My 92 22re was missing bad when it first cranked for 30 seconds to a minute here while back, then it would smooth out and run perfect.. I bought another truck and haven't run it in several weeks.. It now cranks up and misses bad for about 10 seconds and falls back dead.. it won't get past it, like it was doing.. I'm guessing whatever that was causing it has gotten worse.. I don't have a check engine light .. I even tried to see if there were stored codes and didn't find any.. Any ideas?

 

spark plugs?

 

spark plug gap?, timing, rat in the air filter, wires chewed through, oil low?, injector "O" ring bad? intake gasket gone, fuel bad, fuel filter all sugary, belts on way to tight, afm stuck open or closed(from rat in the intake) you never know untill you look into it man good luck

 

How do you figure it got worse... it's 10 seconds now and was 30 seconds before?
oh wait... now it dies?

bad gas (maybe add a pint or so of isopropyl alcohol to a half-tank)
fuel filter
cold start time switch
cold start injector
coolant temp switch
throttle position sensor
air flow meter
my favorite: vacuum leaks

 

YEP, now it dies.. It would straighten out.... I been gone a minute and just had time to check back in.. I might try and fool with some Sunday.. Spark plugs are fairly new but i changed them anyhow , made no difference..Fuel filter is a year old so i guess that's worth a try.. BOY i dread it.. Last one i put on was ., you know

 

AFM.......problem solved... It feels like i put a new motor in.. Its got more power than its had in a long time!
