200tq won't run

[Ameer Antar]

usually the CO mixture screw in the fuel dist. doesn't get messed w/. I 
give it a 90% chance that it's vac. leak as others have said. If you take 
out the air filter/cover and push the air-flow plate up manually, while the 
engine is running, you increase the amount of fuel to the injectors. If 
raising the plate a bit helps, then there's either a leak or the CO screw 
is misadjusted. You can usually tell if the screw has been touched if there 
is no aluminum or rubber plug above the screw, which is between the fuel 
distributor and air-flow plate. If it's still there, the screw should be 
fine...it's a vac. leak. If there's nothing covering the hole, get the plug 
from the dealer, otherwise your letting in small amount of unfiltered air 
into the engine...good luck
