Hey all, I have a H22a in my firends 94 Prelude. My problem Im having is sometime, well most of the time between 2-5k rpms the car is hesitant. Sometimes it works great, sometimes its super sluggish. And after about 10 min. of driving the check engine light will come on. I want to check the codes but once the key is turned off and turned back on the light goes away. Could that be a faulty 02 sensor causing my problem????

 

possibly a bad cat
