87 GT MAF converted

misfiring....

pulled the plugs and have a little gas on all the spark plugs some more than others. This is while the car is cold (Car actually somehow idled like this long as I feathered the gas)

havent replaced the wires and plugs yet, but have new ones on hand...just trying to make sense out of this first

Im at 10* timing with GT40P heads, maybe bump it up a little to 11 or 12?

thanks

Click to expand...

this one

MAF - Mustang Mass Air Conversion - StangNet - The Mustang Network

its been maf converted for a while now...just had this prob since the head swap

19lb injectors

by the way got it idling fine last night with new plugs and wires...but when I let off the gas after a small rev of maybe 3000 rpms it wants to stall out unless with the gas pedal I ease it back to idle (900 rpms)

its also slow to return to idle from a rev...does not surge, just returns slow

Well for the idling issues, check this thread, http://forums.stangnet.com/698148-help-me-create-surging-idle-checklist.html If you fix whats causing the idle problem, it might cure or at least help your other issue. As it sounds like air fuel delivery/ monitoring/ processing issues.
