HI PEOPLE, NEW TO THE SITE SO I APOLOGISE IF THIS IS WRONG THREAD IN WRONG FORUM,
BASICALLY MY E46 318CI IS ABIT OF A BANGER! ... I HAVE THE MAF SENSOR ON WRONG WAY ROUND TO MAKE IT RUN BETTER WITHOUT ANY SPLURGING OR LACK OF POWER (IS IT DANGEROUS OR HARMFUL TO THE ENGINE? )...

I ALSO HAVE A GEARBOX LEAK AND IT LOOKS PRETTY DRASTICK ..( SO DOES ANYBODY HAVE ANY INFORMATION HOW TO CHANGE TRANSMISSION OIL??)

AND ALSO HOW EASY IS IT TO CHANGE THE THERMOSTAT HOUSING ??.... I HAVE ALREADY CHANGED THE EXPANSION TANK WITH SUPERVISION OF A TRAINED MECHANIC FRIEND.. WHOM HASNT GOT TIME TO HELP ME OUT AT MOMENT... SO ANY HELP WOULD BE GREATFUL

I ALSO HAVE A STICKY ACCELARATOR AT TIMES.. I HAVE PUT WD40 ON THE CABLE BIT IN ENGINE BAY AND IT SEEMS TO HAVE HELPED IT BUT I HAVE A GUT FEELING ITS GUNNA POP UP AGAIN! LOL

PLEASE HELP IF U HAVE ANY KNOWLEDGE AND SPARE TIME TO EXPLAIN/SHOW ME VIA PICTURES OR VIDEOS
I WOULD BE VERY GREATFUL

THANKS JAI
