The 190E 16v intake pipes setup
All
Do we still have 16v owners on this forum? Used to, back 10 years ago when I joined! However this post may be relevant to all Jetronic cars, I'm not sure as I haven't looked.
So, the intake pipe setup on the 16v is strange, is it not? Here are the bits that I see:
1 There's the main 4 large long metal intake pipes, fed via the throttle to the intake ports.
2 Then there's the four individual rubber pipes taking air from from the PCV (i.e. the camshaft cover) and also taking it from under the air flow sensor via the idle control valve, and feeding this air onto the injector surrounds and into the engine.
Isn't that weird? There are 2 totally separates routes for the air to get to the intake? And those 2 routes then become connected once the gas pedal is pushed, because they both feed from under the air flow sensor? Is it possible that they could suck air from each other?? Isn't the vacuum and air flow going to go all over the place? Has anyone ever seen any other cars with this sort of setup?
I ask because I am investigating why my 16v feels like it has poor throttle response in the first 1/2 second when you squeeze the gas. This is also a criticism I have read in magazines when the cars were brand new. I wonder if it's related? I want to try blocking off some of the pipes and see the difference it makes. Any thoughts?
