I fixed the coolant issue, it was a bad coolant cap,but now a biggie. Yesterday out of the blue I started the car turned it off then turned it back on. It started surging, low idle 5-600 rpm sometimes wouldn't rev above 4000 rpm. At first my dad thought a bad vacuum hose. I sprayed starter fluid all over, with no increase in rpm. I've heard the crank or throttle position sensor can go bad. All help would be great.

I just worked on a '97 last week - wouldn't idle at all. As soon as I started spraying carb cleaner down into the throttle body it started getting better, so I removed and cleaned it thoroughly which fixed it. Commsnded idle is very low, barely above 600 when warm.
