Tonight I went to start my car (it started), it reved a bit (as it usually does), ran for a moment (that is the point right), then died.

I lathered, rinsed, and repeated a few times, but no change.

I found that if I feather the throttle a fair bit, it will stay running so long as I play with it.

I've got a CEL now, but EvoScan doesn't give me any codes. I did a datalog and compared to previous results. What I found was that my TPS doesn't report anything but 99%-100%, my O2 sits at .02 (which might be fine because the car is soo cold, but I've never logged in these conditions), and my Accel Enrichment stays at 100 (as do many other parameters that normally fluctuate at least a bit).

Back to the TPS: With ignition on, and engine not running, I logged for some time and found that the TPS does respond predictably, but only scales from ~99% to 100%. It will not go lower. When I say predictable, I mean that if I don't touch it, the TPS will report ~99%, but if I put it down even say, 25%, TPS shows 100%.

Anyone heard/seen this before? Ideas what might be going on?

Tommorow I will give the dealership a call, but I want as much info as possible in case they try to get slippery (i've NEVER had to take any of my 3 Lancers in).

Is your car modded? Did you flash the car yourself?

 

Right now it's stock. No flash, no mods (unless you consider a drop-in air filter, wheels, and tires modded). I'm hesitant to mod because it is my daily and I'm paranoid (anyway, it's pretty much a bad-a$$ car as-is).

 

If you are still under warranty just take it to the dealer.
