| I could not think of a succinct way to word this problem for the thread subject so excuse if it is misleading, but here goes: Day One:
I purchased and installed a brand new OEM Throttle Position Sensor for my 92 TT. Properly adjusted it so I get about .47 volts at idle and the throttle closed switch is on. The car runs like a CHAMP. Color me excited. Day Two:
I am driving down the 99 in Sacramento and the car hiccups for a second. All of a sudden at low speeds when you only slightly depress the throttle (like, 1-2% throttle) the car bogs and looses 200-500rpm, never stalls out, also does not bog if you give it any more throttle than that. On top of that there is no power and it has a hard time climbing over 3k RPM. I figure "new TPS!" so I pull the plug and run the car for a few minutes and let the ECU drop it's old throttle position data. Plug the TPS back in, runs like a boss again. I'm driving it around the block and it randomly just shuts off at a stop sign. After that the same issue (identical) in the paragraph above this one. Go back home slightly pissed, reset TPS again and voila runs like a beast again. Drive it around all night with no problems. Day three:
This morning I woke up, and went out to start the car, did really, really weird stuff on start up with the throttle closed, did ok with it opened up a little bit. Exact same problem as before. No power, slight bog with a teeny bit of throttle. I figured my ECU is being the temperamental wh*&^ she is so I pulled the battery ground and am letting it sit for a few hours. Other than that I'm outa ideas. Any suggestions? Running a custom tune and have a literally brand new harness from Wiring Solutions that was professionally installed at Pitstop Performance. All the voltages look great both in Conzult and with a multimeter.
