I picked up a new throttle body for my 99 Durange 5.2L. The screw holes for the MAP sensor are present but not threaded.

Why I would like to replace the throttle body is a long story, but my question is has anyone any recommendation for safely threading these screw holes?

Thanks...Dale...

 

Take it back!

If you want a new TB why not just upgrade to a www.thefastman.com 52mm TB?


If you are really wanting to "Fix" this broken TB then I would say ensure it is drilled to depth then go ahead and thread it with the bolt you plan on using threading. But do this off the truck!

 

I'm interested in why he's replacing the throttle body!

 

And hydra, u might have the answer to this, why aren't the holes threaded? Is that factory?

 

Thank you for the info.

Throttle body's are not availble from various dodge part stores I have checked, at least ones that do not require nods.

I picked up a holly from ebay. The screw holes for the map sensor are present but not tapped, hence the question.

I have been tracking down an occasional hard start where I have to hold down the accelerator to start the car. In this case it won't hold idle until it warms up.

Now, before folks start suggesting IAC and TPS (which have replaced twice), the car was at a local repair shop and dealer for a month and could not find the cause. This is some nonstandard issue.

I believe the IAC valve is getting stuck in the throttle body at the opening. The valve contact point is a vary narrow almost a line wide. Other throttle bodies i have seen appear to have a wider contact with the IAC valve.

I have replaced:
PCM
Camshaft position sensor
Crankshaft position sensor
Plugs, wires, cap, rotor, coil
Fuel pump
Injectors
Map sensor
Throttle position sensor
Ambient air sensor (manifold temp also)
Coolent temp sensor
Plenum gasket (had that issue previous)
O2 sensors (up and down stream)
Various relays
Alternator

No code has ever been thrown. Runs great otherwise.

If I manually move the IAC open, the problem is fixed until next time.
