ok i know rag away, but i let my buddy convince me to plug his jet chip for his 6cyl jeep cherokee into the port on the computer of my 2000 R/T. bad idea i know! now the TPS and MAP sensors are throwing a code. The stealership is saying that i need to have the parameters reset on my computer for 75 bucks and maybe that will work. if id doesnt work, im out 75 bucks and i still have to replace the sensors. any suggestions?
