Im planning on doing the 00VI swap in the spring, getting all the parts through the winter and doing the swap maybe over X-Mas break..if its kinda warm

Well I know Ill need a guide tube from a 5th gen, but Im throwing around the idea of totally taking out the EGR valve. Im not remotely worried about emissions, Im really worried about starting my car when the air it cold, and not haveing an idle problem. I know that the heat coming back into the EGR valve helps heat up the manifold air and helps warm up the engine...

Would I run into problems without the EGR valve in the car ?? Anyone in a cold climate, without EGR, can chime in here.

BTW: Guys with Pathfinder Throttle Body, do you have trouble with the cold start compared to the 4th gen TB ?? does it still kick up to about 1500 at start up, same as your 4th gen TB. ??

Im sure Ill have more questions...

 

The engine will run fine. You might get a CEL. I don't recommend it since it's illegal and you don't lose power and you pollute a lot more. NJ doesn't need anymore smog as it is.

If you want to change the TB, don't buy a PF TB-get a 02+ E-gas TB for cheap and modify it. Go check out the 3.5 sticky to see how to mod it. It's dam* near impossible to find a PF TB anyways.

 

Well I have one that Im buying...the thing is I want to know that the cold start idle will be ok wit it before I go and invest in it

I guess I can always sell it if I'm disapointed in it

I don't have an EGR and I'm in a cold climate.

 

and ? ...how does your car feel/react to cold starts ??

It doesn't start in the cold for ****... but you can't blame that on the EGR. This car is so modded who knows what is causing that. Probably the 3x more fuel that my injectors dump as compared to stock.

The EGR is there to reduce NOX emissions. It doesn't have anything to do with starting the vehicle. EGR isn't even used during cold starts. You won't notice any difference on starts with or without it.

 

I dont under stand the prob with cold starts and pathy TB .
Ive had my pathy TB for 3 years and it starts and idles like the stock starts high around 1500 and then settles down to idle.

I also have no egr get a code about once a month .An i also have a resister dont know whats thats doing for sure but person who put it on for me has a better idea he will try ......

 

I don't believe the PF TB has a fast cam/cold idle.

 

what i meant is i dont understand the probs people are haveing,because my car starts the same as my stock TB did.
I was the second person after mardi to use the pathy TB and like ive said ive had it for a few years and my cars been driven in -0 f weather and cars starts and ldles fine.

 

No egr, no problems. The only reason i did away with mine was because of the headers.

 

EGR isn't used in idle (warm or cold) nor is it used during WOT if it is working properly. If the valve is stuck open from carbon deposits then it could easily affect idle among other things.

 

i think joes idea will work, it looks great on paper. im also going to try it on a sr20de-t missing the egr.

 

Well with the Pathy TB, what do you guys do about the TPS ?? as for making it longer and programming it to the pathfinder TB ??

tell me what you guys did

With the pathfinder TB, am I still going to have the option of cruize control ??

I have no problem having CC with my pathy TB.

I dont see why you would have a problum it has two ears just like a 4th gen Tb

 

For some the cruise ear? or whatever either won't clear something on the IM or the cable isn't long enough. It depends on the adapter plate.
