ok i bought a 1997 powerstroke cheap!!!! $500 guy was told the engine was toast by a shop because of excessive blowby which was do to a glow plug that blew the guts out of it fixed that and found some other issues

so here is what i know and what i have it is a cali model with code ab injectors two of which are not deflecting oil out of the spouts so i bought a set of used code aa injectors not knowing i had code ab injectors is there any reason i cant mix and match? im assuming thats not possible but is there any reason my truck wont run on the single shots when i have split shots?

any help would be greatly appreciated im stuck!!!!!!!!!!!!

 

you can not mix them, ABs are split shots and AAs are single shots. you should be able to run the AAs but it would require someone to tune a chip to run them.

 

i really dont wanna run a chip honestly i would rather use a tuner if possible if basically i need to change my pcm then to convert to single shots because of the cali crap

 

Don't think its as easy as just swapping a PCM.

Why a tuner over a chip? A chip is the best thing to run on a 7.3

 

just personal opinion honestly i find chips to be invasive upon the wiring of the pickup i would rather plug in tune and unplug

i did already change to the 2 bad splits out for the two singles and the truck still shook and smoked with no romp and no idle surge just bad vibration i uninstalled my tuner and the vibration was cut in half maybe if i swap all the singles in will any tuner rewrite the computer for singles?

 

They should be able to

 

thanks for the help ill change them all sometime this week i really need my truck back


ran contribution got 2 and 5 are bad but at idle my injcntr pres is 443 at idle and 760 at 2000rpm spiked at 800

my injection pressure regulator was 7 percent at idle and 10% at 2000rpm trying to figure out if this means i need a new hpop??


this info is old but i never found out if any of it was bad anyone know??

 

changed over to all ab injectors installed my superchip tuner and fired right up no shake gonna drive it day after tomorrow to see how it drives

 

Do yourself a favor and get rid of the superchip and it will run a lot better

 

what are some other brands that make tuners for the 97 years? the superchip was just free so i took it haha
