93 2.3 idles funny

Ok, the son of the guy I work for has a 1993 Ranger with I believe the 2.3L with 100,000 miles on it. When it is at idle sometimes, it idles kinda funny and sputters a little. I never dies but kinda sounds like it will. What could be causing this? Is like the Idle something control being dirty?

Does anyone have any idea? Maybe the Air Intake Control valve needs to be clean?

clean the IAC ,MAF and check that the EGR valve isn't sticky. It can be cleaned too.

as long as it is o2 sesnsor friendly,yes ... it will say on the back of the can. you can use electrical cleaner on the maf too, but i would just go buy the MAF cleaner.

I wouldn't bother cleaning the EGR valve unless it's throwing a code.

Clean the IAC with anything you like. I've used brake cleaner, carb/choke, SeaFoam, Deep Creep, PB Blaster, Remington Gun Cleaner, etc. I clean mine frequently (still the original). Just shake it dry before you reinstall it.

A sticky EGR would defenitely cause it to do what he is saying, and it's not that hard to take off and clean, maybe 30 minutes and a gasket. And using a product that's not safe for o2 sensors could cause major problems and cost you a $100 dollar sensor instead of just using the right stuff to clean it for 4 dollars..... it's up to you, but i'd rather be safe than sorry. my $.02

1. To remove the IAC valve, first disconnect the negative battery cable, then the IAC wire harness plug

Next, remove the two IAC valve attaching bolts and pull the valve from the intake manifold

2. Disengage the wiring harness connector from the IAC valve.
3. Remove the two retaining screws, then remove the IAC valve and discard the old gasket.

To install:
When installing the valve, always discard the old gasket and install it using a new one


4. Clean the IAC valve mounting surface on the throttle body of old gasket material.

5. Using a new gasket, position the IAC valve on the throttle body. Install and tighten the retaining screws to 71-106 inch lbs. (8-12 Nm).

6. Attach the wiring harness connector to the IAC valve.

7. connect the negative battery cable.

The IAC



If you need pictures, let me know and I'll try to get them to you. This comes from Chilton Online.

Testing

1. Turn the ignition switch to the OFF position.
2. Disengage the wiring harness connector from the IAC valve .
3. Using an ohmmeter, measure the resistance between the terminals of the valve.

Due to the diode in the solenoid, place the ohmmeter positive lead on the VPWR terminal and the negative lead on the ISC terminal.

4. If the resistance is not 7-13 ohms, replace the IAC valve.
