maybe first lambda sensor.... when busted the engine goes in an "emergency run" and will not let you go the way your 182 is supposed to go

Not sure as i'm no expert, when you get it hooked up to a computer at the stealers they should be able to tell sensor -problems. This reading out the comp. wo'nt cost you that much
