P1132... sputters after warm...

[Liberto]

now... one thing that just came to mind... i had green top injectors (two of them were broke) in my 98 motor but my 99 donor motor had grey top injectors... so i reused the grey top injectors and the 99 fuelrail pressure reg etc etc...mmaayybbee....?

did you ever get this figured out? I just put a 99 3.0L in my 98 and I am have the same problem. But I don't have any codes

don't think anyone has suggested just looking at all the spark plugs and wires? maybe i'm off here.... I've had some plug issues lately that imitate this same problem... working fine at first, after warm up getting misses! I come to find out a plug is cracked... this could also cause engine to run rich being as no detonation? should hear a ticking if spark is grounding to engine...

???

Just did this same swap on a 98 with a blown up 3.0 to 99 3.0 and have very rich condition with p1132 and p1153 codes. I also used the fpr fom the 99 and the injectors from the 99. Any updates would be great.

Edit long time lurker and have always found answers here!!!

Fixed! (for now)

I remowed the FPR and Fuel rail along with the injectors from the 99 engine and used the old ones from the 98 and it runs great. I only got a 5 mi test drive tonight but it ran up to 70mph which it never would have before. Plus no check engine light.

Ill pull codes after I drive it to work tomorrow (25mi round trip) and update my findings.
