whoa wanna talk about scar. yesterday at this stop light this little bastard import wanna be was revin his engine tryna start stuff i was just minding my business but NOOOOO!! so of course i had to shut him up but than the drama starts...... after stompin the riceburner i go to pull into the local wawa to get something to eat (something i intended doing from the get go) i go out to my car and start it up and this blue smoke starts comming out the exhaust.... now the cat makes this nasty grinding noise after i fire it up and let it run for a minute than the car starts to idle up and down up and down finally it runs steady at 1500 r.p.m. did i screw my poor baby up or what car has 180k miles on it
