So I am going to tackle a project for a friend and I am needing to know exact steps for removing the throttle body, also does it require a new gasket if you take it off to clean it. Just looking for a PDf or list of steps here and tools needed as far as specialty torx sizes. thanks.

The issue we are exploring is: Idle surge, stalls some, and even has slight surging at speed. her car has 180K miles on it as well. Replaced the plugs and wires already. New MAf too. So i am bringing my airbox to see if the seal is no good on hers between the box and the MAf/throttlebody housing. Also going to check the tightness of the intake bolts to make sure those arent sucking in air. Planning on pulling a couple of the plugs to check for rich or lean mixture. Throttle body reset, and taking off the throttle body and cleaning it. Thinking maybe the carbon/exhaust gas build up is causing a sealing issue making the car choke itself out and not keep a nice rev. Other than the idle and surging the car has no knocks, valve noise, or blowing of smoke so these cars are truly built to last.

Bought a mid 90's merc c280 that had a case of not keeping idle well and running insanley rich, cleaned throttle body up and it fixed a ton of issues, narrowed it down to a bad MAF sensor that i need to order, so i plan on using process of deduction to solve her issue.

thanks

I wish I was home to try this, but what would happen if the EGR was stuck open?

I know a stuck CLOSED EGR makes the car peppy, less throttle delay - but you get a CEL code. Seems like the stuck OPEN EGR would give you a code as well - but again, IF it was stuck OPEN, what would it act like? I was thinkiing I could yank the electrical connector off mine and jumper the valve to battery - holding it open; then I could see how the car would act.


(Zach and I are talking about the same car....)

This should take care of the "removal" ..

 

I always wonder about this little hidden jewel when "can't find it" comes along..

 

 

Good point. One more reason to keep the engine and tubing clean. It stays cooler and tends to crack less/later in life. Sitting on the back of the engine, it gets dirtier from road blow-up.

If this has failed, I understand it is a major issue. If I had one in-hand (not on my DD), I'll bet I could make a fix.

Oh, well.
