VERY interesting ... Rodney2764,
I HAVE seen similar issues before...
Everything else seems to be good. I would be
thinking about having an EXHAUST shop look
for a loose MUFFLER baffle or collapsing
CATALYTIC CONVERTER...
A rusted or loose part inside can COMPLETELY
block EXHAUST OUTFLOW...
It is not a COMMON trouble... but certainly worth
the look (while you are mobile (my opinion...
RATHER than WASTING time & money
buying A WHOLE lot of UNNECESSARY oxygen
sensors ( get mistakenly replaced )...
(( from "FREE" code readings )).
((( really difficult to resolve when you are immobile ))).
Hope this helps...

SOURCE: 98 Isuzu Trooper stalls on cold start, idle issues..
I had the same issue on my 99 Trooper.
It would usually start when completely cold, but idle around 2k RPM.
It would drive fine. But if I shut it down, ran into a store, and came back out, it would start but immediately idle.
Had to ride the gas a little to get it into gear.
The Check Engine light has been going on and off for 6 months or so.
I took this to my local trusted repair shop (no Isuzu dealers within 200 miles).
The diagnosed the light, and found that the Intake Gaskets were bad or leaking.
The idling problem was related to the car not being able to control the amount of air coming in.
They replaced the Intake gaskets by the next day, and I haven't had a problem since. And no more check engine light, which has been on half a year.
Here's some details from my bill:
(1) Intake Gasket set $107.95
Misc materials $21.00
2.1 hours of Labor
The total cost to me was $345.00, and I definately don't feel gipped.

Crankshaft and Camshaft Position Sensors
Camshaft Position Sensor
Engine timing is determined from the relationship between the crankshaft and camshaft. This relationship is maintained by a timing chain or timing belt. The Engine Management System does not control engine timing but it does monitor the relative position and speed of these shafts by monitoring signals generated by sensors. The Engine Management System (EMS) uses signals generated by the camshaft position sensor to synchronize fuel injection to the valve sequence and for the on-board diagnostic procedure for misfire detection. The EMS energizes the injector at or near the time the intake valve opens. For misfire diagnosis, the EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses Diagnostic Trouble Codes (DTC’s) should be stored in the EMS.
If the camshaft position sensor or circuit is faulty most engines will start. Some engine management systems will then default to a pre-programmed injector firing sequence. All injectors may be energized simultaneously or all of the injectors on one bank may be energized at the same time. If the CMP data is required for misfire detection and reliable CMP data is not present misfire detection would probably be suspended.

The following symptoms can be caused by an intermittent wiring connection or faulty signal to the EMS:
Crankshaft Position Sensor
Engine speed is a very important input to the Engine Management System (EMS). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, hall-effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is located in close proximity to the crankshaft.
In addition the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.

No Start/Intermittent Start Condition – Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit
SOURCE: car makes a metal grinding noise at idle
sew them. something is stuck did you turn or anything in the wash?
SOURCE: The RPM of Nissan Altima stays high when drive over 65 MPH.
No....the rpms differ from engine to engine and from manufacturer to manufacturer. RPM's are always higher at higher speeds.

2002 nissan altima, accelerator , gauges, and power steering stops working. Engine continues to run and radio is working. Pull over and stop, then restart car and it runs fine for a while??
