CAR GOES INTO LIMP MODE AFTER 15 MILES O

2000 Nissan Maxima

Engine Performance problem
2000 Nissan Maxima 6 cyl Front Wheel Drive Automatic 180, 00 miles

My car goes into Limp Mode-won't go more than 20 MPH. No check engine light goes on. After several minutes sitting it will run perfect. The car runs great for any trip less then 15-20 miles. Any ideas?

Hi DennyNels,

When the engine goes into Limp Mode, some major component is not working and it could be the ECU or bad power or ground connections that deteriorates with heat buildup.

Even though no check engine light has shown, I would suggest scanning the ECM to see if any had been recorded.

If scanning does not fiand any codes, try checking the ECM connectors for corrosion, contaminations.
Also check engine and body groundings.
