Hi so I have a 04 rx8, that I just got done rebuilding the engine in.
I've got the car running great with over 300 miles on it so far. The problem
I'm having is when I'm driving the car, if I make a sharp right hand corner
Turn the steering wheel has a bad catch in it, feels like the wheel is folding back
Lol and steering wheel feels like it has no power steer to it. But when I pull out of the corner, the airbag light will start flashing the remain on. But it's only to the right. If
I drive at lower speeds and take lite turns it's fine. And it's only when the car is moving. Sitting still the steering works fine with no binds and no airbag light.
All tirerod ends and so on are all good and tight. Plus driving at low speeds sometimes
The rear makes a slight bump and the dsc car light will flash. But not at all times.
And when it does it, it feels like a locker in the rear diff lol or may be the abs and tcs
Acting up lol but no lights. If you can help would be GREAT thanks.
