+1Lower IMRC leaks are very difficult to locate smoking probably will not pin point it.
I know Sapperfires car has a leak on one side but since he used starting spray and nothing happened he don't believe me. He has intermittent rough idle, intermittent rough start, intermittent CEL codes. Its a kinda common issue with our cars. I imagine first gens are more prone to it with the cardboard gaskets and all.
GMAN, drive your ass up here with my damn EVAP cans and I will look at your car for free. If you pick up 10' of VAC line then we can just hook your car to the gauge in mine and confirm if its a vac leak. I will go over the car and fix what I can. If the plenum has to be pulled then I will charge half of whatever a shop wants to charge..... or about 1/4 of what the dealer would want! :lol:
Hell, I have a perfect condition drivers side IMRC to head gasket as it was only the passenger side that was bad on mine.
