After swap questions
swaped a '00 B16a2 in my 97 hatch, running obd1 ecu, runs perfect...ran open header for 2 days, CEL goes on...throws code: 01 (o2 sensor), and code 14 (iacv)...bolted on '00 Si cat, stock DX piping and DX muffler, CEL went away...today i drove around for a while, was hot (not sure if this matters and sat in traffic a lot) CEL went on again...same codes as before (01 and 14)...came home shut off car, started again, CEL was gone...let it idle for 4 minutes, still no CEL...drove around tonight for 30 minutes, no CEL...my question is, why does it throw CEL's every once in a while? could my IAVC be bad? am i running too rich that it would trip my o2 sensor? running open header gave me no backpressure, now does a stock DX exhaust set up give me too much back pressure? is this something to worry about...also when the CEL goes on, the car idles perfect and runs perfect...any and all help is appreciated
