Loud exhaust explosions, too much carbonization and fuel after the throttle valve
While disassembling the throttle body, I noticed that had too much carbonization and fuel (actually leaked as can be seen on photo) right after the throttle valve (I had cleaned about 1 year ago)... Is this normal? Another problem that I have is the exhaust (it's seems to be) explode(really loud pops) some times when I accelerate and leave the car go by the inercia...
Why is there fuel there? Bad valve timing? And is this causing the exhaust pops?
Thanks!

The only way I know of for fuel to enter the throttle body is through the fuel pressure regulator. If it is bad it will let fuel leak past into the intake. Pull the vacuum line off of the FPR and if it is wet with fuel then it needs replaced.
The popping is from having an excess amount of unburnt fuel in the exhaust.
