Ignition problem
 

I have built a MSIIe from scratch and have had it running on my Miata -90 for some time now. I'm running almost stand alone, OEM computer only control idle everything else by MS

I have made some modifications, I'm running optoinsulators for both CAS signals, and I use Joe P:s inverted output circuit for the ignitors. It have been running perfectly for several months but now I get a non wanted ignition when turning key. It only occurs when the car have been standing still for an hour or so. Some times the car run really bad after start up. I guess it run on two cylinders only. After a while the car run on all cylinders like normal! Hot starts are no problem.

I really need some help to solve this problem! I hate the sound and running on 2 cylinders can't be good for the car.
Thanks in advance!

Take your car to the proctologist, they are more versed in things pooping than us mechanics here.

Ok, bad naming of the topic. English is not my first language you know... Any usefull answers out there or should we just remove the thread?...

No, it's fine. We needed a thread about poop.

So when you said poop, did you mean "pop"?? I'm not familiar with the changes you made so forgive me for stating the obvious, but it sounds like you fried something. Ignitor, coil, etc...

you have leaky injectors btw.

His injectors and my rectal sphincter have that in common.

:) not to be confused with his penial sphincter?
