1992 Nissan Maxima 6 cyl Front Wheel Drive Manual
If I push my vehicle a bit harder (130 kph) It runs a bit warmer. This seems to cause a problem with the ECCS or ECU as it limits the fuel. When this occurs, it does not make any difference if you touch the throttle or put it to the floor, there is almost no acceleration. This seems to be causing a lean mixture situation where the engine temp continues to rise. Dropping the speed to 120 or less and allowing the operating temp to drop seems to correct the problem and power returns. The O2 sensor and the cat have both been replaced. Could this be a MAF (mass air flow) sensor failure?
have the same problem?
