Hello everyone I'm having a weird problem. When I first start car and let it warm up if I put in drive and accelerate a little too hard the wheels spin. Doing a little burnout so I have to slowly throttle it. This isn't me flooring it, this is just me taking off. He happens mostly when I first drive the car then it kinda goes away. Could this be my torque converter going ? I had new fluid put in last year when I replaced one of the tranny solenoids. I feel like I'm driving a 600hp car that just breaks loose when I accelerate, I wouldn't mind if I actually had that ! Lol

 

Need some more info, Gs300 GS400 GS430? Whats tires? What Air pressure.

 

Gs400 tires are nanking and 35psi

 

maybe you accidentally got race gas mixed in with your regular fuel at the gas station. not likely but it's a possibility.

 

If the trans temp is cold like below 70 degrees on the trans it does shift harder from what I have experienced. If you talking about acceleration from stop. There could be a few things. most likely being sticking throttle cable/throttle body. I recommend cleaning the throttle body and maybe lubrication of the cable to the throttle body. If the throttle cable/body is sticking your pressing on the peddle and nothing is happening until it breaks free and that position is if a lot more throttle than you intended.

 

Well it happens even after I let car warm up to operating temp. And there are no hard shifts it's just the acceleration is enough to have to "throttle" gas when taking off. I will try cleaning throttle body and lubricating.

 

Can it be a TPS issue? Perhaps it is malfunctioning where it skips over light throttle response. If you have s live scanner see what the TPS reading is at idle and during initial acceleration.

 

I would also clean your mass air flow sensor while your there.

 

How old are your tires?

 

I'm going to put new tires on just incase.
