    if not the vacum lines then it's either the IAC valve (idle air control valve) or if it's the american made modle theres is a secondary air boost valve that the only soul purpose of it is to help warm the car up on cold morning you can either replace that valve of block the valve off, i used a peice of pepsi can and it purrs like a kitten!!

Where is idle adjustment screw on 1989 nissan sentra


on the throttle body. the gas pedal cable from inside the car leads under the hood on drivers side to the throttle body. throttle body is attached to the intake.
*****you should not have to adjust your idle. itusually means that there is a bad sensor if your idle has changed suddenly,****
what exactly is the car doing? ex.fluctuating rpms?, low constant idle?, high idle?

The test connector is in a holder at the back bottom of the fuse/relay box on the passenger side fender well. There are 2 parts to it: the main connector and the ground, you will need both connected to the diagnostic tool to get the codes.
Check your IAC (Idle Air Control) valve on the side of the intake. These get carbon fouled and tend to stick causing high rpm for extended times. Also the EGR valve should be checked (under the intake) as it will cause rough idle or stalling near idle.

2002 escape 3.0 idle fluctuates and misfires when driving


No such thing as a tune-up

All you did was replace spark plugs which should be
done every 3 years

Oxygen Sensors get replaced at 100,000 miles which you
also did

You most likely have an intake gasket leak,smoke test
the entire Evap System & Engine

You also are have bad igniton coils

Ford probe idle fluctuating


Sounds like you have bad gas. It can get strong mix of gas to give you the right idle, but when it has water mix, it will cause the car to fire like it should. This will then give you a low, rough, or just cutting off idle. Try mixing water remover in with the gas. You may have to drain the gas out or just drive it like it is until the tank is almost empty. Fill up with gas (from a different store) and you may want to change the plugs after the good gas is through the system. I'm not saying the plugs are bad, but there may be a lot of moisture beads from the water sitting causing rust.

88 dodge dakota has rough idle and stalls at slow down.


Change/thoroughly clean the idle control solenoid. It may be sticking and causing rough idling.
Cleaning it is unlikely to be more than a short-term solution.
