Smashfinder Posted January 12, 2007 Share Posted January 12, 2007 (edited) ok, problem... for a while now 92 pathfinder, 5-Spd XE, 250Km on Odometer. VG30E - MPFI Intermittently runs like crap. Feels like a V5, or sometimes less. In some cases, can stall when Idling. Lots of gas smell, and white smoke. Havent found a trigger yet, but it started after some 'in the water' time. That was months ago. I can get the vehicle to run a bit better with mass amounts of Injector cleaner, but even then... While Ive been troublshooting, weve been gettin a lot of wetness on the left coast, so the water may be a factor. Ive replaced the sparks, and wires, and distibutor cap, and of course fuel filter. tried to reset the ECU a few times, but doesnt seem to do much. Also, the timing belt is only 6 months old, and the air filter is clean. again, the problem is intermittent, so, maybe an injector that is partially clogged.. My mind, with some assistance, has come to some possibilities: -fuel injectors-plea$e no -air intake leak -ehaust manifold leak and/or o2 sensor -head gasket maybe -Water in the Fuel tank, or possibly the fuel pump itself.. Anyone had this problem, or have a suggestion? She's driving me nuts! Oh, and if anyone saw on my intro, I had a problem with the Calmini steering kit, but it was the wrong Pitmann arm. Calmini is sending the other one free of charge. sweet. I really cant wait to get that in there... Thanks for the advice on the steering kit Edited January 12, 2007 by Smashfinder Link to comment Share on other sites More sharing options...
unccpathfinder Posted January 12, 2007 Share Posted January 12, 2007 possibly the rotor is worn on the ends and gets some surface rust on it if its moist out and sits overnight? Link to comment Share on other sites More sharing options...
Smashfinder Posted January 12, 2007 Author Share Posted January 12, 2007 ill check the rotor. i dont remember it looking bad when i did the dist cap. It does sit overnight, and yeah, rust happens a little more than I'd like to admit Link to comment Share on other sites More sharing options...
88pathoffroad Posted January 12, 2007 Share Posted January 12, 2007 Clean your MAF sensor and make sure the wiring is in good shape and plugged in all the way. Link to comment Share on other sites More sharing options...
wheel366 Posted January 12, 2007 Share Posted January 12, 2007 I had that problem with it stalling and smoke but it wasn't intermittent. My distributor gear broke and my timing was off. Maybe your timing belt is slipping. Link to comment Share on other sites More sharing options...
wheel366 Posted January 12, 2007 Share Posted January 12, 2007 If there is water, put some water remover in like dry gas. Maybe 3 - 4 bottles. Also, check your plugs. Link to comment Share on other sites More sharing options...
BLouisGod Posted January 12, 2007 Share Posted January 12, 2007 That fuel smell and lack of power is from a fuel injector dumping. Its having trouble opening and closing and is on its way out and is just flooding the cyclinder at times. This happened to my gf's v6 cougar - Id take it to a shop to get a Dx.

Spooled Posted January 13, 2007 Share Posted January 13, 2007 Have you tried running a diagnostic on your ECU to see if it throws any codes? That would help narrow it down. Also - check all your connectors, especially the fuel injector connectors, MAF connector, and O2 connector. They can get corrosion in them and cause a bad connection.

Smashfinder Posted January 14, 2007 Author Share Posted January 14, 2007 wasnt the distributor rotor. Was hopin it might be. I did get a good price on the injectors though, so im goona put those in when i get em. i couldnt get any codes from the dealership, cause every time the truck getrs near there, she starts runnin fine i will clean the MAF sensor before i buy the parts, but im really leanin toward the injectors. Ill do the O2 sensor for good measure I lean toward the injector, because when i swapped the plugs a few weeks ago, one was covered in soot Link to comment Share on other sites More sharing options...
Slick Posted January 14, 2007 Share Posted January 14, 2007 sounds just like when my head gasket went out..... very little smoke, power loss, gas stink....... thought it was my injectors and it was actually a slightly broken piston and a HG gone.
