i have a 93 del sol that was an auto converted to maual, when i got the car it had dropped a ring.

i rebuilt a motor to put in the car and its a y7 block bored 40 over with p29 pistons
and a z6 head i am throwing codes 41(primary oxygen) and 10(intake air temp)

the car idles really low, it has a hesitation when revving at idle, and while driving the car sputters when you reach about 2500 and clears up at 2800

my oil pressure light flickers at idle but goes off when given gas

this is my only car and i need it to get back and forth to work

someone please help asap

 

I'm guessing your timming is off bc the sputtering. Or try replacing your o2 and iat sensor and see if that helps.
