I just put in some catco cats, for 2 years I have run hollow stock cats. Started the car after disonnecting the battery for a few minutes to find the check engine light came on. Now prior to gutting the old cats 2 years ago, I never had check engine light on, just wondering if the o2 sensor(s) needs to be replaced. Car runs fine but I need to get it inspected and was wondering if this is going to impact the readings.(N.Y.)

I hope someone can give me a quick answer, and if I need the sensors how much are they going to run me? Car is a 91

Thanks!!

Sensors will run around $90- $100... bosch 02 sensors like $45 each.. not sure about your problem , best bet is to

" GET THE CODES READ :) " and im sure everyone else will tell you that.
 
i had a slight exhaust leak where the pipe hooks to the manifold made my lite come on , i tightened all 6 bolts again and it was fixed , also if you have egr make sure the hose is hooked up from the exhaust pipe to the transducer
