Default Identify this part

This is the mystery part I need to replace, I think. When hooked up to the vacuum on the intake manifold it makes that crazy ticking sound. REmoval doesn't make any noise, doesnt feel different, but IDK.

Anyways, I found the image while searching intake manifold runner controls. The part im referring to is the black bulb on the left side of the intake manifold. This part is on the backside of the manifold, right next to the firewall and has a electrical connector and vacuum hose. The plunger doesnt appear to be stuck or anything, but if it's not an expensive part to replace, then I might as well try.

Regardless of what the part is, how much damage will it be to drive with unhooked like I have been?

best thing to do is block it off, make a gasket out of the blue roll stuff from most autoparts stores. and just don't cut the holes out. Or, unscrew the pipe and fill it full of Black RTV.

The worst thing for the intake is to pump hot exhaust gas into the motor, hot air does not burn as well as cold air. Even with the "unburnt fuel" that it is suppose to carry, I don't think the offset is effective enough.

Why do you think turbos have intercoolers...? Because hot air is no good!

The fuel timing/ratio is set by default to a value that requires exhaust gas to stabilize combustion. Without this process you can get mystery detonation.
So careful about considering it unnecessary!

I doubt that part is the EGR valve. Probably the vacuum actuator for the Intake Manifold Swirl Control.

Well I pluggd back in, my gas is now slighty better, I was as low as 18mpg, not it seems aorund 22 or so, so theres stil an issue.

I did clean the MAFS ealier, so I doubt thats it.

With it pluggd in, it surges, has hesitation, and just sucks to drive. :[

It could be your (iac) valve idle air control, if it's bad that would cause your surging

still no luck. The intake manifold has a vacuum hose near the middle one the outside (driver side) it runs to a connector with another hose that leads to the back of the antake manifold where that black piece is. Transmission is starting to kick like hell now, especially when stopping.

Took it to the local auto store, nothing.

WE searched their databases, books, manuals, other rangrs in parking lots for other reference numbers.

No parts numbers turn anything up, looks like Illl be calling the ford dealer tommarrow, hope they can help me.

WEre having an agreement it appears to be an egr, by function, but the look is like nothing anyone has in stock. :[

Like Bob had said, also could be runner control by the way it appears to be connected to an open chamber across the whole width of the manifold.

Default Re: Identify this part

SCV = Swirl Control Valve.

Intake Manifold Swirl Control (IMSC) is what's on the 2003 2.3L Ranger. It has a vague similarity to the Intake Manifold Runner Control (IMRC) used on some other Ford engines but it is not the same thing.

The electrical Swirl Control Solenoid controls vacuum to the vac operated Swirl Control Valve based on commands from the PCM. There is also a Swirl Control Monitor that reports the movement of the IMSC system back to the PCM for OBDII compliance. Inside the manifold runners, there are 4 butterflies operated by the SCV that close off 60% of each manifold runner to promote turbulance at lower engine speeds and open fully at higher engine speeds for max flow.

and old ford trick to stop idle up/surging.. block the EGR vacuum line with a BB (yes like you shoot in a BB gun) most vehicles the bb is to small to fall into EGR and to large to get sucked thru vacuum line into engine. place BB inside the vacuum line n press conector back on to EGR..

Are you kidding me, cause EGR valves really have vacuum lines and are made out of plastic? Lol Thats the IMSC or IMRC whatever you wanna call it. If the actuator is broken or one of the butterflys are, that would make your ticking sound. I would borrow an OBD II reader (if you can) and find out what codes are logged, if not your pretty much just going to be throwing parts at it. Btw you shouldnt clean the mass air flow sensor, their really sensitive.
