[chunk]

I have an s13 with a ka24de...im new to nissan's so i need as much help as possible...the car is idling rough but usually runs fine untill it warms up, then it starts bogging down badly...sometimes it does this all the time and sometimes it doesn't do it at all....it has all new plugs, wires, dizzy cap and rotor...i have deleted all the vac system that can be removed...it acts like its missing out and smells like its running rich...i really need to get this fixed asap

wrong forum.

[jacobzking]

have you checked your timing?

[Taniguchi_Is_#1]

replace coolant temp sensor.

[lvlanolin]

could be the idle control valve

[chunk]

as far as i know the timing is good...where is the idle control valve exactly and ill check the coolant temp sensor but y would that effect they way it runs???

[nissan240syan]

bad or dirty maf ?

[carter,wade]

replace coolant temp sensor.

i second that....it makes a big deference, sometimes they get so bad that the vehicle stalls out when it warms up.
There are several ways to know if the coolant temperature sensor is malfunctioning, if the sensor is bad it will trigger a trouble code and the check engine light in the dashboard will come on, you can retrieve the engine code and see if it is related to the coolant temperature sensor, even if the engine control computer doesn't store a trouble code, there is another way to suspect a bad coolant temperature sensor : If your vehicle starts using more fuel than usual, starts having trouble starting when the engine reaches normal operating temperature or you notice black smoke coming out from the exhaust tail pipe, it is very likely that these symptoms are related to a bad coolant temperature sensor

make sure you don't have a vacuum leak...

Flux capacitor is disconnected. Fuel filter been checked? Possibly fuel pump

[chunk]

i have put on a new fuel filter so i guess my next thing to try will be fuel pump...but if the fuel pump is bad why would it run fine and then barely run an hour later???
