I went Ahead and replaced one coil at slot 5 for a week no problem was detected and now its back again.
They guy who out it in said he tested the coils and found #5 at fault and thats what was replaced.
very weird that my coolant level went down quite a bit while driving couple of days ago i had to top it off , but there was no visual leak to be found anywhere or any kind of smell.

 

Check #5 "slot" wasn't identified wrongly - happens all the time

Keep an eagle eye on coolant level and be sure to find where it's going if it keeps dropping.

 

You mean go back and let them test it again?
yes have been checking for coolant every evening

 

Depends how they identified it. You'll know if it goes back to having troubles, I suppose...

 

On coolant issue:
Absolutely no change on level since i topped it off.

On the hesitation:
It seems to be doing it again but not as much as it used to/
Doing some more research I found out about the Techtron and added that today.
also found some posts in the forum almost similar issue and was identified as the tube, hose and oring.

Being a noob i cant tell anything does these two posts sound like my issue.

 

Just get an OBD tool - they're cheap. See what codes. Far cheaper than guessing. General Tech has a thread...
