Hey there, just bought this car yesterday. Left the lot, got some grub. Started her up and had a check engine light out of NOWHERE. So, car seems to drive fine, doesnt overheat or anything wierd. I took to a carquest, they used the code reader tester dealy and this is what came up
Large vacuum leak
Throttle linkage concern
Faulty IAC Valve
TPS signal faulty
Not sure which of these could be it, should I be worried about driving it and doing more damage?
