95 LSS Stalling

[Mike Beckstead]

SOS! My 95 LSS has recently been stalling.Seems to be when warmed up.Could be
on the highway but usually going slow or stopped.I turn it off after stalling and it
starts right up as if nothing happened.Garages will not touch it as it runs well when
ever I bring it in.Any suggestions?

If you have a plastic upper manifold it could be internal coolant leak(EGR pipe heat breaks down the plastic, poor design)Check and see if you have started to lose small amounts of coolant in the overflow container. If you have, it just keeps getting worse. You will need to replace upper plastic manifold and gasket for starters.They only last 30 to 50 thou. You can also buy a kit to avoid future problems.(smaller EGR stove pipe with clearance, doesnt melt plastic.

Thanks for the info.Yes,there does seem to be a bit of coolant loss.I'll look into your
suggestions.

Might want to check the egr itself, if carboned up or sticking itt can cause a rough idle or intermittent coast down stall.
