Hi Maylene
I got this issue with my car, what did you do to solve this problem?

regards,

2000 Mitsubishi Galant
keeps throwing p0400 code
has a intermittent rough idle under load
tested vacuum at throttle body 0 at vacuum line with yellow tracer stamped A on the throttle body port
get about 17 at The hose with green tracer stamped E on the throttle body port
cannot clear the port the hose with yellow tracer going to egr solenoid...
can I just tee off the e port to supply vacuum to the egr solenoid untill I can pull throttle body and clear the port?

Any suggestions would be greatly appreciated
