[T3] 72 square, FI behavior ?'s

["Drake ." <vw_type3@hotmail.com>]

<x-flowed>Well I have just completed a 400 mile round trip with the new motor, in the 
old girl. Things went great 75 all the way up I-5. I just estimated gas 
milage and got somwhere around 32 mpg (160 miles, 1/2 tank)

I took out the section of wire that had been installed inline with the head 
temp sensor, that seemed to improve the MPG as I got better MPG on the way 
back than the way down. You generally get better MPG going down I-5. Smells 
a little better too, I could smell that it was running rich before I removed 
those resistors.

I still need to check the fuel pressure, and I havent double checked the 
diaphragm on the pressure sensor yet, those are the two last things I really 
need to check to ensure that everything is working, more or less :)

There are a couple of odd behaviors that I wanted to ask about because it 
doesnt seem right to me at all, but this being my first experience with the 
FI I just dont really know.

1. After I removed the extra resistors from the head temp, I cant get the 
idle above something like 800 (haven't checked exact RPM's with the tach 
yet) but it sounds just a little slower than the previous idle with the 
resistors installed. I unscrewed the idle setting screw past the point where 
the idle didnt go any higher, adn then screwed it back in until the idle 
dropped a touch. I then backed it out slowly again until it reached the 
highest point, and tightened the locknut. I would think that I should be 
able to get the idle higher than this, shouldnt I?

2.While sitting in the driveway, engine at idle. I open the throttle with my 
hand, just a crack. The engine will accelerate, then drop back to idle. Open 
a little more same thing, little more same thing. This happens until I get 
the throttle something like 1/3 open perhaps a little more than that. Is 
this a normal behavior with the FI?

3. One other thing is that the car will buck a little at low speeds. 
Basically if you dont accelerate semi-hard from a stop then it will buck.

Other than those things the car seems to be runing pretty well, accelerates 
well...for a heavy car with a stock 1600 that is. She cruises beautifully 
though.
