My car wasnt going over 75 and then when i left pepboys today with **** for an oil change it wouldnt go over 60 then it stalled and the wheel locked while i was changin lanes and i got lucky not to hit the gaurd rail. White smoke started rising from under my hood and the car wouldnt start then when i finally did start it stall when i let the rpms drop under 1200. By the time i got it the one mile to my house it wouldnt go faster then 25 and is bucking like crazy.

I dont know what it is! i just changed the spark plugs to autolite xps and thats the only thing ive done.

 

when the car was going at X miles an hour what was the tach reading? if the car is redlined and the car is going 50 mph then the tranny is the cause. As for the wheel locking you have me. I am assuming you have a 700 right?

 

I blew a head gasket thats what it was. the tranny is fine.
