95 MAXIMA ROUGH IDLES DIES

[asp338]

The crank pulley went out a few weeks ago and I changed it and both belts. The car sat for about 2 weeks before I could get time to fix it. It ran fine before but after changing the pulley and belts it doessn't want to idle at times. I checked and there are no codes. The car has 165K and had no problems before this. Now it starts perfectly and runs fine, except when you stop. The idle will drop down to 200-300 rpms and the engine will sometimes die, other times (rarely)it will idle just fine. I have run a can of seafoam to clean the feul injectors already and it didn't help. Suggestion? Ideas?

Welcome to NICO.

Check the entire air intake - check/replace the air filter, clean the MAF sensor and connector (CRC MAF sensor cleaner for the sensor and Dielectric grease for the connector) and clean the Throttle Body (never spray 'carb' cleaner directly into the TB, use rag)(. Most likely dirty IACV is causing the idling issue (cleaning procedure available in the 'sticky' - "The most Important...").

Also check/clean the main engine harness ground points (2 ea, adjacent to intake plenum, near Cylinder #2).
