I'm hoping someone can help diagnose a stalling issue with a 1994 b230ft that recently had the head gasket replaced by a local mechanic. Had a mysterious slowly-disappearing coolant issue, then total head gasket failure in the driveway. The car never overheated. Engine has 120,000 miles on it.
Had the head gasket replaced, head decked at a machine shop, got it back and it ran like new for a week or so. Then my wife was driving to work and it stalled at a stop sign. No stumbling, she just rolled to a stop and it shut off. She restarted it, drove it home.
It sat for a week, then I restarted it to see exactly what happened. It started perfectly, idled around 1600 for a few seconds, then dropped down to 1000 for about five minutes with a little bit of surging, then stalled when I touched the gas pedal. I unplugged the idle control valve connector, started it again, did the same thing immediately after the fan kicked on.
I installed a new Bosch idle control valve, started it, and same thing happened. Here's a video -- the fan comes on, and then the engine just stalls, as if the ignition is turned off. For about a minute it will not restart, as if there's no spark. Then after a couple minutes it will restart as if nothings wrong.
Anyone know what I should look at next? Oxygen sensor? Fuel pump?
Any suggestions are most appreciated!
