Help! New Opti Installed....
I put a new opti spark in and everything is back together and when I start it it runs ruff for a few seconds then stalls
I've checked and everything is connected and the spark plug wires are right.
I don't know what else to look at or for.....
what'd I break now?!?!...

Mine did that too when I replaced my Opti and H2O pump -- turned out that I had forgotten to plug the MAF back in! :jester Check all electrical connections again!

Re: Help! New Opti Installed.... (94vette)
I've checked everything and it's all connected and what not
the motor turns over like it should with the coil inpluged but plug it in and it sounds like it's miss firing and out of time or something
Could I have messed up something installing the new opti?
Theres only one way for it to go on and it is lined up right on the gear pin... Could something be wrong with the new opti? or could it be the wrong part? (if that possible?)

Re: Help! New Opti Installed.... (bogus)
How could that happen? It only fits on one way as far as I know
It's still not running so I guess i'm gonna take it apart again and take the opti off again and see if I find anything... who knows

Re: Help! New Opti Installed.... (fullboogie)
Routing?? never thought of that
What do you mean exactly?
They were changed maybe 3 months ago and didn't really move much during the opti install so the routing of them didnt change.
What would I not want a plug wire near?

Re: Help! New Opti Installed.... (Michael21)
I meant to say that if you changed the cap along with the opti, could you have switched 2 or more plug wires around? That would certainly cause it to run like crap.

Re: Help! New Opti Installed.... (fullboogie)
The opti I put in came as one piece which is, well, everything I'm assuming, I assume that cause this is the first time i've ever seen an opti and what i took off the car looks just like the new part I put back on the car...

Michael, did you have to remove the spark plug wires from the old setup and install them on the new setup? If so, you may have put them in the wrong order.
