I just purchased a 1997 E 320 and received it yesterday. I drove it last night without a problem. Today while driving slowly my Check engine light with a message "engine electronics" Came on and the engine started running rough. Does anybody have an idea of where i should start looking? I know i should scan it but i do not own one, i will borrow one tomorrow. I checked the gas cap and it seems secure. Could it be injectors, coil, wires, or some sort of sensor? Thanks

I'm with Storm, you can rent (refundable deposit) an OBD-II scanner at a few major-chain auto parts stores, and then when you have the codes, google them for what they mean.

RE: ENGINE ELECTRONICS CHECK ENGINE LIGHT AND MESSAGE
With out the codes, we are just guessing. Could be a MAF sensor, oops, there goes $300. We would not want to stear you wrong. Autozone will read the codes for free even if they can't sell you the parts.

I got the same model, got it in 12/06. No problem till I got the oil changed this past sunday. I also filled up with regular for the first time and added a little STP. Next day I get the electronics message, but the car is still running ok. Took it to autozone; they checked the error code for free. Comes out: "Secondary intake fuel injector" While I was getting it read, another benz driver (E420) comes up; so I ask him if he ever got that warning. He says yes, and bets its something to do with the fuel cap or fuel system. I told him about the regular and the STP, he laughed and said, "that's it".

start with the MAF sensor, get a can of CRC mass air flow cleaner, its like 6.99 and take it apart your maf sensor in your air intake and spray it clean after that use a Qtip to clean it. after that if it goes away your...........well do i have to explain?
