Hi everybody, I have a 2005 350z, the SLIP sign flashes on the panel when I do turns on a curve , went to auto zone and the test gave me p1283, which is bank2 sensor 1, air fuel mixture, so I replaced it but the Slip sign just popped up again, what it does to I have to take my foot of the gas and let it role for few seconds before I get control again, if it's flashing and I push on the fas, it won't accelerate , no other abs or TCS signs pops up on the panel only slip. Any idea before I spend $175 at the dealer just to diagnose it?

 

What are your wheel/tire sizes?

 

The front tires are 245/45R18, the rear tires are 225/45/R18? Wait a minute, isn't the 245 bigger and they're supposed to be in the back?

 

245 should be in rear, but i can't remember if it 40 series (havent had a z in 11 years), but traction control is sensitive... so it might think the rears are spinning faster than the front causing the slip/tcs to show and cut power

 

You see I changed the car oil and tire balance 3 weeks ago at firestone, the name says it STONE, first the tech guy didn't tighten the lug nuts so when I drove it the steering wheel was shaking bad, turned around and the tightened them but right after that the Slip sign start to appear on the dashboard, I called them and told them that they did something wrong, then they suggested it could be the ABS sensors, I was about to buy all 4 sensors online. But when I read your message for the tire size I noticed that they installed them wrong, big tires upfront and smaller tires in the back,OMG.
