Stumbling from idle to about 2900?
 
Hi,

I did a few mods now I am stumbling from idle to about 2900rpm. Its not terribly slow but you can feel/hear it has a small stumble, like if it may be lean, until 2900 and then it pulls all the way up. Just looking to see if anyone here has any ideas.

Rig: 89 XJ
Rebuilt motor about 60k on it (Renix FI and Renix Head)
Borla header heat wraped
2.5" cat/catback
99+ intake manifold
Injectors from a 98
Fuel pressure right now 57psi trying to make up for lean condition
Taurus fan swap
Map adjuster set to 5.56 volts
Homebrew CAI w/relocated IAT sensor

Thanks,
JR

How long has it been since the fuel filter has been replaced? Hopefully it's something as simple as that.
