Saturn Repair: 1992 SC power issues, coil pack, coolant

Question
Hi Ken,
I have a 92 SC with 170,000 miles. Every time I drive the car it runs rough with no power for anywhere from 5-15 minutes and then it is fine. The check engine light never comes on. I have replaced the plugs, wires, and I have a new coil pack, but I haven't put it on yet.  Any other possibilities that I should be looking at?

Answer
Hi well i would put a scanner on it to see whats going on ..just to see if there is a code and what the data says....But are u loosing any coolant the heads a known to crack and if u have a small leak over night into the cylinder it will run rough untill it burns it all out .. it may also be other things .but check out the coolant first its very common
