Engine Performance problem
2001 Nissan Sentra 4 cyl Front Wheel Drive Automatic
Hi, I have a Nissan Sentra that has some issuse. The only code is for the transmission first gear- due to the hesitation of the motor.
When I started the car it idled fine but when I hit the gas it would hesitate or try to stall out. I cleaned the mass air flow sensor, checked the vacuum lines, and tapped the throttle positioning sensor with a wrench. - Then it seemed to run just like new -
On the test drive I went to wide open to get on the highway and a few seconds later it stopped accelerating then surged real bad till it stalled out. I was able to drive home barely at 40 mph. Now if I hold the accelerator it surges constantly and wont hold a steady rpm or it stalls out.
What happened? It went from bad to great to realy bad. Did the throtttle positioning sensor break? Could it be the ignition module?
have the same problem?
