dropping rpm issues
 

Yes I searched!

Got the Z finally running and registered. Now this only happens sparatically so I'm not sure if its a fuel mapping in MS or something more serious.

Issue is I was driving to work today when I came to a red light the rpms in neutral would drop down to around 400 and then back up to normal. Every once in a while it dies completely. I have checked all grounds and fuel pressure which is good. When actually in gear and on the move I'm not having any flucuation or anything abnormal.

That makes me think that it might have to do with something in megatune aka accelleration wizzard or ??

Right now I'm just using the MAP for throttle and not the tps (240sx), can't seem to find the tps wire. (i just see the vref and tps return) Can that be the issue? Also I have no vaccuum leaks so I know I'm good on that end. Its nice having just 3 vaccuum hoses.

From my recent nightmare w/ TPS's, that could be a possible problem, tho I'm not familiar w/ the MSnS tunes. Hook up a lappy & see what's going on.

I believe MS will tell you if the tps goes out of spec. My experience with tps failure is it's usually at low throttle. That said, nearly every parameter setting in MS could cause something like that, so I'd be checking out my settings before I went to replacing parts.

Thing is i'm not using tps right now just my map sensor which pulls from vaccuum
