Fuel Injection Throttle Switch replacement
I'm looking to replace the throttle switch on my 1993 190e 2.6L. My engine is running lean and will not pass emissions at 2500 RPM. The part number on my switch is 201 540 42 45, and online (ebay, amizon, google) I've only found it used, attached to the throttle body and for more than I'd like to pay. I've found several 201 540 56 45 for fairly cheap and the part looks exactly the same. Are these parts compatible? Does anyone have suggestions on where to buy this part?
Thanks
