Moving the injectors certainly would be a good quick check, so I'd try that first and see what happens.

Pulled the plugs just now after running for a few days on the COPs, and the same symptoms are on the plugs, except now 2&4 look about right and 1&3 have a white looking ground strap. So same problem, but now leaner! It's not running rough like a boxer as it was before, or spewing black smoke from the tailpipe, but this is just as scary, or scarier since it's leaner. Hopefully I can get these pics up... Could the injectors being grounded constantly like they were before have damaged them in some way? That's really all I can think of, if they were still stuck open I would certainly have the same boxer idle and black smoke (and constant >11:1 AFRs) as I had before. Should I try moving the injectors around and see if the problem follows them? If you do send them off, you might mention that they were the victim of a wiring problem and a couple of them were grounded out for a bit. They might run some additional tests.... |
Unlikely, but you COULD measure the resistance across the injectors - also you could have damaged the drivers on the board. Or maybe your wires just got hot, shorted.
Keep us posted! |
hey did this ever get resolved? I am having the exact same problem right now. Car is a basically stock 97 and i am using the Braineack parallel install harness on an MS1v3. What is strange is that when I initially hooked it all up, it ran great with no tuning on the mspnp fuel+spark settings. Pretty much ran 13afr at idle and 14 - 15afrs cruising around the block. After that, I hooked up the WBo2 wire and fastened the case to the car, Then when i try to restart ... runs "like a busted subaru" and then I pulled the plugs and cyl 1 and 3 are black and 2 and 4 are white.

haha! Scott, learn how to solder (just kidding, your doing just fine)! I almost loled when i took a look at the wiring harness, one of the fuel injector wires had come undone, and therefore there was no fuel in two cylinders. Hooked it back up and I am back in business. Now I have an LC1 that actually works, and I am officially running megasquirt (again). Still need to work on the sensor bias settings though, AITs are reading about 30* lower than they should be. Oh well now it runs.
