ok everyone heres the dilema i bought a 74 mm throttle body. which is not the plug and play... i was up untill 2 AM last night trying to figure out how to swap electronics... some parts interchange easilsy some dont... if anyone has ever done this please help!! or any advice plese let me know

 

I know many on here have done it...and I am sure you will get your answer soon.

 

hopefully sooner than later im going to need the car soon (superbowl party) so ill give it a few hours then im putting her back together

 

New problem... decided to put everything back together everything was great fired her up fine but WILL NOT IDLE. checked hoses clips wires, etc everything seemed fine took the TB off and noticed the gasket between the TB and the engine was somewhat shot starting to tatter... do you think that would stop my car from idling also its running to rich my buddy was behind the Xfire and noticed black smoke sputtering out. any thoughts ideas thanks?

 

Yes, I would expect a bad gasket to cause idling and fuel mixture problems.

 

and i suppose that wouldnt be an easy find.... do you think it would be possible to make my own somehow?

 

Most auto parts stores will sell different types of sheet gasket material you can cut out a new gasket. I would try to buy a premade gasket first. I did a quick check on Rockauto.com under mercedes SLK320 and they had a throttle body gasket for $1.79. I then checked Advance Auto online and they had throttle body gasket set for the Crossfire for $12.99.

 

ordered from napa in the mean time i ghetto rigged some corkrubber material o well it will hopefully last untill tuesday
