flight4 Posted September 5, 2006 Share Posted September 5, 2006 74k miles, V6 engine, automatic. Had the truck for 3 years. Now suddenly having stalling problems. Fuel smell... engine runs rough, then stalls... 5-7 mins later will restart as if nothing happened. During the last waiting period, I tried to start and found that the only way the engine would even think about firing was if the throttle was WIDE open.... Heavy fuel smell... Waited the extra 5 mins and it started up. Link to comment Share on other sites More sharing options...
k9sar Posted September 5, 2006 Share Posted September 5, 2006 74k on an 89??? wow. Did the PO forget how to drive? My first thought is to check your fuel filter. Link to comment Share on other sites More sharing options...

flight4 Posted September 10, 2006 Author Share Posted September 10, 2006 Followed the link to get the ECU codes... Worked well. I have an error 21, ignition... So will be looking at that early next week. Thanks for the help, much appreciated..... Pity I cant get more HP out of the engine, no emission testing here and fuel is running at about 75cents a litre for premium! I just cant find people to do the work and get it right first time!

88pathoffroad Posted September 11, 2006 Share Posted September 11, 2006 Typically, the O2 sensor going out will make it run pig-rich like that. The mass airflow meter will too. Sometimes it just doesn't give the ECU enough trouble to throw an error code for it. Link to comment Share on other sites More sharing options...
flight4 Posted September 14, 2006 Author Share Posted September 14, 2006 The Nissan dealer in Buenos Aires would like to charge me US$1,300 for the ignition coil and module... 50% up front and then a 60 day wait for them to arrive! So I have sometime and a bit of a budget if I am going to purchase direct from the US, which is what I will do. I had the Oxygen sensor changed only two years ago, can they go frequently? Same for the Mas air? If I am going ahead and purchasing coil, module, O2 and Mass, can anyone advise brands? If I spend more, will I feel any difference in performance? Thanks!

flight4 Posted September 14, 2006 Author Share Posted September 14, 2006 One more thing..... I have automatic transmission, which jolts when changing gear at low speed.... It used to jolt all the time until I had the transmission oil changed.... What might I have to do to smooth it out? Thanks. Link to comment Share on other sites More sharing options...
88pathoffroad Posted September 15, 2006 Share Posted September 15, 2006 $1300 for a coil and power transistor is robbery. Are there no parts stores that can ship internationally for less? Try cleaning the MAF first. It takes 5 minutes...there's a thread in the Garage forum under How-To's that tells you how. Link to comment Share on other sites More sharing options...
flight4 Posted September 15, 2006 Author Share Posted September 15, 2006 I will be able to get a coil and PT sent from either the US or I will pick one up in Beirut when I go back there. The other side of the coin of course that although somethings here in Arg are extremely expensive, everyday living isnt! I will get the MAF cleaned and see what happens..... Being very careful with those wires, eh? The O2 sensor.... If that had gone, it would be drinking fuel.... And I am still suspecting the coil. The touble seems to happen in very cold weather, which we have had recently, so maybe I will put the coil in the freezer for a couple of hours to see what happens! Thanks.

flight4 Posted January 21, 2007 Author Share Posted January 21, 2007 Well guys I am back, and still with the same problem. I have replaced both ignition coil and transistor units (arrived at about $400!) Engine stalls and then restarts again 3 - 5 mins later. It can also run rough sometimes. Finger pointing at heat/temp sensor, but then this is intermittent, and my mechanic cant catch it out even when trying all day. Stuck injector???? Anyone any bright ideas? Otherwise its 2 months off the road for a rebuild. Oh and the MAF is very clean!!! HELP! Link to comment Share on other sites More sharing options...
unccpathfinder Posted January 21, 2007 Share Posted January 21, 2007 have u checked the simple things...plugs/wires/dist rotor/dist cap/air filter/fuel filter check the O2 yet? possibly disconnecting it and try to crank the truck it should run up to somewhere on the RH side of the engine bay if u follow the wires up Link to comment Share on other sites More sharing options...
88pathoffroad Posted January 22, 2007 Share Posted January 22, 2007 I just read a post where the distributor was causing the same kind of problem. They're expensive, though. I have two or three spare *used* distributors in my garage. If you can, try and find a shipping cost from Salem, Oregon USA, zip code 97301 to Buenos Aires, or wherever you'd like it sent. I can send you one for $20 plus the cost of shipping. If it doesn't fix your problem, at least it was cheap enough to have on hand for later, right?

NissanPerson Posted January 23, 2007 Share Posted January 23, 2007 Did you try cleaning the injectors? Sometimes it's a simple fix. I know mine used to love it when it got its injectors cleaned. It'd do crazy things like you're describing then stop after an injector cleaning. Otherwise 02, mass airflow, water temp sensor, throttle position, fuel filter, and everything else that's been mentioned. It's just a crap shoot at some point.
