the check engine light is blinking and my 03 Nissan exterra is running rough
If your check engine light is blinking that means an ignition misfire has been detected
have vehicle scanned to determine the problem
Check engine light, rough running engine, no start at all.
Check the EGR vavle
service engine light on? Have vehicle scanned to determine problemCheck for vacuum leak
The check engine light indicates that the computer has detected a "fault". Use a code scanner to find out what the computer has detected, that is PROBABLY the reason the engine is running poorly.
It means there is a emission's sensor is indicating a problem with the system and needs to be checked out. A scan tool can retrieve codes from the Electronic control module. From the code given you can pinpoint the issue of the rough running condition.
Yes, a mass air flow sensor is probably the number 1 cause of the check engine light in your car, as long as the engine is not running rough. But a couple other poss. are coil/spark plug wires (if the engine feels like it is running rough) front or rear oxygen sensors Evap leaks (gas cap not on tight) But besides that, that is about it for check engine light issues on your car, if you get me the code I can tell you exactally what to replace.
I washed my car at the car wash, then I washed the engine with engine/tire cleaner with the engine running, since then my check engine light has been on. Sometimes it blinks fast, goes off and then comes back on steadily. The engine sounds like sputter, misfire, rough sound from the tailpipe. The entire engine seems to be running fine, no shaking or bouncing, just running normal. What is the problem? Thanks for your help.
check the oil in engine to see if it has coolant in itwhite smoke is caused by coolant or water burning with fuelsounds like you have a blown head gasketi would also find a better mechanic
If the check engine light is flashing that means an engine cylinder misfire has been detected . You can drive it in for repair , just avoid any rapid acceleration or deceleration because you can damage the catalytic converter
