Ok Boys.. My wagon is running rough... but here is the thing. If I start it and let it sit running for about 5 mins it seems to run a lot better. If I jump in and go it runs rough on low rpm and never really runs great even after it warms up. Is this the dreaded Optispark?

She got power on the high end but not on the low end almost to the point of stalling out.



Any thoughts Brother Wagon Lovers??

Had a similar issue and found a clogged EGR valve, but it was a TBI, not an LT1.
