Misfire from hell
#12
And yeah I might as well replace dizzy but would just like to make sure before I replace it. Because when I bought the car I drove it for a 1 hour and half trip and didnt do this at all. It was after me trying to fix it that it got like that.

And electronics tend to act up more the hotter they get.
The longer it goes on the more it will appear until it just fails to function at all.

This is the order in which everything happened:
Bought car had a misfire on idle and light throttle but barely noticeable. Drove fine but I could feel it.
changed spark plugs. Same.
Put c&l maf and drove bad. Misfire on idle and light and medium throttle.
checked for vacuum leaks, found one between upper and lower. Replaced it. Same .
put back stock maf, got better. Back to when I bought it.(but didnt drive it too much)
bought msd wires and ignition coil. Same. ( didnt drive it too much)
put 19lb Injectors, drove the same as before but then as car warmed up started getting bad similar to how it was with c&l maf.
Cleaned salt and pepper and put some fuel injector cleaner. Same
so I bought a new tfi module. But havent turned on the car since. I have been having a hard time getting it in timing.

Ok so we are making progress here. I replaced the module with a duralast. I know I know I know motorcraft is better. But at my auto parts it was either that or accel. And I heard accel tfi isnt thatgreat and it was like 20 bucks more and mine has lifetime warranty. But point is... the misfire while driving is gone(so far) its just misfire at idle and very low throttle. I am currently uploading video for you to hear it. So could it be pcv valve ? I have two pcv valves. No oil filler.

Does this occur the entire time the engine is idling or is it only till it warms up?
It sounds more like its hunting idle and less like a miss.
Do you know if it has a different cam in it? it could just be cam lope
but it definatly does not sound ignition related.
