ive got a problem ,when driving for about 20 mins the check engine light comes on and the car seems to hold back a little, but then the light keeps going on and off. if i stop the car for 15 mins to cool the lights off again and all ok for 20 mins ,someone said the o2 sensor ?

 

what year and model is it. did you tey a debug the ecu??

 

Read the ECU by connecting the black connectors under the steering column

Come back with the codes.

It could be the o2/Lambda sensor.

thanks for that going to check now

 

from memory 02 sensor is 32, as in 3 long blips, and two short ones

very common fault BTW
