1997 ford ranger. intermittent problem. happens every few days.
truck stalls. can be on the interstate or idling in a parking lot, doesn't matter.
runs rough for a few seconds, then stalls. might cough and pop, then starter cranks engine very easily as if no compression. will not start at all.
only have to wait 5-10 minutes, then starts up completely normal as if nothing happened. runs fine.
this started well after the check engine light came on last month. when this stalling problem started happening, got the engine codes and they said "running lean"
got a new O2 sensor. disconnected the battery during replacement, that cleared error codes. check engine light turned off.
light still off, but this problem still happens. must not have anything to do with the check engine light.
AutoZone says it's not the O2 sensor or Mass Airflow Sensor, because that wouldn't cause an intermittent problem. also rules out the fuel filter and fuel pump. doesn't know what intermittent problem could occur days apart.
the strange thing is, this all started when flushing the radiator. did it every few minutes (ran rough, stalled, died, wait a few minutes to start again) then after finished putting in the antifreeze it does it every few days now.
what could it be?
