Hey guys and girl, hope all is well!
On my 96 cobra its missing. I know a guy who works at ford works for team mustang there. We went ahead and put in a couple new things and did some other stuff. We replaced the sparkplugs and wires, checked the mass flow air sensor and nothing happened I replaced the fuel pump last year so we replaced the fuel filter. Took it out and still started missing. The odd thing is that before it was missing around 5000rpms but not its around 5500 to 6000. Also on a side note if you give it full throttle it misses but 75% or whatever its not an issue...odd? We got back to his place and and took the ignition coils off his car and put them on mine and nothing happened, it was the exact same. So we eliminated sparkplugs, the wires, fuel filter and pump, airflow, and ignition coil. We now think its the PCM or a lose ground. Either way I'm going to be spending a lot of work. If its a PCM its about 500$ I heard and if its a ground it could be anywhere in the car,fun fun!

Anyhow thats my rant about my car missing. Take care!

Describe your miss a little better. Does it fall apart, or does it still pull but with a studder? How many miles on the car? Mods?

has a studder kinda like that pig from looney tunes,ha! But yes has a studder and has about 90k on it. and mods are only exhaust and 4:10 gear. Steve told me that ford tested the 4.6 motor and it lasted over a million miles, its on display some where. But yea 90k studder and exhaust and 4:10 gear

I suggest having a compression test done, to rule out loss compression.
