2006 IS250 - Loss of Acceleration, VSC, flashing Check Engine
I was driving on the highway (2006 IS250 w/ 134k miles) when suddenly Check VSC and flashing Check Engine light came on, and there was significant power loss. I pulled to the side of the road, shut the car down. The car engine was running very rough, the RPM's were high despite a slow speed. Gave it a sec and turned it back on and everything is now fine for another 100+ miles.
I've saw a few other posts of similar situations. I'm about 10k miles overdue for spark plugs (getting them done next month). I realize this could be anything, (Carbon Build-up, spark plug, ignition coil, etc), but with no stored codes I could find from the incident where do I start? I guess spark plugs are a given, and maybe replace the 3 rear ignition coils at the same time to be on the safe side (considering the work in removing the plenum).
The car runs perfectly, no idling issues, or sputtering that so many people mention as a result of the carbon build-up. I do burn oil as mentioned in a previous post (about a quart every 1500 miles). Unfortunately, the incident has shaken my confidence in the car. There are more than few highways in NYC where it would be terrifying to lose power like that and not have any place to pull over.

It would be a little easier if there was a stored code to pull. If it happens again anytime soon I will have to take it in. But it's almost a moot point. Paying for a rebuild is not an option. Might as well drive it until the engine blows.

I had same thing.......called dealer and he said that you must ALWAYS make sure that your gas cap is on very tight after each time you visit the pump. This has happened to me twice and both times I tightened the cap and drove about 15 miles and lights went out. Give it a shot..........you have nothing to lose.

This did happen shortly after filling the tank and it crossed my mind maybe it was just bad gas or something. I'll keep an eye on this.
Thanks.

Well one way to figure out what happened is to read the codes. The VSC has nothing to do with your problem. Your ECU went into safe mode and the VSC is disabled to relieve strain on your engine and this will happen anytime there is a problem with the engine.
I would bet that it is a carbon problem and the reason I say this is because you burn a lot of oil (should have installed a catch can). At some point it will affect performance and you will notice it at higher speeds than at lower speeds or idle. The only other thing I would guess is fuel pressure. Your fuel pump might be going. But again I will bet the carbon build up is at the point where it is affecting performance at higher speeds.
A code scanner is like $20 bucks off of Amazon and TorquePro is $5 bucks on the play store. It's the number one thing everyone should have. Why not know what is wrong with your vehicle when something breaks.
