Extremely Weak Idle
 

As I'm coming off the freeway, I stop at the light, and when I reach a stop, my car starts idling EXTREMELY unstably. The whole car is rocking hard enough to notice. When I give it gas at the green, it wants to quit, but once I get going (10 mph+) it smoothes back out to what I'm used to. When I get home (approx. 1 mile further), I check the fluids and the radiator fluid is bout empty. Now when I drive it, it's idle is extremely weak. I tried putting the stock computer back in, I found a vac line that came off, but it still idles terribly. Again, though, once I get going, it totally smooths out. Oh, I also noticed the pressure on my boost gauge is not building up anymore. And it seems to run a little better when I take off the vac lines going from the boost gauge and the blow off valve to the engine. Do you think I blew up the motor, or do you think another vac line came loose? How would I know if the motor's shot?

I had a similar rough idle problem with my n/a. I replaced the shutter valve @ the base of the carb, runs great now.

i have a similar problem, keep an eye on my thread too :)

too bad his is fuel injected, like mine, and i'm having a smiliar problem, it's not idling that bad it idles low and doesn't like warm startups, and all my vacuum lines are fine and i don't have a boost gauge in yet
