Check the EGR air passage tube again.

You may miss some on the first pass.

====


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.


Please rate my answer if it's useful to you.

SOURCE: I want to know the meaning of error code 0077.

The error concerns the intake valve timing control solenoid (VTC). If you have the 16v transverse engine the solenoid is located on the left of the engine at the back of the cylinder head: look at the four injectors at the rear of the cylinder head and then imagine a fifth one at the left and this is the position of the VTC. If has a electrical connector to the top of it and an oil pipe connection to its side. This device is used to adjust the valve timing through oil pressure action on the cam assembly. A high reading (error code p0077) indicates that the 'ground' wire is either disconnected or broken to the VTC. Disconnect the electrical connector and ensure the the the plug pins and socket are free of oily grime or corrosion that might interfere with electrical conduction. Disconnect the negative terminal from the battery before doing such work. When everything is clean reconnect everything, clear the code and test.

SOURCE: my nissan 350z sometimes stalls after starting

after i replaced the battery in my 2003 350z, it would stall immediatly after i cranked it on unless i gave it a little gas. I fixed this by cleaning the MAF and throtle body valve. Total supply costs were $15 and took about 20 minutes. My Z is not only fixed but runs smoother and cleaner.
