MAF code po103, a2 121 cause? Flashing arrow po730?

Post by adventurer2112 »

Hi All,
96 850 glt Na. Car rough idle then died, several times. Unplugged maf to get home. Po103, a2 121. Cleaned maf, no joy. Unplugged maf to get home again.
Could intermittent Maf sensor failure have caused my previous multiple incidents flashing arrow po730 a1 322 limp home mode?
See previous posts. Tranny doesn't shift into 4 th, hard shifts into 3 Rd. I will put in junkyard maf tomorrow. Maybe that will take care of maf, hoping it will also positively affect the tranny shifting. Although I think I will still have to replace the tranny solenoids.
Thanks.
Jack

It does sound like the trans has issues, apart from the MAF problem. But give it a go, see what happens when you have a working MAF in there.
