One member suggested checking the spark plugs. I don't think I have changed them since 2003 and the car now have 64000km on them. Haven't tested them but I was thinking it wouldn't hurt to change them.
Really want to try Pulstar but heard that it doesn't last long and a lot have been using NGK iridium plugs.
Thank you

Sounds like a 7 wire kit might fix at least 2 of the 3 issues if you don't have them now.
