So...when we were driving home last night in our 2007 Rav4 (4 cyl, 2WD) the VSC light, traction control (car with swervy lines) came on and the check engine light started FLASHING whenever we made a right hand turn and tried to accelerate. It would go into a sort of limp mode until we hit the brakes and got below 25-30 mph...then they would go off and everything was fine until we had to slow down, turn or veer right and accelerate. It only seemed to happen on right turns. So I was thinking bad ABS sensor or bad wiring connection to it..."the ECM thinks we are skidding and goes into limp mode until we slow down." I pulled the codes and all I received was a P0304 which is a misfire in the 4th cylinder. I took it for a spin this morning. Turned right and accelerated...nothing. Got home and checked codes...nothing. Also, it buckles (no warning lights) if you try to hold it around 50 mph...if you accelerate past that or slow down, it stops. But I think this is a different issue by itself.

So, I don't know whether to focus my attention on the ABS system or the spark system. Can the ECM shutting power to the engine during the traction control problem cause a misfire code? Help! Don't just wanna start throwing parts at it.
 
How many miles? Have the spark plugs been replaced?

Mainly just trying to figure out what is triggering the traction control system...but it is intermittent. And trying to figure out about the misfire...the only time it did it was when the traction control lights were coming on. So I don't know if the two are related or if it was just a coincidence that they happened at the same time.
 
I just had the same problem: 2008 RAV4, 188k miles.

I had a code misfire in cylinder #2 some time ago, erased it and the dealer couldn’t make it reappear.

Because of the code, I had the car serviced by the dealer who put in new spark plugs and did a tune up, among other things.

Driving this morning at about 60 mph, the battery light came on. Then all the dash lights came on, power steering disappeared, virtually no acceleration. Then the lights went off. Sometimes the battery light went off. Then this would repeat. I can’t pull any codes because there is nothing unusual showing on the dash now. We checked the battery connections and everything is fine.

I can’t find any mention of this combination of symptoms apart from this post.
