That'* why I asked. The o-rings are commonly overlooked. You probably have a high idle or a 'wandering' idle too, right?

I'll check the PCV. Actually, the car idles just fine and runs smooth as hell, that is why I can't figure this out. I'll keep checking things.....

Just a follow up-ran a couple bottles of Chevron Techron through the engine and it has not stalled or hesitated one bit. Hopefully, all is good to go.

If you are getting vacuum in the crankcase indicated by feeling sucking after removing the oil filler cap, that still needs to be addressed or it could eventually lead to seal failures. Did you check your pcv and o rings?

If you ran dry gas through and it cleared up..either you had a gummed up injector or a dirty fuel filter.

If it'* the fuel filter..it'* going to come back. You may want to replace it if it hasn't been done recently. ~$6
