'98 Nissan 200 SX

#1

‘Service Engine Soon’ light on. Codes I got from AutoZone handheld analyzer are:

PO 440 & two P1448’s. They could not specify exactly which components need to be replaced. Car bucks and jerks when accelerating, especially going uphill. If

I back off on the gas slightly it will shift and the rpm’s drop to normal level.

I can’t find a paper or online repair guide for this car and can’t afford to take it to a mechanic. The gas cap seems to be okay, but I don’t know where the purge solenoid or evap canister are. I’ve looked for disconnected vacuum lines, no luck. I need this car to get to work. Please help!
