Want this question answered?
my 1990 300zx is idling rough what could cause this?
If an alternator is going bad it can cause a rough idle in a 1993 Subaru Legacy. Cold temperatures in the winter can also cause a rough idle in the Subaru Legacy.
There are several things that can cause your 1993 Nissan 300 to idle rough. The most common cause is dirty spark plugs. Bad spark plug wires can also cause the problem.
The most common cause of rough idling would be a bad or clogged fuel injector. Also look for the hose on your EGR valve. They tend to come off in hot weather. If the hose comes off the engine will definitely run rough. I had to put a small hose clamp on mine to keep it from comming off. Spiritchsr1
No. The idler pulley only maintains tension on the serpentine belt. A faulty idler pulley can cause noise and a loose tensioner arm can cause belt slipping but other than having a similar name, it has nothing in common with engine idling.
Rough idling is whenever the vehicle's motor "misses" or does not fire causing an imbalance and a loss of rotation reducing the motor's power and causing excessive shaking.
Yes it could and it will cause rough idling and a missing when giving it gas.
I had a similar problem and it was my coil pack
try checking that there is no moisture build up in the sparks as this will cause it to idle rough but drive fine. if u do find moisture try spraying some crc 556 or other lubricant in the spark cavity and check the spark plug gapping. if its still idling rough after that take it to a garage :-)
