RE: 4KQ Sneaky Power Loss Alert!

I knew there was a reason the Ur-q's could keep up.  ;-)

At our track day last weekend at PIR, (NW Audi Quattro Club), a 
bunch of us 4KQ owners were comparing notes.  I was puzzled by 
the fact that my recently installed 
full-throttle-fuel-enrichment black box from AVS wasn't 
working. Gary Erickson pointed out that the full-throttle 
switch not working could account for it, so we did a simple 
test of the this stupid little switch... it wasn't working! 
which means I've been driving around for god knows how long 
without even stock full-throttle power! (let alone AVS enriched 
power.)

Here's the kicker.  After lining up a bunch of red 4KQs for a 
group picture, we all did the test. Of the FIVE 4KQs tested, 
FOUR had inoperative full-throttle switches! Only Gary's 
worked.

Here's the test.  WIth the engine idling, depress the little 
lever on the switch. wait several seconds.  The motor should 
bog down noticeably as the idle fuel-air mix gets overly 
richened.  If there is no change, your switch is inoperative.  
Try unplugging and re-plugging its harness connector a few 
times to see if its oxidized, or replace. (Gary thought one 
might be able to get it open and possible repair it).

If not familiar with the switch, just manually work the 
throttle lever and note the switch that gets pressed at the 
limit, just a bit aft of the center of the valve cover.

Thanx Gary Erickson!

Cheers,
Leigh

P.S.  I still managed to figure out the lines at PIR better 
this time and got down to a 1:39 lap even without proper 
full-throttle power.  I was repeatedly catching a BMW 535i in 
the corners  despite the straightaway difference. Quattros Uber
