Did you read post 2?
The tube to the map censor is probably broken , they get fragile from the heat . Just look for a tube ( about 5mm thick) going from the rear of the plenum to the map censor near the brake booster .
REAR of the plenum NOT front.. You will find a steel tube about 30-40mm long and about 4 mm thick, get a new tube and plug it in there, don't even try to re-use the old hose, the same thing will happen again ..
