Engine Mechanical problem
1990 Nissan 300ZX 6 cyl Two Wheel Drive Manual 40000 miles
I have a 300zx twin turbo and the problem is it will not rev over 3500rpm and I can barely get up to 40mph. It is not giving a check engine light but I had it checked anyway and it said problem with right o2 sensor, it is reading back and forth between rich and lean and said to check for vac. Leaks. Could this cause my car to run this way.
ps. That is the only problem the scanner showed, everything else check out
