1998 v70 stalling issue

[surfbug1]

OK so I put an odb reader on this and got some codes

....

P0172 MAF sensor needs to be cleaned? Vac leak?

P0410 --- the air pump thing ....I guess I can hook up the diode to the circuit and fix. I thought I did this already, but maybe missed something. is there an easy plug in?

P0108 --- MAP sensor.....that's 70$ for aftermarket...will do this if still needed after (ECT and O2 sensors)

P0116---Engine coolant temp range fault
P0117---coolant ECT temp sensor fail.... put in an aftermarket sensor a few weeks ago, just now ordered a new Volvo factory sensor
temp out of range?

P0130 O2 sensor faults, ordered an upstream and downstream Bosch O2 sensors


P0300 misfires, general cylinder misfires
P0301 cyl 1 misfire (dunno why don't have P0303?)
P0302 cyl 2 mis
P0304 cyl 4 mis
P0305 cyl 5 misfire

Any added help or comments would be appreciated!

( I have O2 sensors, ECT and thermostat on order, will install on Saturday )
