Alright, so I've got 56,xxx miles on the odo. The car started slipping on the backroads, very unsettled shifting, at one point the car almost stalled. I had to take it home so I got on the highway and at that point when I tried to very slowly accelerate to highway speeds, my SES, TCS and SLIP lights came on. The car was very hesitant and wobbly all the way up to 60. As I accelerated further, I noticed that I was unable to accelerate any faster than 66 MPH, at that speed the car would buck slightly and the tachometer would jump slightly, but very repetitively. I finally got it home. Its parked outside now and I'm debating whether or not I should remove my Skunk2 Plenum Spacer before I have it towed up to Nissan. What do you guys think is the problem? Also, do you think I should remove the spacer before it gets to the dealership, or will they not have a problem?

I would remove it just to be safe. You do not want them to say warranty is voided due to aftermarket parts and abuse. I am not saying you abuse the car that is just what they MIGHT say, so to be safe remove it. Let us know how you make out.

 

definately remove the spacer. should only take an hour or so- not worth the risk to leave it on.

 

yeah, no, I completely understand that they would say that I'm abusing my car. I'm going to remove it I'll fill you all in.

could be your torque converter, my civic had the same problem (auto tranny slipping in 3rd gear) and it soon blew out... found out my torque convereter went boom.
