Car Forum / Nissan / Nissan Cars / July 2008KA24E Engine Vibrating
The engine in my 1995 pickup vibrates on idle. It's not missing at all. The vibration goes away above about 1,000 rpm. I've changed spark plugs, rotor, and distributor cap with no improvements. The motor mounts are tight. Any suggestions? > The engine in my 1995 pickup vibrates on idle. It's not missing at all. > The vibration goes away above about 1,000 rpm.

My '97 pickup has always had some vibration at idle. Is your truck shaking or are you saying that that you detect some vibration through the steering wheel at idle. A Nissan pickup at idle ain't gonna feel like an Infiniti Q45 at idle. > The engine in my 1995 pickup vibrates on idle. It's not missing at all. The > vibration goes away above about 1,000 rpm.

I know my 97 Nissan PU's engine is running when sitting at a light since I can feel it through the steering wheel. After all, it is a truck, and not an Infiniti, and at least 13 years old, at that. Perhaps the vibration is normal. I'm the original owner of the truck, and it just seems to me that the vibration from the engine has increased over the years. It only has about 92k miles on it. It does run well. I guess I should leave well enough alone. Thank you for your thoughts. >> The engine in my 1995 pickup vibrates on idle.

In my wife's Altima with the KA24DE, I've always been aware of a vibration at idle, around 600 rpms. If I turned the AC on, the vibration would get a bit more pronounced due to rpms dipping a little lower to like 550 rpm. But, if I raise the rpms just past 600 rpm, at about 650, all vibration is gone as if it never existed. And there is no vibration at all in the rest of the rev range. I figured it's an engine mount going bad and I'm leaving it alone untill the situation gets more urgent. CD on 7/22/2008 11:19 AM codifus said the following: > >> Perhaps the vibration is normal.

It's a little hard for a 4 cylinder engine to run smooth if the rpm falls below the recommended idle speed. You'll have to find out why the idle speed is low. It could be a number of mechanical problems or a Throttle Position Sensor (TPS) problem. The cheapest remedy might be just to clean the throttle body using a throttle body cleaner spray available at most auto stores.
