hello yall. hopefully someone out there can help me out. I am currently trying to get my 85 ranger smoged. it has a 91 4.0 and manual trans out of an explorer. i am currently getting a code 41 (lean engine condition) so therefore it cannot pass smog. (damn california). it passes the emissions test with flying colors. i have read that it could be the fuel pressure regulator and or the O2 sensor or neither and someting completely different. I am thinking of just replacing the two parts and go from there. im sure they are the originals so it is probably not gonna hurt my situation.
also, it seems to idle high. around 1000 RPM. when coming to a stop at a light or stop sign, with clutch depressed or in neautral, it seems to idle around 1200-1500 RPM. this is continues or about 10-20 seconds after i have come to a complete stop, then the idle drops back down to around 1000 RPM. I have researched the neutral sensing switch that is located on the passenger side of the trans top cover. could this be the source of the high idle. i guess it regulates the idle in neutral vs in gear. not sure why that matters in a manual.
any and all help is appreciated. thanks guys.
