Isuzu Repair: 2004 Rodeo Stalls/Oil leak, oil pressure sending unit, egr valve

Question
QUESTION: Any idea what could be causing a 2004 rodeo to stall when you slow down to stop, turn or coast?  Also, where would an oil leak come from if it's towards the back of the engine and there are no signs of leakage around the filter?  Your thoughts, please...

ANSWER: Well The oil pressure sending unit could be leaking. Or the valve gaskets. The stalling could be a fault in your fuel system or a faulty loose main ground wiring harness that is a huge problem with Rodeo's. Although I would check both your fuel system, and your ground and if that is not it we will go from here okay?

QUESTION: This information is a great start!  Thank you so much for your rapid response.  Can you tell me where the egr valve is located on the 2004 3.2l engine?!?!  We've found it extremely difficult to find any information.  We've been advised to try to clean it, but cannot locate it.

Answer
Top left rear hand corner of the engine(passenger-side). It is a cylinder-like object with an electrial connector plugged into it. It will be bolted down with two(maybe three bolts). DO NOT USE CARB CLEANER to clean this!! Use a soft wire brush. The carb cleaner with permanently damage the valve.
