HELPP idle + shifting messed up!!! please look and add any info you have
 

so i had my brother buy a "performance chip" (i didn't have the pay pal account) from ebay and..... this is what he got: http://cgi.ebay.com/ws/eBayISAPI.dll...ksid=p3907.m29
and being my brother as soon as i got it he went and jammed it in the damn sensor MAP and tried running my car. by the time i got outside it was too late, the engine was running hot, the check engine light was on and it had trouble shifting out of gear not to mention when slowing down it would lurch into the lowest gear. SO PLEASEEEE PLEASE tell me what i can do i really don't want to buy a new MAP sensor, but for now I'm leaving the sensor plugged in overnight please let me know if there's an easy fix for this. i read online that if one of the sensors becomes disrupted then the car may go into a type of safety mode please tell me this is the case! javascript:void(opener.AddText('[sm\=bangbang.gif]')); self.focus(); javascript:void(opener.AddText('[sm\=smiley19.gif]')); self.focus(); javascript:void(opener.AddText('[sm\=smiley19.gif]')); self.focus();
