Thanks for the tips... I have to say, I'm not too familiar with the vacuum system on this car. I've seen some lines here and there, mostly EGR firewall lines, etc. but should I be able to hit most of them with the carb spray with everything still in tact on the engine? Seems like to get to most anything, you have to remove half the components, and then it won't run for testing because it's apart
My guess is there's a vacuum leak. Either a hose or the intake manifold gasket. The weird vacuum actuator noises I'm hearing inside the car I think are telling of the problem. Sometimes it almost sounds like water gurgling they are so active... and that's without me touching the HVAC controls. Seems likely with the random missing issue, the surging idle, and the tendency to fall on it's face a little right off idle when I give the throttle a quick jab.
By the way, I have tried a new coil and tested the EGR valve as described here and both checked out just fine. Also replaced the PCV valve. Spark plugs are new, wires are not, but wires gave a perfectly smooth idle on my bro's ZX2, so I think they're ok. Might just have to spring for new ones to make absolutely sure, but money is super tight right now.
Thanks again.
