PI intake swap on my TC

[fmansfield444]

Alright guys. My town car has been having a rough idle issue and is giving lean codes. So what I plan on doing for it in the near future is a PI intake swap and while I'm doing that I will be replacing other parts with new. I also hope that while I'm tearing into it I can get more access to the top o2 sensors to replace them as well.

I'm going to follow the sticky for this swap and there's a couple of other threads about it in mustang forums to provide more pictures etc.

I plan to get some parts from local yards so any 2001+ 4.6 will have PI intake, coolant tube, nipple, and anything else right? I also plan on replacing water pump, spark plugs, and cleaning the injectors while I'm in there.

One big question I have is will I need a tune for just the intake? I may plan a pi cam swap sometime soon too I have read that the pi cams will work with npi heads is this true?

I'm kinda on a tight budget so expensive parts like the intake will be used from a yard, while cheap stuff like coolant tube I'd prefer new. I am doing this swap now because I still have the plastic crossover tubed intake and I do notice a change in idle when spraying wd40 around intake so I'm thinking its leaking. Plus my o2 sensors are throwing codes and I hope to free up space to get them changed though I doubt it will help much. They're so tight back there!

Anyone know where I can buy the heater return line? Or more importantly the pi water pump nipple? I could most likely get a used line from the yard but I'm afraid I may damage the nipple tapping it out and I can't find them anywhere

Got the swap done today, all went well first try with no intake leaks. Used pi gaskets and blue rtv around coolant jackets. Was able to clean I lot of parts up and will doing the o2's tomorrow. I did notice that I have a slight miss now though. Probably a bad connection on a cop or injector ill look at it tomorrow. Very well could be an injector because all of my connectors to them were so brittle the clips broke right off. Will a miss cause a code right away so I can tell which cylinder to look at?

if the miss is total, but a minor miss probably won't.

Fixed the miss this morning, my cylinder 2 injector connector got vibrated off because the plastic clip broke. I fixed it with a zip tie and all is good now no miss or any leaks with the new intake. My exhaust tone is better sounding and i have more power

I'm glad I could help! I hope it runs like a boss now!
