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.
could be the egr valve is dirty and needs to be cleaned. if there is soot build up, the valve may not close all the way which can cause a rough idle. if it ever stumbles while accelerating, that can be from it not opening when it should. cleaning it can be an easy 30 min job that anyone with basic mechanical skills can do. sometimes.
All are wires firmly seated? Did wires get crossed upon installation? Defective wire? Defective plug? WRONG Plugs?
Out of personal experiance, the outback is a little more rugged, it has better suspension, but the legacy does just as well. I have had 2 legacy's, a justy and a svx. and lived in the catskill mountains, the legacy's both did a wonderful job in the winter time, I highly recommend both the legacy and legacy outback, but if you live out in the sticks with roads that are really rough you may want the outback. Its a little smoother on rough roads. But believe me, you will be VERY happy with either one! A subaru has always gotten me through horrible winters when other cars get stuck. If you are going to buy a used one, make sure it has all service records, if it has not been properly maintained you may run into some problems. I bought one in NYC that was not properly maintained and ended up putting more money into the car than I paid for it. If maintained properly it will last FOREVER! It is not uncommon for a Subaru to get over 300k miles. Make sure before you get it, it has had the timing belt replaced if it has over 90k miles. Or if you get a manual make sure the clutch is in good shape. If you go for the legacy get the LE. It is a better car all the way around. In all the years we have had subaru's, ours never once went in the ditch. But do not think they cannot go in the ditch, they can, but if you drive carefully it is very unlikely.
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.
The 1998 Blazer could have several problems causing rough idle. Check the air filter, fuel pressure, and EGR valve for a clog to look for the problem.
There are many things that can cause a rough idle on this car. The computer could be going out, the engine may not have enough oil, and the engine may not be getting enough fuel or electricity.
It can reflect off a rough surface but the image is not clear ,causing an irregular reflection.
My 1986 Honda Accord Dx just started idling rough and dieing at turns and stops it is a carburated 2.0 witha maunal transmission
Well...the misfire on 1 and 3 would explain the rough idle. The misfire could be from worn plugs, wires, bad coil, or bad injectors.
e.g.r. valve replacement fixed mine. symptoms where rough idle and "surged".
The general opposite of rough is smooth.For a person, the opposite of rough could be gentle, polite, courteous, refined, or sophisticated.For rough meaning uneven or bumpy, the opposite could be even, regular, flat, or level.For a "rough estimate" the opposite could be accurate, precise, or exact.
The Corolla could be shaking for many reasons. Start by checking the wheel bearings and brakes for wear. Then check the engine to see if it running rough, causing the shake.
