Hello, I have a 1995 dakota with the 3.9l v6 automatic 4x4. The trouble I keep having is it keeps popping up a 32 egr check engine light code. Problem is I think it is just popping that up because it is running too lean. I can also feel a lean misfire under load. I have replaced my egr valve with a brand new one, replaced all vaccum lines, replaced cc ventilation filter and pcv valve, and checked the intake for leaks and there are none. I took off and cleaned all the injectors which seemed to help a little. I have not checked fuel pressure, but I am very sure its fine as I replaced the tank sending unit a year ago. The last thing i'm left to resort to is to take the v8 throttle body back off and put the stock v6 one back on as it must be getting too much air to compensate for. Although I am confused because That is a very common mod and I haven't heard of anyone having problems with it. But I can remember this problem started whenever I put the v8 tb on. Any help would be much appreciated. Thanks.

 

Possibly you disconnected one of the EGR hoses or wires. Start at the EGR, if needed possibly replace it.

 

I did replace the egr valve

 

I just had my mechanic test the fuel pressure and its a strong 40 psi at idle. And with everything I have tried he says most likely the pcm is shot.

 

So I guess my question is, is the v8 throttlebody too much air for the v6 motor? Or am I looking at needing to replace the pcm?

 

so I put the v6 throttlebody back on. It's been a month since i've done so and the code 32 has not come back. It runs better too. All I can say is that I had a negative experience with the v8 throttlebody swap and would NOT recommend it to anyone.
