Re: [T3] Poor hot performance.

I've had FI vehicles vapor lock.  This may sound really weird, but it really
works.  Get some wooden, spring-type clothes pins & put them on the fuel
line where it looks like it would be the hottest.  Instant fuel line
radiator.  Some people would tell you to paint them black or silver,
depending on who you talk to. ;)


--- You can also get vapor
lock, where the gas actually vaporizes in the fuel line, leaving the
pump with nothing substantial to suck. This can happen while running,
usually in stop and go city traffic.  Another ill that FI doesn't
