Hello...I hope this is the right place to post...I bought my wife a 93 pathfinder SE about two years ago. It has a few problems. I have a couple weeks off work so I want to start workin them out. The big problem right now... Is it don't choke itself when its cold...so you have to pump the hell out of it...I have read thease Nissans don't have a choke and it could be a cold weather sensor...I talked to the smog guy and he said it sounds like a file problem. When I first got the 93...it was winter and it would always start second crank...then it got to where it would still start second crank but chug a little with a little black smoke. Then it got to where it would chug itself out...if you stepped on the gas..it would clear up and would run great after that. Now it won't start on the second crank...you have to pump hell out of it...then it will fire...pump hell out of it...fire a little more..eventually it starts and run good fur the rest of the day...any one know what's up..thank you fur the help..
