I could do that with the old coil pack. So keeping fingers crossed that was it..

It sounds like it was, it sounds like all is good now.

Well, you may want to check the compression on your cylinders and make sure that comes back fine. The plug from cylinder #5 didn't happen to be abnormally clean, did it?

they where all clean just put them in right after i bought the car about 2 weeks ago. I will check the conpression tomarrow. I have been checking the water levels and they have been good no lose since I bought the car. No water in the oil or vise versa. Its not burning any oil and no white smoke coming out. I am thinking a burnt valve now. what are your thoughts ?

I don't think a burnt valve would get better with a new coil for a few days, then go bad again.

I'd suspect instead that maybe the connector to the coil primary is loose or you have a loose plug wire.

Pull lightly on the wires for the coil primary and see if the connector just pops off. If so, you probably found your problem. Also, inspect the coil ground wire to make sure it is clean and secure. Then inspect the terminals in the coil connector to make sure that they are all clean, straight, and not pushed into the connector housing.

A compression check should indicate if the problem is possibly a burnt valve.

Ok I checked every thing that you said and all is good. the wires are all tight and every thing I was not able to get a conpression check done today had to work a 14 hour day. I hate thoes I was able to check the plugs a agine there is just a tiny hint of a little oil on the plugs and would you beleave also that the people that I bout the car from had new plugs put on it but did not gap them. all 6 plugs where any where between .58 and .64. I regaped them cleaned them to .44 book says .42 to .46 was the gap on that car. I am hoping that was the trouble. cause the code went away and the power came back once agine. will see If it does it agine will get a conpression check.
