Engine problem

Recommended Posts

Hello everyone,

On my 1999 Boxster (2.5, 5speed) I recently disconnected the battery. Upon reconnecting it the car would start fine and idle, but stepping on the gas pedal causes the engine to just sputter and die. After about 5 minutes of letting it run, it will then allow me to rev up the engine (and drive it), although it does still run a little rough. Once the engine cools off, the same thing happens again. Since this happened immediately after disconnecting and reconnecting the battery, I suspect something electrical, although I checked engine electronics fuses and the fuel pump relay, all of which were ok. Oddly, there is no check engine light either, so no P-codes to reference. Any recommendations or insights into what to check next would be greatly appreciated. I just bought some new wheels and now I'm too bummed to put them on. :(

I have been researching my own throttle problem and might have an insight for you. Check your throttle switch as it controls the transition from idle to operational rpms.... there is a calibration/alignment procedure for this that affects air/fuel in relation to butterfly position. You posted this some time ago but I can dig up the information if you still need it. Let me know.
