[DML] Re: Update on rough start issue...still need help please



Derek,
When your car is running do you smell raw gas or heavy exhaust 
fumes? has the air mixture unit been drilled or punched? has the 
thermial time switch on the water pump been replaced? has the intake 
been removed recently? have you checked all your vacuum lines to 
make sure there all connected even under the intake, do you hear 
vacuum leaks by your canister conpartment? have you changed any fuel 
lines or filters lately?changed or removed you air regulator 
stabilizer or swapped out your RPM relay, call me if you need I will 
try to help.
