Nissan Repair: 1996 Maxima, nissan maxima, cold weather

Question
Hi,

Over the past couple of years, the check engine light on my 1996 Nissan Maxima has switched on and off in hot and cold weather.  The car, until recently, has been running fine.  My mechanic checked the codes and they were speed and communication sensors.

The car has stalled 1/2 dozen times a day for the past 5 days.  Before that 3 times over a ten-day long period.  It takes 4 tries before the engine turns over, but it's always started again.  Once the check engine light came on and it was a communication sensor.  The mechanic suggested replacing the car's computer.

Soon after I bought my used 1996 Nissan Maxima in 1998, the tachometer got stuck at 8000 RPM.

Any ideas what the problems are?  Are these problems related?  

Thanks.

Leila,

The computer could have a bad connection and it is possible the computer could need to be replaced.  However, I would have the mechanic disconnect the computer and reconnect it to make sure the connection is seated properly.  Drive it for a couple of days to see if this corrects the problem.  If not replace the computer.
