Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Has anything been checked,tested or replaced to try and locate or repair this fault here at all?
Let me know so we can continue,thanks Pete.
One common component I have seen cause an issue like this here is a restriction in the 3 way catalytic converter.This can plug up partially and cause high back pressure causing misfires on all cylinders as well as the rich codes set and hesitation when accelerating.
If you have not had an exhaust back pressure test done this needs done.This is done with a back pressure tester threaded into the pre catalytic converter oxygen sensor port.Your engine is then run at idle to wide open throttle briefly to see if the back pressure exceeds 1.5 psi.If it does at any time then the catalytic converter needs replaced.This is common as I have had to replace several for this fault here.
