94 st idle/running issues Options

[Kennyb8709]

Car: 1994 st manual trans all stock apart from eBay intake on car prior to purchase 140k on the clock.

Background: car was purchased a month or two ago, immediate tune up was done (plugs wires cap and rotor valve cover gasket and pass window switch fixed) also installed HID's and a radio to demo to customers at my work. Car ran tip top for about 2 weeks.

Problem and symptoms: when starting and idle car idles at approximately 500 or lower RPMS. Car stall occasionally when idling after start up. For first few mins of low idle engine will not rev above 1k if I'm lucky. When car decides to cooperate (anywhere from one minute to five) she revs till red line however 1k to 2.5k severely bogs and its slow after 2.5k. Car has almost no power under load. Passing on the highway is next to impossible.

I need some help here people. Any ideas?

Open up your dizzy, and check your pickup. It might have gone bad. I know when mine did my symptoms were:
-Starting issues
-Rough idle
-Misfire
-Occasional dead cylinder
-Bogging down after 3k
-Bogging down under load

Although I had a check engine light for it but I never bothered to check it cause it had been stuck on for a year.
