50% of the time your injector problem is the adapters have rubbed against the intake manifold and there is a short.

I'll double check while I'm in there but I would guess that would cause lean / stumbling. This was pretty consisentently rich, at least as far as my wideband was concerned. Actually fouled the wideband O2 for a while until I burned out all the excess gas/carbon, then I started getting readings again.

Of course I couldn't find anyone in the paddock with a real scanner so I don't know what the computer was seeing.

On mine when the bare wire touched the manifold the injector just stuck on wide open.

And spend $50 on an OBD link code reader, best investment I ever made.

First of all, congratulations on getting the car back together. The paint color really is amazing. I hope you are every bit as happy as you thought you'd be. Aesthetically, it is a great example of a tastefully and well-modded Elise. Definitely get yourself an OBDII scanner. Cheap and and indispensable tool for people who tinker on their cars. Love the V6 mirrors, too. Were they difficult to install or were they just a bolt-on affair?

Thinking of K-swapping? Here's an idea of the cost involved.

I actually have a bluetooth scanner with an app on my phone but of course I forgot it. Prob the best import tuner in the state was also there at the rally and I could not for the life of me find him. So who knows, just a series of cricumstances.

Just a series of circumstances.

To be honest, that's what you should name this thread.

Or your car.

Just a simple bolt on.
Gave the car much more of the "Atomic Flee" look in people's rearview

After learning that the 12V is always hot and the computer controls the ground to activate the injector, that makes a lot more sense.
The times that the injectors went haywire don't really make sense though, with that theory (mainly while puttering along in traffic). Also 3 of the 4 plugs were totally fouled. The 4th was fine, so I'm still not sure it would be a grounding issue, but I'll throw some electrical tape around the pigtails regardless.

I'm going to send the injectors out to get cleaned, and I'll pull the plugs again after a couple hundred miles and see where we stand. Also it makes sense for injectors to stick seeing as they sat for 9 months.

FYI: this is the norm for transistor-switched circuits. It's much more common to switch the ground side of the load instead of the hot side.
