pathlesstaken Posted August 12, 2011 Share Posted August 12, 2011 Having some problems with the 03' 3.5 R50, and wondering if anyone else has had similar issues. First, the vehicle will stall when the engine is warm. This has been happening for 6-7 months, and was worse before I cleaned the MAF. I haven't had any problems since last year/ earlier this year but last night I watched the tachometer jump up and down after I hit the gas. There was a corrosponding power loss, but no stall or light. Today, I tried revving the engine when it was cold, while driving, same thing happened, now with the Service Engine Soon light on solid. The Pathy does this when cold or warm, up or down hill, I'll be getting the codes later today. Any thoughts? Link to comment Share on other sites More sharing options...
fleurys Posted August 12, 2011 Share Posted August 12, 2011 most probably MAF... they all (01-04) eventually fail... the symptoms are pretty much it... search for the maxima maf hack that will save you a couple of hundreds... S. Link to comment Share on other sites More sharing options...
Towncivilian Posted August 12, 2011 Share Posted August 12, 2011 If you need a MAF, use this part. Identical to VQ35DE on Pathfinder's MAF and way cheaper. Link to comment Share on other sites More sharing options...

S. It's not the MAF, it's the swirl valve control solonoid. P1130. fffffffffffff..... Link to comment Share on other sites More sharing options...
fleurys Posted August 13, 2011 Share Posted August 13, 2011 I greatly doubt a defective swirl valve solenoid will cause the issues you're having... hopefully others will chime in... Link to comment Share on other sites More sharing options...

It's the only code coming up. Also, that solenoid controls the swirl valve specifically between 2400 and 2800 rpm's. That's exactly when the tach starts jumping and I start losing power.

Towncivilian Posted August 13, 2011 Share Posted August 13, 2011 Check the vacuum hose for the swirl valve actuator, it may clogged with carbon or something. Link to comment Share on other sites More sharing options...
