Over the year I've had my car I've learned a few things.
These engines run hot. Deal with it or do something about it. I tried to do everything and went as far as to change my waterpump to fix it. Still no good. It gets hot and that is that.
These cars have a [censored] vibration at idle. Deal with that too. Although I've fixed mine to a managable vibration by changing the plug wires. It helped more than I thought it would.
Zetecs have many aftermarket parts. Look up the focus parts list and many of them can be transferred over.
Yes I know the last part really doesn't have much to do for this thread but I did say I've learned a FEW things.
Like I said, I changed my plug wires and plugs, cleaned the maf, and other misc. things that only helped a little. As long as the car isn't going dead (like mine was) then you should be ok.
