I HAVE A 2001 GT AND WITH A BLOWN ENG. I PICKED UP A 2003 ENG THE INJECTORS ARE PINK IN COLOR AND MINE ARE THE TYPICAL ORANGE 19 LB. ARE THE PINK ONES THE SAME AND INTERCHANGE? ALSO THE 2003 ENG HAS A HEATED PCV WILL THIS BE A PROBLEM SINCE MY OLD ENG DOES NOT? I LIVE IN FLORIDA SO FREEZE IS NOT A ISSUE. THANKS. ROY

 

The pinks are 22# , I dont know about the heated PCV, sorry

 

First off, I have no idea why n00bs always have to write in all-capitals. It's the online equivalent to shouting and will only **** people off more than help you. Just because it's online doesn't mean your throw the years of grammar out.

As for your questions, the injectors would require a matching MAF and/or a retuned computer, do to their larger flow rate. As for the heated PCV, all 4.6s come w/ it, so I'm sure your 01 engine did too. However, even here in upstate NY I don't need it, and have been running a non-heated one just fine.

 

you'll need the yellow/orange top 19's or a tune. It'll run pig rich without a tune update for the larger injector size.

heated PCV won't matter. Use your old one.

 

I agree. They changed the MAF sensor in 2003, the same time they updated to 22's, so you have to change to the yellows, or else you'll be screwed, and it'll run like crap.

 

It was 2002 that the pink injectors started. Isn't that also when they went to the MAF with the IAT sensor built into it. Or was that 2001 that started doing that. I know 99-00 do not have the IAT in the maf.

 

I always thought it was 2003, but could be mistaken.

 

02 has pink tops for sure.
