Hi,
No the car is driving fine. The sound of my exhaust is not louder while the rev is jumpimg. I can see the rev jump in the corner of my eye. It happened this morning coming to work as well but i wasnt sure. I saw it again so now im certain.
Before all this happen, my car would just shut off with the revs dropping while i switch on the car in the morning for work. It would start on the second try everytime. Funny thing is, the car would start first time during the day even if i start the car after work which it havnt been starting since the morning.
Cheers
Henry
