If the fuel pressure is not excessive and the chip is burned for the injectors id get a new O2 sensor first. Your O2 numbers dont add up to a constant 105 blm.

if its at idle 750-900rpm, your MAF numbers are way off as well as IAC....what MAF do you have? what chip? do you have a translator?

SP = timing

PU = injector pulse width [i think] or injector duty cycle

New fuel pump hot wire kit & o2 sensor 42 psi at rail vac line off . Looks like chip is old it says Lou's perf. 28-18 not sure when installed

IAC set low car has real bad idle no translator switched maf from other tta blm same

what O2 sensor did you just install and do you have another handy just to verify that its not a faulty 02....

The o2 is a bosch 12014 installed 2 days before ohio drove from ny. took out same o2 looked ok had put it in in may took to indy & back had bad intake leak repaired before ohio. car ran good some body checked in ohio told me blm was low ( my kids cars they drive i fix i go back to points & carb. this is new but fun i do have keys to all ) so on a steep learning curve. Thanks to All for help Bob

Are you sure those AF numbers are correct????? At idle you should see 5-7, NOT something in the 40's, That's your problem, now it's just a matter of tracking that down.
