I don't know much about the EGR valve yet....but i know some autoparts stores can reset your light for free...just call around.
why is my check engine light on 99 mustang gt
Which engine? If this is a check engine light or emissions test failure be certain ex. gas & intake passages are clear. Bob
A blinking check engine light indicates an engine cylinder misfire has been detected
One scenario could be that the sending unit for the gauge on the engine is bad. Try to locate it and replace it if it is corroded and check the wiring to it also.
yes definately. replace the o2 sensor, and you might want to also replace your pcv valve
The check engine light being on means that a malfunction has been detected with the emission control system . Have your Mustang scanned for any trouble code (s) in order to diagnose and then repair the problem so the check engine light can be reset
Unplug the battery for like 45 secs.
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
There was a recall on the windshield wiper motors. Check with your locate dealer and they may replace it for FREE!!!!
There is not one sensor. All the ECM sensors are tied to the check engine light.
