ok really weird (for me) someone els is probly gonna go "oh well duh".

 

 

ok so got the 1989 dl coupe running after head gaskit job and fired it up runns then dies dose this over and over well if you get it at about 2 or 3 grand it would run ok but you can hear it goin up and down in idle speed ever so slightly. well i searched and read about 4 or five threads and people point to the MAF or in my case AFM (same thing just diferent design) anywho so i go out pull the 2 little screws and unplug it looks good (see pics) well then i unhook the top part of the air box and look in it its got some oil on it but nothing biblical (large) and i figure what the hell and i try to start it. viola IT RUNS amazingly it runs beautifully i tap the gas and it dosent miss a beat and it idles just great. but now i cant figur out why it runns so good with no AFM its unpluged and the breather tube,hose,pleanum W/E its called is just open. i know the previous owner and i know the car ran fine when he had it untel the terminal intake gaskit failure. i have no idea what a headfailure wuld do to the AFM but for now i am gonna just runn it with the AFM unplugged as it runns so well.

 

 

 

 

 

 

PS i also eliminated the ports on the side of the exhaust ports under the engine (put plates over them) and eliminated the EGR. but other than that just a regular rebuild.

have you tried replacing or cleaning the AFM? that might get it running properly. i think many will run without the MAF or AFM plugged in.
