MAFS

also.. if you put an aftermarket intake on.. maybe one of your intake hoses popped off.. or even if you didnt put an aftermarket intake.. just an intake hose in general may have popped off.

got any friends with 240's nearby that you can try their mafs out? thats how i troubleshooted my problem. similar to yours

no aftermarket parts on it at all...but ill check clean the connector and check the intake and hoses tom....would this cause it to idle low constantly...cuz it started doin it out of no where...also what are the chances its the distributor?? how do i check the ecu to see if it will throw me anything?? thanks guys for everything.

Just pull the plug off, if corroded clean the connections with eletronic cleaner, very fine sandpaper on a screwdriver, let it dry, plug up and try to start..

make sure you have no vacum leaks anywherethat can cause it to do that

for sure the MAF though

go to a local junk yard and look for a MAF it shouldnt be more then $25.

if all else fails i would check the ecu for the heck of it to see which code pops up
