Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.

DTC code 32 is the EGR valve failure, check the vacuum hose and electrical connection to the EGR. remove the EGR and clean it with carb cleaner. After reinstalling the EGR and if the check engine light still on, you may have to replace the EGR valve. Good luck and hope this helps, keep me posted. Be glad to help.

Reset oil change milage

GM OIL LIFE SYSTEM - RESETTING
The engine oil life monitor will indicate when to change the engine oil - usually between 5 000 km (3,000 miles) and 16 000 km (10,000 miles) since the last oil change. Under severe conditions, the "CHANGE OIL SOON" light may be displayed before 5 000 km (3,000 miles). The vehicle must not be driven more than 16 000 km (10,000 miles) or 12 months without an oil change.

Reset the oil life monitor when the oil has been changed, use the following procedure:
  1. Turn the ignition key to the RUN position.
  2. Fully push and release the accelerator pedal 3 times within 5 seconds.
  3. If the Change Oil Soon light flashes, the system is resetting.
  4. Start the vehicle.
  5. The oil life will change to 100%.
  6. If the Change Oil Soon light comes back on, the system has not reset. Repeat the procedure.

Tundra 2007 - turn off "maintenance required" light

Oil Change Reminder Lamp: Service and Repair
Engine Oil Replacement Reminder Light
This light acts as a reminder to replace the engine oil.
This light will come on when the ignition key is turned to "ON" and will go off after about a few seconds.
When you drive for about 7200 km (4500 miles) after the engine oil replacement, this light illuminates for about 3 seconds and then flashes for about
12 seconds with the ignition key turned to the "ON" position. If you continue driving without replacing the engine oil, and if the distance driven
exceeds 8000 km(5000 miles), the light will come on. The light will remain on thereafter.
If the light is flashing, we recommend that you replace the engine oil at an early opportunity depending on the driving and road conditions. If the light
comes on, replace it as soon as possible.
Resetting the system
The system must be reset after the engine oil replacement. Reset the system by the following procedure:
1. Turn the ignition key to the "OFF" position with the odometer reading shown.
2. Turn the ignition key to the "ON" position while holding down the "TRIP METER" reset button.
Hold down the knob for atleast 5 seconds. The odometer indicates "000000" and the light goes off.
If the system fails to reset, the light will continue flashing.

1998 NIssan Frontier service engine soon light at 93,000 miles

that might be a funny coincidence if your buddy knows whats up then it just might be a sensor that would be my guess, check your fuses just to be safe.

Engine light is on oil level is good

Do you mean the Check-Engine light? If so, have the car scanned for codes and post them here and we can take it further. If it's the oil light that is on, you may have a faulty sender. If it's the Service Oil Soon reminder on the info display, that's a reminder to change your oil (which you should be able to reset with the instrument cluster stalks) - that doesn't monitor the oil, but it's a timed interval reminder based on miles driven. The idea is to reset it each time the oil is changed, so that when it comes back, you know to change the oil.
