injectors injectors injectors....
Hey still having issues with my injectors. My previous thread was this..
https://www.miataturbo.net/diy-turbo-discussion-14/injector-issue-46929/. but I made a mistake. Actually ALL injectors are firing wide open causing a buttload of fuel when KEY ON ENGINE OFF. I took a peak at the 1.6L service manual and traced the circuit. The PCM is the control side of the injector circuit. Power all the time but grounded via PCM. I checked the connectors with the multimeter and did not find a short to ground. I swapped the MSPNP to the stock oem PCM/ECU and it did NOT fire the injectors wide open at KEYON ENGINE OFF. I took a look at the DIYautotune miata quickstart guide and it didn't say anything else besides pulling the fuse and starting it pretty much. So I don't think I'm missing something obvious? I just literally had it repaired at diyautotune a month ago and did not touch anything else. This is why you don't used mspnp from unknowns folks... :) |

I haven't tried unplugging the TPS connector yet, I'm going to look up on why it would do that. Thats what I don't understand. Must be some aftermarket thing. I'll give that a shot tonight. Apparantly the VTPS mod has been done on the mspnp, but I have a stock manual TPS. I'll do a bit more fishing around and see what I can find, unless sometime explains it to me right here and now. ;)

update: Unplugged the TPS and it stopped flooding the cylinders. Weeeeird. Now I have a massive vacuum leak I have to find. :( |
