Recently put Roe HF cats on my GenII.I have put about 200 miles on car since, and I am now getting an engine light,are these possibly related?Anyone else have this happen?

Some folks have this issue with creampuff cars and hi-flows

What year?

Car is a 2001 with no other mods.As of now there are no mufflers/resonators on the car.

yeah... you probably need O2 sims. This has been known to happen w/ the super-sensitive 2000+ computer.

To show my ignorance,what are O2 sims??? I assume this is nothing that will damage the car???

Use the "SEARH" feature for (sims)! A lot of info on the subject!

O2 "sims" are simulators that fool the ECM into thinking that everything is really ok.

Check any of our supporting vendors at the home page under marketplace

The O2's could be a possibility BUT you are guessing! Get a code reader! There are 40 other codes it could be!

Not to mention the sims don't work real well, at least not in my experience ('00 with straight pipes and sims)

 

[plumcrazy]

do you have a code you can post on this ???
