Default What did i do?

Okay..on my last install job, i had to tap into the ecu wire that sends the throttle position. I accidentally grounded it while the car was running and did not relize it until about 5 miles down the road. I corrected this problem and everything went back to normal....Now sometimes my idle is a 1700 and then it settles down to its normal 700...what did i do...did i fry the sensor???
any please help.

I'm already throwing a code CEL for a bad front o2 sensor which is getting replaced next week.

If your front o2 sensor is bad the car won't idle right. When mine went bad it was the heater core that heats up the sensor to get a proper reading when exhaust gasses are still relatively cold. My car would barely idle and wouldn't run properly at all during partial throttle. I think I shaved about 25,000 miles off my clutch trying to slip it off the line while trying to remain at WOT to engage open loop mode which ignores that sensor. It wasn't fun.

Front o2 sensor should fix your idle problem.

By the way I hope the sensor was either covered under warranty or ordered from www.subaruparts.com. They are the absolute cheapest I could find them.
