98 Nissan Egr Port Cleaning
I tried a search, and read several threads about this fussy EGR Valve. The troubles this things causes from pollution control (carbon) IS there an easy way to clean.
My check engine light went on yesterday, so I took my car to Autozone and used their OBDII sensor to scan the code for free. The code was P0400 EGR Flow Malfunction..
Ford vehicles with Pressure Feedback EGR Sensors (PFE) or Differential Pressure Feedback EGR Sensor (DPFE), may experience repeated false codes for the EGR system..

Download SERVICE Positive Crankcase Ventilation (PCV) Valve For PCV valve removal, refer to Routine Maintenance of this information. 1. Locate the PCV valve. With the engine running at idle, use pliers to pinch the PCV hose between the valve and the intake manifold. It should be possible to hear the spring loaded valve click shut. 2. If no click is heard, remove the valve from the engine but leave it connected to the intake manifold. A hissing sound should be heard and vacuum should be felt at the valve inlet. 3. If no vacuum is felt, remove the valve from the intake manifold hose. The engine should stall or almost stall. This will indicate a stuck valve or clogged hose. Check the breather hose for clogging or leaks and replace any defective parts.

Download The ball and seat design of the Multec injector eliminates the need of ever having to use an injector cleaner. By design, the fuel metering portions of the injector are not directly exposed to the intake manifold gases that are responsible for the build-up of deposits that can cause injectors to clog. (see Figure 1). Some of these cleaners may contain high percentages of alcohol and other solvents that cause damage to the injectors’ coil wire insulation. Damaged insulation results in low resistance or shorted injectors. Also, alcohol reduces fuel lubricity which increases friction at the injectors’ critical bearing surfaces which results in premature wear. General Motors has conducted extensive injector cleaning studies to determine effectiveness. There is no confirmed evidence that cleaning Multec injectors has resolved a vehicle driveability problem. In addition, suppliers of various injector cleaners may claim that their product can also clean intake valve deposits. General Motors laboratory tests have shown that injector cleaners have little or no effect on intake valve deposits.… Read More
