take the egr tube off, plug it and stick it back on to keep the environmentanalists at bay.
run a good fuel system cleaner through to get all the carbon shit off the inlet valves and will be running better real fast.
or just move to a country like mine where there are NO SMOG LAWS.
I have no egr, no cat , headers amd big pipe and the man cant do a god dam fukin thing about it.
