I'm looking for ideas on what might be the problem here. If I've been doing some spirited driving for an extended time and then come to a complete stop, sometimes my engine will die.

Fuel tank level does not seem to affect this.
I've replaced plugs/coils

It only does this after spirited driving. Regular driving, or stop & go traffic, it does just fine.

Any thoughts?

 

fuel delivery? Compression? Cat converter? Just places to start

 

I've got it in for compression testing right now, so I'll find out if that's the case.

After I get it back from that, high flow cat is getting replaced with a resonated mid pipe, so that will eliminate that variable.

What are you thinking for fuel delivery that would only happen during spirited driving when coming to a stop?

 

engine is dying. the compression might come back ok.but it is dying slowly but surely.

Sorry to tell u the bad news

 

I was told by multiple people to clean the e-shaft sensor. o.O that might help.

 

Looks like the SSV is sticking some (not enough to throw a CEL). That could possibly be the culprit because it would happen after extended driving in the 6k+ range.

 

SSV o.O?
Silver Surfer Vaporizer?
Specialty Sports Venture
Sailing Ship Vessel
Southeastern Specialty Vehicles

that's me goggling the acronym.. I would had posted more but you get the point. I'm having same problem. that's why I'm curious.
