tried to lube the cable under the dash and under the hood, and I lubed the TB spring and arm. I don't know what else to do. Anyone had this problem and know a fix?

Thanks,
J

I am not surprized you are having problems with the PP TB and plenum. Made in China garbage if you ask me.
You get what you pay for.
Have you ever owned a PP Throttle Body or Plenum??

I have them both installed on my car right now and have had zero problems. Installation was a breeze. The throttle movement is smooth and effortless.

The thing that ticks me off the most is that people here are soo quick to jump on bandwagons. If a part is not made by Steeda, MM or Accufab it is automatically classified as junk.

I bought both PP parts for about the price of 1 Accufab TB. The performance difference between the different TB/Plenums is negligable(+/- 1-2hp).

For the Money, the PP parts are a good value.

I had the reverse problem. I went through 2 ea. PP throttle bodies (both like to stick open) before buying an Accufab. I'm not saying they're all junk. I just had no good luck with them on my 86.

I guess that Plentium = Plenum. NOW it makes sense. :D

Thank you for your first hand experience. That is the kind of info that is usefull.

Maybe the design for the 4.6mod is better than the '86, becuase I have had ZERO problems.
 
When I was researching the Accufab, I read something about vacuum lock. It's the case where there's not enough air flow at idle so when you step on the throttle, the vacuum goes up and feels like it's holding the throttle plate. The fix on the Accufabs was the set screw that will open up the throttle just a hair if your turn the set screw in. I can't remember the details or the thread. I don't even know if it applies to the PP brand. But it's something to look into before giving up.

I think this is something that applies to all throttle bodies.

That is definitely a distinct possibility. What's true for one of a manufacturer's design is not necessarily true of them all.

Just an observation, do you like US made products better. But you have a WRX on your avatar. I've seen threads with Accufab problems also. Oh well, I had the PP on my 03 when I owned it, it worked well. Do a search, I think you will find your answer.
 
I have the same PP TB and plenum. Works find with me. Make sure the two cables are snug and in the right places. I've had no problems at all, quite a nice product too, they give you parts for both 96-98 and 99+ gt's, cuz the vacuum nozzles are diff sizes for diff years.

Yes,actualy I have had first hand experience with the PP TB.
Within two years I have been through three different brand
throttle bodys.I have a C&L trueflow plenum on my car.
First I had a PP TB and then a Mac TB.Both TB's liked to
stick and hang at 2100 rpm's no matter how many times
I adjusted the throttle cable.Currently I have a BBK TB
and C&L Plenum and it works perfectly fine for me.
Most products made in China are poor quality and junk.
In my opnion the Professional Products TB,Plenum,and
Typoon intake manifold belongs in a garbage can. :notnice:
 
Adjust the throttle plate set screw with an allen wrench while the car is idling until it doesn't stick anymore. Make small adjustments at a time. IAC will compensate, but if you have to adjust it too much your idle will hang a little before it drops to normal. Had the same problem with a BBK.
