FIRING ORDER OF 420 SEL MERCEDEZ BENZ 1991

Every radio has a different code. You will have to contact a Mercedes-Benz dealer to get the code for your particular radio. It MAY require removal of the radio to get the serial number.

Probably has 3 or 4 of them in the exhaust from the header down past the catalytic converter. Your check engine code should have stated which one. Anyway, an easy fix, might need special tool, check it out, Hope this helps.

If you mean the one going through the fire wall, cut it off an inch away from fire wall and join with connector and hose clamps from a parts store .

If different, some models, the hose terminates in the scuttle area behind the fire wall.

I remember on one, I had to reach in under dash to disconnect the hose end.

You may need to put the hood into it's service position to acess the end of the hose.

There is a release mechanism on the hood struts or the hinges so hood will stand straight up.

for 2.3L engine, Firing order 1-3-4-2, Distributor rotates clockwise

If its never been done, just due to age it would be good to due it and guides before any issues developp.

SOUND LIKE FUEL PUMP GOING BAD.

Needs a New Flasher. This is located in the center console somewhat near the ashtray.

the blue wire goes to the signal to tel the wiper to go up and down like turning on an amp. Look for a open terminal for antenna power signal.
