When I start up my g/f's oz it sounds pretty rough (like a slight hesitation) also the idle sounds kinda like a desil engine. What could be causing this,and what should I keep an eye out for?

Basic tune-up stuff... Sparks, filter, oil change?

the oil and filter were just changed and it only has 25k on it.

Spark plugs and may be an air filter?? If not, just try to reset the ecu.

Mine sounds like a diesel but that's cause it has different pistons and its 32 degrees outside.

Well I dont remember how the motors supposed to sound I havent drove an oz since I had my blk one and I only drove it for about 3 months before I traded it in for my r/a but I dont remember it sounding anything like this oz. How do you reset the ecu? and can that negativly effect anything else?

^^^You just disconnect the negative batt cable, wait 10 minutes (or so...), reconnect, let idle for 5 minutes, then drive around (but nothing racey).

plugs, filter, oil, PCV valve, check battery, plug wires, coils, etc.

i thought resetting the ecu you had to remove the Positive side of the battery? Or it doesn't matter. I've done it w/ POS side and it works for me.
