hi guys

got the brakes machined today no shudder now mmmmmmmmmm nice.

but i have a slite surge on pickup and cruise.i was told it could be gunk on the air flow wire.so after a short burst to test the brakes i took out the filter (needs replacing) wires clean.

buuttt theres whiteish greyish stuf inside the pipe between the manifold and the aircleaner .its near a little vacuum inlet tube moter side ofair flow wire . it looks like when black plastic goes a funny colour from a solvent .you can scratch it of havent washed it yet .duno wether to or not or what to use. thers no leakage at any of the joins clamps are tight .

what s this stuff and wheres it from should i worrie
