ok i bought a 1997 powerstroke cheap 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!!!!!!!!!!!!
The injectors are different fuel volumes. On acceleration the mismatched injectors will be contributing differently to the system causing "misses". Also, the double pump of the injectors is most noticeable at idle. The AAs not designed to be fired twice in a row make a gnarly sounding engine.
well it shook bad with the stock splits in it i swapped out to the singles and fired it up tuner free and a little shake i installed my superchip tuner and no shake at all im gonna drive it day after tomorrow see how she runs and work some of the air out thanks for the help
If you can get a Federal PCM (about $100 and something in the NAW4-6 range) and re-pin the harness connector your truck will become very tune-able. Singles are more reliable and that splits PCM can fetch you $800-1000 to someone that is trying to keep a stock truck going.
well my dad installed a tuner for the wrong year when i first got my truck and it wiped my pcm clean i got a replacement one from autozone for about 120 did i put a federal one in it?? i have had no weird lights on everything works normal
The two PCMs are not interchangeable. The wires are in different places. Near the connector is a printed sticker. There are three letters and a number. What does yours say? Example, my old Cali PCM was a MME2.
well if they are not interchangeable i mush have got the right one haha but all i know is it was 100% better with the singles put in at an idle i still need to drive it though ill try with and without tuner
