Question about 2002 Ford Mustang
Vacuum hose going to the pvc valve was busted, but the car would run. Replaced the hose, and car will not idle, immediately dies. Put the old vacuum hose back on it, and will run. We also replaced the pvc valve but still will not idle. Any suggestions?
Sounds like the computer system readjusted it self to the specific air measurements that the busted hose was allowing in to the engine.(This is only relevant if you have a 1987-up) turn off the car, remove the battery cables, and let sit for 45 min, this is ample time to reset the computer memory. Reattatch cables and start. It may run rough for a few miles but if after say 50 miles of driving, if it still wont idle, than you may need to replace sensors. (MAF, intake sensors, O2 sensors, etc..)
