C0181 - Throttle reduction motor circuit malfuntion: Car bucks 2K RPMs I have no dash lights on except for TCS: I have an SLP reverse module so it stays off from the initial start of the car.
I haven't had any problems with it but the other night after doing 5-6 pulls VS another car this started. It was roughly 45 minutes after we did the pulls.
Around 55-65mph I noticed "bucking"... Almost like if the converter locks too low with a large cam or an M6 is in too low of a gear.
I got the car out of lock up and it seemed like a miss around 2K RPMs.
Plugs have less than 1K miles on them so I doubt it is a miss.
The only codes I have besides the C0181 are MAF/EVAP related which I am SD tuned so those are irrelevant.
The SES light is NOT on.
It did it the night I raced the Supra but 3 days passed and it didn't do it again. Today on the way home I noticed it and it has continued.
It seems like it only does it after I have been driving the car for a while but I'm not sure on that.
Autozones computer didn't tell me what to replace or any sensor. I looked it up and it seems ABS related but no solutions.
Any help is appreciated!
