ANyone ever had this happen please help!
When I am stopped at a stop sign or whenever my 92 max SE 5-speed will just drop below idle way down to nearly dying then slowly catch and bump back up to idle then drop right again and repeat, sometime dying. this is when I have the cltuch pedal depressed, and foot on or off the break, mind I have VTCs knocking.
thanks for the help!

Check for vacuum leaks. I think the manual says to squeeze the PVC hose (big hose behind the intake manifold) and see if idle rises. If it does you have a leak. I tried this once on a whim and found the hose to be rock hard though... Alternatively you can try squirting carb cleaner around.
Also check the EGR valve for sticking. Put your fingers under it and see if the diaphragm moves freely.
Those are some of the simpler checks, but it might be harder to track down if this happens only intermittently and not all the time. Best to borrow a manual from the library or better yet buy one and go through the troubleshooting part. There's tons more components you can check but it's more than I can say here.
