Hey, I've been reading this board all week and it's an awesome source of info. I bought an 88 Pathy 4x4. It failed smog test today(las vegas). I read a few posts on here about it but theres so many things it could be it seems. I'm a novice with very limited cash atm. It failed idle speed co and idle speed hc. I replaced plugs,wires,cap,rotor and oil changed. Also my speedometer is off by 10mph and the trip doesnt work at all, any ideas how to fix that?
