Car runs better with no TPS!?
My car is back to its old tricks. Extreme bucking under acceleration. Stomp the gas, RPM's stay locked at whatever RPM I'm at, than *maybe* all of a sudden rev up like crazy. I have no idea wtf is going on. So I disconnect the TPS, which is brand new, and the car runs and drives almost like normal. explain.

Similar issue on my S13 (not nearly as severe, though), and it's a random thing. Happens every once and awhile, but never happens if the TPS is disconnected...
I've tried MAF cleaning, new plugs and wires, checked all the other likely culprits...to no avail. I actually get better gas mileage with it unplugged, so I leave it that way. Haven't tried a known-good MAF...and that's the next thing I'll do...as the MAF and TPS work together when the ECU is in closed loop. - - - - - Anyone know what the ECU defaults to with no TPS input...back to the "maps"...? - Brian |

interesting point on the, it not being set thing, but the car ran great for about a month. will try the O2 thing after I reconnect the TPS.

I bet you something (wire going to, or plug) on the TPS is fucked! Or you could have a bad ground. Dam nissans are notorious for those things.
