Random misfire.
1995 SSEi.Runs good if not to count boost isn't going over +1.
Idle little to high ,but I think it'* because BCA isn't pulling all the way up.When I push it by hand ,Idle goes a little lower.
The question is ,I'm getting 3 and 5 misfire from time to time(I use Actron9145) and check engine after drive some time.
Also sometime(once a week) after city driving when car is hot in traffic and then park for 10-15 min it won't start unless I gently pump a gas while starting.It'* like starting on 3 or 4 cylinders,that'* how it feels.
The only code I pulled is quad module1 fault(don't remember actual # right now),
Any thoughts appreciated.

BCS changed with no boost changes .It'* BCA or vacuum leak.I didn't get to that yet.
I'll be getting another coils soon ,so will see if this is the problem.
Thanks for reply.

The park and having trouble starting leads me to think you should test fuel pressure. That could also explain some misfires.
On the quad driver IIRC there is one that controls, evap purge, TCC lockup and BCS. Wish I knew that when I shipped some parts last night. I would have tossed in a BCS for you to test.

was it) didn't work.Check engine was ON all the time.All this group is getting juice from same fuse on passenger site.
My was burned.I changed and smell from evap disappeared,EGR fault code disappeared and cruise works.Quad driver triggers fault I suspect somewhere around BCS or faulty ground somewhere because sometime check engine shows after driving over the bump,when car is shaked a little or on the pot hole.
I got one BCS from you before Bill.I think it'* not the problem,but you never know.
