dirk Posted May 16, 2010 Share Posted May 16, 2010 Well i'm definetly getting to the point of pushing my pathfinder off a cliff. This is the problem after hour of driving I turn off the ignition and turn it back on and boom thing sounds like crap! and the tac is vibrating like crazy and the exhaust is super loud. Sounds like its not firing correctly but it only happens once its at opperating temperature, and it doesn't go any faster then 10km/h. Replaced the MAF with a new one, brand new ECU temp sensor straight from the stealership, new cap checked every spark plug cable they all read fine, coil reads fine. checked the ECU for codes only gives me the normal opperating code. Havent tried replacing the o2 sensor but could that be the main problem of all this? Then once I let it sit for an hour or two its fine to drive till it warms up again.

Daves94XE Posted May 17, 2010 Share Posted May 17, 2010 sounds to me like the catalytic converter is stopping up. when it does it get out and look at the cat. if it is stopped up the cat will be glowing red. Link to comment Share on other sites More sharing options...

edicer2 Posted May 17, 2010 Share Posted May 17, 2010 does it smell really bad? like rotten eggs? Link to comment Share on other sites More sharing options...
dirk Posted May 17, 2010 Author Share Posted May 17, 2010 I haven't really noticed but i'll check it out. Should it stink bad even for the first time I start it or only after i've driven it and it starts to crap out? Link to comment Share on other sites More sharing options...
ZombeeXXX Posted May 18, 2010 Share Posted May 18, 2010 It's most noticeable after several minutes under load, say, on the highway nice and warm and then you stomp on it.. But then only the people behind you really smell it. Link to comment Share on other sites More sharing options...
dirk Posted May 19, 2010 Author Share Posted May 19, 2010 I didn't really smell anything but I took the cat off anyways lol noticed more power but same problem is occurring! And it seems like its starting to crap out faster and faster each day. i'll be driving at 50km when the problem is starting to happen and i'll floor it and it just gets loud but doesn't drive any faster.

Kittamaru Posted May 19, 2010 Share Posted May 19, 2010 Possible that the ECU is bad? I dunno, grasping at straws here - someone had this issue before IIRC, but I can't think of their name else I'd look it up for ya Link to comment Share on other sites More sharing options...
dirk Posted May 19, 2010 Author Share Posted May 19, 2010 So I changed the o2 sensor with a brand new one same issue but its not as bad. Is it possible the timing belt is off? I guess that will be my next straw to grasp..... Link to comment Share on other sites More sharing options...
dirk Posted May 22, 2010 Author Share Posted May 22, 2010 Okay so I grabbed a ECU from the scrap yard, off the same pathfinder and now the ECU is giving me a code and its code 35 I think the one to do with the detonation sensor, could this be the whole cause of my problem? Or is this ECU just storing an old code from the previous pathfinder? Link to comment Share on other sites More sharing options...
Precise1 Posted May 22, 2010 Share Posted May 22, 2010 I don't believe it is possible to store a code from another vehicle after being unplugged, but part of the checking for codes tells you how to clear them, sooo, clear them and try again. Sounds like you are onto something though... B Link to comment Share on other sites More sharing options...

B Wow I am totally pissed, so I attempted to changed my knock sensor and my bloody pathfinder doesn't even have a knock sensor its just a freakin rusted hole! I took apart the whole intake manifold for nothing sweet... and there isn't even a cylinder head sensor just another rusted hole! k death to pathfinder.
