i second the coil. its a very common problem. except you have a coil for each bank of 4 cylinders not 2 lol
the exact same problem has happened to me. i changed plugs, wires, cap and rotor, and finally changed coils and it fixed the problem
is your ac still cold? if its just stuck on low fan speed its the fan speed controller. its a little circuit board that the temperature control knob is on. you have to replace that. the fan speed is controlled by the climate control.
well if you are doing all the work yourself, it all depends on whats busted but its seems like your head gasket is blown right? so replacing the engine isnt something that is needed. but if you decide to do head work at the machine shop then it might get pricey. so just take both the heads and get a pressure test and resurface.
honestly there is not much you can do to get the car not to sound like a chevy v8. reason 1 is because it is a v8. reason 2 is it has the same firing order as a chevy v8. of course bore and stroke have alot to do with it but why does an f355 sound the way it does? firing order plays a big part. the 1uz and chevy small blocks both have a 1-8-4-3-6-5-7-2 firing order. the f355 fires 1-5-3-7-4-8-2-6.
ummm... these cars use sealed bearings and the hubs are pressed on. you need to remove the entire hub assembly from the car and use a press to push out the inner hub from the bearing and push the bearing from the hub carrier. so basicly take the hub to a machine shop or somewhere that does press work and have them press the new bearing in
