E-Force Throttle Body WTF?!?
All,
After much debate, I pulled the trigger on an E-Force 1580 kit for my '06 GT before Memorial Day. A few weeks later, I starting getting the dreaded 21XX error codes and my car would just shut off. It ran fine when it was cold, or when I was moving enough to get some air flow. But if I got stuck in traffic or when through a fast food drive-thru, it was over. Throttle position would stick, sometimes at idle, sometimes high. Then when I got on the accelerator pedal, the wrench light came on and the car went off.
When I took the first throttle body off, I saw what I believed to be evidence of the two resin / poly / whatever gears rubbing against each other. Specifically tooth material was displaced on the gear sides that faced each other. Possible gear binding?
I contacted Edelbrock and they were genuinely concerned. They expedited a new throttle body to me at the beginning of August, which I promptly installed. Problems were gone! Or so I thought . . .
It happened to me again yesterday. A long freeway run followed by heavy stop-n-go in Burbank. At first the throttle seemed sluggish. Then I saw that when I'd come to a stoplight and go into neutral that the idle would hang at 1500ish and then drop down a few seconds later. A signal or two later, the idle would just hang at 2250 and not come down. Light turns green, I get on the gas, wrench light comes on, car dies, lather-rinse-repeat.
Thanks to some favorable green lights, I was able to get it back on the freeway and home. In a familiar neighborhood and close to the house, I couldn't replicate the failure. When I parked the car, I popped the hood and felt the throttle body. It was hot but not bad. BUT the housing around the throttle actuator motor was HOT HOT HOT. I couldn't touch it for more than a second or two.
So here's my question: Is my throttle actuator going bad and making the throttle body act funny? Or is another binding throttle body making my actuator get as toasty as what I felt last night. I suspect and fear that it's the latter.
I'm going to try to replicate the failure again today before calling Edelbrock tomorrow. But I thought I'd ask for some opinions here first. Any thoughts?

What was your reason for replacing the just-fine-even-for-FI, stock TB? If you had searched the forum you'd have seen that aftermarket TB's provide no performance gain on our GT's (besides the placebo effect) AND are known to be nothing but trouble.

Who makes the edlebrock throttle body? Can't you use a gt500 throttle body with the E-force?

The E-Force uses a 85mm mono-blade throttle body. You have to take out the spring and retainer from the stock TB and put in the E-Force TB. The spring has to be clocked just the right way to work or you get the 21xx codes and it won't work for crap. Always operate the throttle by hand before installing. Ask me how I know....

I bought the frpp throttle body because it came with everything on it, just like stock and it's been completely trouble free.

If you knew anything about the Edlebrock blower, you'd know that it comes with a throttle body. Just doing to you, what you did to him, lol! A larger throttle body does increase hp on a PD blower car, even at only 10psi. There's plenty of dyno proven results (20+hp) from people with no skin in the game.

Not to threadjack my own thread, but nice bike. I've got an '08 1125R!
