Question about 1997 Nissan Pathfinder
I own a 1997 pathfinder which has been in and out of the shop a lot lately. 3 weeks ago, i got it back from the shop for having bad overheating problems. fixed that by getting new radiator, thermostat, and gasket. when i drove home that day from the shop,(about 20 miles from home), it drove well. a little transmission bump from reverse to drive, but didnt think anything of it. the next day, i took it to a local restaurant, and while driving out of the neighborhood, it was having some shifting problems like: bumping when it shifts into 2 and 3 gear (automatic transmission). this has never happened before. when i got to about 40 mph on a main road, my rpm went all the way down, and for a split second my car was unresponsive, then shooting the rpm up then back down. my foot was steady on the pedal, but my car was freaking out. if you saw it from a person's standpoint on the sidewalk, my car was lurching back and forth violently. i then let off the gas, and tried again, (take a note that my car was cold, and still hadnt warmed up) only to see it fail again. doing the same violent lurching, i pulled into a parking lot immediately. nothing was going wrong under the hood, i got back in, and it didnt do it again. my car had warmed up. the next morning, cold morning, lurching again violently. and the next morning, and the next morning. thinking my transmission was gone, i took it into the shop about a week and a half after i got it back for the overheating problem.
the mechanic looked at it for 2 days, didnt see anything wrong other than a transmission fluid leak, and i was missing 2 quarts! got it back 2 days later, and drove it off the block cold. it wasnt doing the lurching anymore. however the next morning, it did it again, this time the worst one ive ever experienced. i then went online to look for the same problem. some say bad fuel injectors, but im not sure. by the way, my check engine light has been on ever since i got the car back from the overheating problem
You may need to check your engine coolant temperture sensor may be bad
