Hey guys. I just bought a 19 na with 200k miles on it the other day and on the long 5 hour journey everything was great besides the ol 5th gear pop out problem but I knew about this and plan to buy a new trans. About 20 minutes from my house I started really getting into the throttle. (Dumb I know) after about the third time when I shifted to 4th I started losing rpm fast. After awhile I came to a stop and when the car started to idle it began surging bad. Also it has a gas smell. Can anyone
