my svx WAS broken ...i swear!!

[rmjjensen]

On friday I hopped into the svx, started driving, it's in it's high idle cold start mode (sure fine). But then as I come to a stop the idle DROPS to 1,000 (which is actually high), car is shaking a little, check engine light pops on.

Then 10 seconds later the engine revs back up into high idle (guessing open-loop system from the ecu). Then after a few moments it tries to ease the idle down (closed loop system) and it fails. Same thing, idle SLAMS to 1,000 shake and CEL. 10 seconds later ...high idle is back. [and the car is fully warmed up at this point]

What normally happens is I'll start it up, it's cold, idles high. Then I drive it warms up and the idle will lower gradually to a steady 600-700 rpms nice and smooth. Not on Friday.

So I drove back to my house in open-loop mode and was pissed off ...called my friend told him he had to pick me up and I just went out as I planned.

Saturday I investigate and guess what - SHE'S RUNNING FINE!!!! It's now sunday and it's still driving good.

So what gives? I can't pull codes because now there's no more CEL. I need my SVX to be reliable and this can't happen on my way to work.
