2G MDP effects on EGR removal

[spyderdrifter]

So I recently bought a DC Sports strut bar (n/t version) for my spyder, that requires the battery to be lowered or moved (mine was already low enough), and modification to the MDP location. I know what all that entails and this post is not about that. However I've read about how the MDP is only related to the EGR. My real inquiry is this... I've done emissions delete on my current spyder, with 2G head and 6 bolt short block, twice in the past. I know for sure I did everything properly, I.e... removed all associated vacation lines, EGR valve and solenoid, charcoal canister and properly blocked and sealed the EGR ports on the manifold. After all this, I experienced a fluctuating idle both times that never stabilized. So if I do think the delete again, do I need to also remove the MDP and block the port, or does it even matter and my idle is associated to something else? I unplugged the MDP a little while ago just to see if my CEL would illuminate while driving and throw a code. I got the P1400 code, but no CEL. I'm fine with this since I k kw my light works, it's been on plenty of times for other issues and comes on like normal upon start ups. So with these conditions, should I be fine with removing the sensor and blocking the port so I can install the strut bar?


Edit: I didn't remove the EGR solenoid, but left it plugged in and removed the vacation line from it.

Do you have a afr gauge? I didn't see one on your profile. If not, I HIGHLY recommend you to get a wideband. But unplugging the mdp sensor will will cause you to run lean. It measures air pressure in the intake manifold. Just move your battery to the trunk. Just go to a electrical supply store and you can get battery cables CHEAP. Just reuse the ends.

Plus moving the battery to the trunk gives you more room to work under the hood.

Getting an AFR gauge is on my priority of parts to get. My battery is not a problem being under the hood either. While your info is good, such as the running lean part, none of that is what I really asked. Running a little lean right now is probably good since I think it runs rich anyway.

I re-read your post. did you check your bov dump tube? why do you think its running rich???

 

[spyderdrifter]

Why would I need to check the dump tube, that doesn't relate to anything here. My running rich thoughts are for unrelated things as well, such as my turbo.

The MDP isn't the cause of your idle problems and it will not cause you to run lean either. You can just unplug it you don't need to block it off unless you want to remove the sensor. The only negative effect would be the code or cel but it wont affect how it runs.

Which is what I've done. I blocked it since I had to remove it to get the strut bar mounted properly.
