Probably the idle air valve on the passenger side of the throttle body. It's about a $40 part and simple to replace.

My 93 ford f250, 7.3 IDI sounds like a rod is knocking when I first start it up but after it warms up it sounds very faint. What could be causing this noise?

The 7.3 idi engine is a compilation of ford and international engineering with a compression ratio of 21.5:1 ratio and produced 338 ft/lb of torque @ 1400rpm
It is an indirect injection engine (IDI) and the noise could come from a cracked pre-combustion insert that expands on compression heat and so reduces in sound. It may also be a faulty injector tip that is squirting rather than atomizing as it should
I would remove the injectors and have them tested at an accredited diesel repair specialist before going any further. Talk with a service centre for advice on the insert but as they are normally covered partially by the block there is a risk that they may come out or disintegration but it needs checking out.

I have a 91 f350 7.3 liter idi. It will not start

cranks ok , and fast?
after checking all fuses. (the FSM shows correct fuse)

International Harvester IDI (from Indirect Injection) engine is a 4-stroke 8-cylinder Diesel engine used in International Harvester trucks,
like all diesels check fuel filters first. (service)
then make sure glow plugs work. (fsm covers this)
then scan it EFI for DTC errors. got errors?
direct injection uses EFI.

IF DIY, you need the book, I promise.....
its not simple like old diesels were.

My car will not run or starts and will not take the gas when it rains or damp outside. when it sets a day or two then runs great. What can it be. I was told it can be a module. Which one. yes 1996...

If your car is equipped with a 2.4L Quad 4 engine, you most likely need to replace your ignition coils. They are located inside what is called the "IDI Module" This is the large cover on the top of the engine that says "Quad 4". The ignition coil housing and spark plug boots should also be replaced. (See pictures below)

To replace the coils, disconnect the IDI electrical connector (Driver's side of the IDI Module) Remove the 4 bolts retaining the IDI Module to the cylinder head.

NOTE: be careful not to loose the washers under the bolts. Sometimes they will stick to the IDI Module and will fall off when you remove it. It is best to take a small screwdriver and get them loose before they have a chance of getting lost. Trust me...It happens all the time.

Remove the IDI Module from the cylinder head and flip it over. Remove the 4 screws holding the coil housing to the IDI module and remove the housing. Remove the screws holding the ignition coils and remove the coils. Reverse procedure to install.

I have an Oldsmobile Alero GL 2003 & I'm not sure what size the engine is. I needed to know how many plugs are in it & the mechanic told me it takes boots not wires.

if the engine says its a 2.4. then it is a 4 cylinder ( 4 plugs ).on the 2.4 remove the four bolts on the ignition coil cover. pull the idi cover straight up until the boots are off the spark plugs, then set cover aside. if the boots stick to plugs, you can reatach them to coil cover on bottom of idi cover. thats it !! have a good day !!
