i am interested in purchasing this red 93 SHO automatic. i went to go look at it and when trying to start it it would crank over but only putter and etc as long as the starter was engaged. but eventually it started but ran like crap. and would only stay running if the gas pedal was pressed. could the MAF sensor be shot? or could the IAC be shot? or could it just be that these parts just need to be cleaned, the check engine light never came on.and the car has been sitting for 2yrs. so i would guess that has a little to do with it too. i want to know what you all think could be the problem.
