Engine Performance problem
2003 Nissan Sentra 4 cyl Front Wheel Drive Automatic 11700 miles
This question or concern I have is that on my 2003 Nissan Sentra 2.5L. Its idles hard and rough at red lights. I have had spark plugs replace. But not he wires. Still the same idling issue. A mechanic told me to replace my existing sysytem to clear up engine breathing, He said the idling is from the engine trying to push out to much air through exhaust pipes that are clogged or too small for the enigine. Also I recently noticed that When accelerating from a stop I can hear a low rumble. Like the sound of an after market muffler or exhaust tip. What could possible be wrong the car and what should I do to correct the issues?
have the same problem?
