Nissan Sentra SS 91 Problem

[chizcake71]

Help Please! Bumababa yung idling ng sentra na ito. Pag-nagpreno ka, babagsak ang idling at mamamatay ang makina. Di pwede bitawan ang accelerator, kung hindi, mamamatay or sobrang baba ng rpm. Anybody has any idea what could cause this problem? Automatic 1991 model nissan sentra. Anybody encountered this problem and successfully resolved it?

Although i dont have any nissan background, you might want to consider checking if nissan has what we call an idling servo that controls the idling within 800-900rpm.

good luck.

It's a common problem on ageing Nissan EFIs (as well as with any ageing EFI vehicle).

Do first the following:
- tune-up
- intake plenum/manifold cleaning
- AAC valve cleaning (Air Actuator Control)
- MAF sensor cleaning and reground (Mass Air Flow); have a Nissan CASA check if it's calibrated properly through their CONSULT computer.
- Change your high tension wires if (spark plug wires) this had not been done in over 5 years.
