New owner of "94" S420...first problem...
OK. I got the car. It had sat for about 6 months. I did both cap and rotors and plugs(ALL BOSCH) car ran great. I started it up. It sounded like it was going to stall but then it kicked up then the engine light came on. I thought it was old fuel. I used dry gas and nothing. I ran it down the highway for a few hours with injector cleaner. Nothing. A freind of mine said it sounded like a TPS. I think this year doesnt have this. My guess it was a mass air flow problem or sensor. When I get to about 1000rpm to about 1600rpm it stutters back and forth. After it pass 1600 it runs great. I am thinking about just spending the $250 on the mass air flow unit and hope it works. does this sound like a fix?
