Hi all, I just bought a 1994 e320, Great car and ive been searching these forums often to help me, Since i bought the car a week ago ive put a new k&N air filter , New bosch fuel filter , New bosch copper spark plugs, New plug wires.....

But the car still feels Sluggish at times ...other times it feels like a beast and flys....So from reading here i located the onboard diagnostics and it blinked 23 times . I dont know what pin 8 or pin so and so mean my car under the hood has
a built in led and a button and it blinked 23 times .......

So my question is what should i look at to fix this ..any 1 had this problem in the past?

 

no clues anybody? guess ill take 2 dealer...ive searched but cant find any resolution to this code. Thanks ne way

 

You've got the California diagnostics terminal, you're going to have to find the manual that deals with that specifically.

 

Thanks Buddy . this is what i found

So 23 flashes according to this guide is

Intake manifold pressure (in base module pressure sensor- B5/2) with engine
running too low/high

So what does this mean?

 

That is the question indeed. I'd guess (guess mind you, nothing more) that you may have an intake manifold gasket leak. I don't know how you'd go about testing/verifying that however. Should be something on the forum you can search for and get better info.

 

im thinking check it like you would a tire leak spray some water around seal and bolts and look 4 bubbles, IDK....

I really want to bring this car to life then get some pics up. But before i upgrade cosmeticly i want to make sure the engine is running good.

Thanks for your help Saijin_Naib

 

So after some research im guessing its the Map sensor or the voltage going to it. or the vaccum line leading from it

 

Well, that isn't TOO much to test right?

 

not much but i dont even know how to test voltage and Vacuum leak can be anywhere ...but ill try

 

so i figure ide post my results to help others in the future after 1 mechanic told me it was my EGR causing the code 23....And tons of others suggesting a vacuum leak ......
I replaced the egr cost 250$ did it myself, Mechanic wanted 500$....Did not fix problem ...

Brought it to my friends mechanic ended up being simple easy Map sensor

100$ part code is gone .....

Now after trying egr tube clean and replacing egr valve car starts and stalls 10 seconds later ...if i gas it when it wants to stall car stays running and works fine until next restart it wants to stall again ....any ideas?

 

I would recommend spraying around the manifold with brake cleaner or carb cleaner
