Periodically my car won't go into second gear. It's like it's stuck and won't accelerate (it revs up but doesn't accelerate or shift to second). I have to pull over, put it in park and then it works. I've had my transmission fluid looked at and they said it was the perfect color and not burnt at all.
Car runs at a high rpm while I am driving and stays that way
A.C. Quit working , I can't find the Low side fill port to add refridgerant.
Please I need hel
It was sitting for a while before I bought it & the guy I bought it from is a car dealer/brake specialist but keeps trying to figure out the issue. The car would run for a good 10 minutes & then start locking.
Fan does not turn on now. Could it be the switch or fan that broke?
My radio, windshield wipers work intermittently. I have to shut the car off and barely turn the ignition to get them to work and when I turn it all the way over, they cut off.
Please help and suggest a repair shop near90004.

Thanks
It's a 1995 nissan 240sx, 5 speed automatic transmission.
seems to be an electrical problem need help
After giving it gas even the windshield wprs cycle and the door chimes, all guages come on, voltage at batt is 11.5, at alt. output is 14.4, also runs shaky after putting it into gear(auto trans)cleaned iacv and other intake components, been on a bunch of forums, this isnt my first car job, so i need some upper tier mech help
I have cleaned the battery grounds and cables before, and the problem stopped. But that no longer fixes the problem
If I let it run at idle its fine but when I rev it up and let off it just cuts off, I thought it may have been because it didn't have back pressure but I put my 3inch catback on it and it helped but it still dies off fuel is good spark is good air is good . I don't know if it could just need tuned or what but I need help
I have to dis connect the ground feom batter before leaving the car
The bracket is attached to the clutch pedal with a pin and cotter pin pin and connects to push rod. It broke and I'm trying to remove bracket it and find one to replace it. Clutch pedal is on floor because of broken bracket. Can't seem to get broken one off.
I have an 1998 240SX SE Auto. Ever since I put 60K miles on the odometer, I've been getting frequent downstream Oxygen Sensor error codes via MIL. The service life from each replacement unit averages 30K miles. Presently, I have 128K on the car.

About two years ago, I had error code for a bad catalyic converter (I believe it was code 420). I had a new cat put in and a vaccum leak addressed. I noticed something strange after the repair, a decreased of 20%-25% fuel economy. I swapped out the air filter, no increase. 2 months later, I get another two error codes for a bad downstream O2 sensor. Again, I replaced it and no increase in MPG.

Present day, I barely passed a section of my smog (ASM Emission Test). HC readings were 57 ppm @15MPH + 30 ppm @25MPH. CA law allows a maximum of 58ppm/42PPM. Technican said it may be a bad cat or o2 sensor.

What is causing this routine failure in my O2 sensors?
Do I need to replace other routine emissions equipment (i.e., upstream oxygen sensor or pcv valve)?
What is causing my degradating MPG?
What can I do to save my replacement cat?

*note: pcv and upstream oxygen sensor have never been replaced.
