I hit wanna know whether or not the 2005 engine will work on the 2002

There doesn't seem to be any specific speed or conditions to cause this. I'll be driving along and can tell from the sound that the o/d has turned off. Other than the sound of the engine there doesn't seem to be any noticeable difference in the way the car drives.It doesn't happen all the time, only occasionally.
Is there a relay or sensor that could cause this? Or, maybe a short in the wiring to the o/d light?

What's the best way to dry out the computer? It was running fine until a passing SUV caused puddle water to wash over the travelling car during a heavy rain storm 4 days ago!

Power steering not working. Then when everything is turned off returns to normal.

My 2002 Aerio Suzuki starts up runs or idles rough but continues to cut off.

I know the issue with my radiator cooling fan is the relay, but I dont know which relay slot #number I am supposed to replace.

Cooling fan relay defective. Order new one. Problems is all the relays look alike. Cover only marked with relay 1,2,3 etc. Anybody know which relay is the right one? And no I don't have the owner's manually.

happens when am going slow or in traffic

2002 Suzuki Aero

Whenever im backing up turning the steering wheel, I hear a popping sound. 1 machanic told me that I need a right front lower ball joint and another said tie rod end boots.Which do I need?,confused again....thanksforyourhelp.

Had the car hooked up to 2 different handheld computers,1 read 02 sensor and the other cat. converter. Then took the car to a machanic and hooked up to the big machine.He told me that after changing the Downstream sensor,the problem should be resolved??? Where is the Downstream sensor located?And what kind should I purchase? the universal,alternate,etc.?

My belt squeeks when I put the a/c on and have the foot on the brake while in gear. Is this something I can replace myself, there is not much access up above is there a way to access it from below or do I need to take it to the dealer. I purchased a extended waranty good until Feb.2011.
