Help! limp mode after turning - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I got a stock 92 s13 hatch with ka24de.

I got the car running and everything worked great for about a week. Went for a cruise today and noticed weird bogging after turning sharp right...would drive without a problem on the streets but once I got onto the on-ramp, engine wouldn't pull past 2500rpm. Had to sit for awhile to get it up to 70mph.

I noticed my rpm go up and down about 500 rpm at idle in neutral.

Anyone had this happen to them and know how to fix this or where to look? Much appreciated

Not sure but sounds like aicv? Vacuum leak it can b a good amount of things honestly
Start by testing the maf with a multimeter

The 2500rpm thing sounds like the maf. You said this is after turning a sharp right? How low is your car? If low enough you prolly rubbed through the harness in the wheel well. Pull off the fender and take a look.

What he said. Op thanks for a Good accurate description of what you were doing when you noticed. Definitely sounds like something rubbed though. Was there any bumps in the hard turn?

I don't think anything rubbed through the harnesses, I'm not that low and harnesses are both tucked away.

I drove it around again today and after some time driving around, it started doing the same thing. But now it won't go past 3000rpm., shakes and wants to die at a stop. Sounds and feels like complete crap...
