o2 solenoid oxygen sensor

[feras]

hi guys

i wanna ask u about headers

sine i replace my stock exhust to long tube headers and the car is not good

it`s faster and more strong but the rbm is not good i have some hesetation in body and the engine has some cut in rbm

i buy a new oxygen sensore with a new o2 selenoid but still the SES light is on after drive the car to 5 mile

i checked the car with tech 2 tester there are no codes only the Air mass is weak

i think to get back the stock manifold with catalyc converter

what can i do to delete the SES light

what about egr i didn`t delet it

should i delete EGR ..?? or it does not do any broblem .?

Don't understand - if the SES light is on there has to be a code(s) stored in the PCM? What code you throwing?
