2002 intrepid with a 2.7L
I got p0172 and p0175 vehicle maintenance history is had a misfore on 6 had bad injectors and spark was not consistent so replaced injectors coils and plugs and shortly after cam shaft sensor went out whcih was replaced air filter is clean. During inspection i found there is no egr system or plug so i ruled out stuck egr. Check iat and cts both check good on the scan tool seeing the output and using a multi meter. tps looks good nice consistent ouput. Thru the range. I haven't checked the O2's but other than high readings due to the issue seems ok what is the best way to test the O2's and whatelse can be causing this? I am currently checking on a hiss sound but i would like to test the O2'sand anything else lnto ensure i didn't miss something.
