Engine Performance problem
2001 Nissan Sentra 4 cyl Front Wheel Drive Automatic 245000 miles
I've been going to my local shop for aprox 2 months now (not a nissan dealership as they charge too much for diagnosis). They have a few ideas as to what they think is wrong with the car, but dont want to fix anything yet just to make sure. My Mech does not want to buy parts that may not even fix the issue.
So. Code read outs are:
too lean (bank 1)
Code 24 (we have no idea what this is as the computer saye " see svc manual" )
and the TPS sensor
Car symptoms are:
I cant accelerate AT ALL.I have to tap the gas lightly to get to 40km/h. Not even the speed limit on the side roads. The hwy-FORGET IT. The engine bogs when giving it gas. If I floor the pedal---nothing goes to the engine. And the engine doesnot even rev---no RPM change. Also, the engine will sometimes shuddler and violently shake when at 2000rpm while driving slow. One day I thought it was going to explode or drop from my car. Thats how violent the shaking was.
What could this be? How can we test the parts without replaceing them. Cause I dont want to purchase parts I dont need!
Urgently needing help!
