    make its way back down to an constant of 1300 rpms when the system was
    checked the reading said the rpm gague itself was going out i replaced
    that and it still has the same code as well as idle/revving high

No, its the intake manifold gasket.  This is a very common problem with the SL/SL1 engine.  There are only three bolts around the #1 cylinder and no bridge in the block between #1 and #2 cylinders.  The flexible factory gasket tends to pull out in this area.
A confirmation of this is to spray some carburetor cleaner, fuel injector cleaner or even WD40 on the gasket around the #1 cylinder and if it affects the idle in any way, its because its leaking.
Felpro makes a good replacement gasket.

DTC P0506

Circuit Description

The throttle actuator control (TAC) motor is controlled by the powertrain control module (PCM). The DC motor located in the throttle body drives the throttle plate. In order to decrease idle speed, the PCM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the PCM commands the throttle plate open allowing more air to pass the throttle plate. If the actual idle RPM does not match the desired idle RPM within a calibrated time, this DTC sets.

DTC Descriptor

This diagnostic procedure supports the following DTC:
DTC P0506 Idle Speed Low

My 2005 altima idles high and engine code


This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set.

Starts/stalls won't run until pedal tapped, 2 miles in town, 6 miles highway, then1000-1500 idle. shut down 9 hours, start/stall tap pedal runs return 6 mi. highway,2miles town same high idle. checked code...


Check your IAC motor (Idle Air Control) It could be sticking open.
Ps. Might be called Idle Speed Control motor it depends on the make and i forget what chevy calls theres.

Fault codes, p0102,p0122,po507


po102--maf sensor, could be a bad air cleaner and not letting air into engine, po122--tps pedal position sensor low, replace or adjust tps sensor,or wiring,po507--idle control system high input. for this you can take off idle air control, and clean out carbon from were it mounts on engine. it is just before throttle body at end of air intake hose, it is black. do not push on pintle on end of valve when cleaning, use a old toothbrush to clean carbon off of valve, use carb cleaner but do not soak valve in liquid of any kind. good luck!!

Check engine light is on and high idle (1500rpm)


Some times the E.G.R. will stick half open. This will make the engine surge or have high idle. Try replaceing the E.G.R. located under the upper intake. Do not go with after market E.G.R. The spring in them are to powrefil and the E.G.R. wil not open. Also try replaceing the O2 sensors. This could give the engine more fuel thus a higher idle. Some vehicles the T.P.S. can be ajusted, do some checking to see if yours is adjustable.

Please contact me if your problem presists.
Thanks, Charlie
