she's started idling rough
the other day my 89 l-98 just started idling rough. swinging from about 1200 rpm to 600 rpm. it was idling so rough that the car was almost shaking or quivering. weird, because i've never had an idle issue. could it be the ethanol additive that is being put in to gas now? i know when i first got the car, i found straight pins inserted in to the tps connector???
i removed them months ago and did not see any change in the idle. any ideas? the car has been through a complete tune-up. also, it has a new fuel pump and filter.

last November my 1989 started idling rough and hesitating. My injectors were replaced previousily when the car was throwing out codes, none this time so tried dry gas and injector cleaner. Nothing help so put it into storage for the winter. Started driving it late March, after a few fill ups the condition improved where its running like new.
Could be bad gas. Also never overlook the injectors but mine were throwing codes, neither of you are mentioning codes.
