Coming home from lunch just now, I was stopped, and then turning once the path was clear. I got on a little bit (not floored) and then the ESP inoperable light came on. Car just Puts right now. Pressing the gas pedal has no affect at all. I was right up the street so I putted home.

Any ideas on what I can do or check?

I just had 168 pulley, S/C pulley, belt wrap, tune, plugs, TTM fuels rail, new injectors, and headers done about a month and a half ago. Car has been fine other than a little low idle vibration from time to time. I tried to reach Bruce at TTM, but he must be away or something.

have the car read. if a single sensor code is thrown - you most likely have a bad sensor.

if a whole slew of contradicting codes are thrown saying that pretty much anything esp-related is hosed, start by replacing your battery. esp inoperable is a very common side effect of bad/ old battery.

Spoke to Bruce, and he helped me out. Car was idling a little weird, so I was checking the airbox and vacuum lines earlier. Well apparently the little rubber gasket that goes form the airbox into the throttle body came loose, and half of it was sucked into the Throttle body! I put it all back together nice and neat, and it is as good as new now. Thanks for responding though.

Oh, I bought a code reader also.

glad it was something simple.

btw, if you bought a generic odb2 reader it will be severely limited in what it can tell you...
