Ford Fairmont, 81 model 200 I6 with C4... (Loaded to the gills with emissions CRAP) The car has a just rebuilt carb Engine about a year old New plugs, all filters, and fuel pump New cap, rotor, wires, oil, gas, coil The car was sitting for a long time. We got it and changed all above and engine was new when the car was parked. Anyway, here's the issue... It was running beautiful at first (week or so), but it sat for a week and when we started it today, it ran fine for a minute then started stalling. Now it starts and runs fine, but if you load the engine at all, it dies instantly. It dies when you put it in gear, it dies if you turn the steering and load the pump at all. It is just gone weak all the sudden. Any, and I mean any, load kills it. Even if you double foot it with the rpms up to keep it running, it dies or skips a BIG beat if it doesn't die. Let the rpms drop and it's instantly dead. Starts back up fine, but then does the same thing if you load it. Ideas???
trash in fuel tank...fuel sending unit getting clogged up...setiment in tank is on bottom at start up but as pressure builds gets sucked up into screen shutting off fuel...just my .02 Jim maybe rubber fuel line collapse ...
We pulled the tank and seriously cleaned it out already. We replaced all rubber fuel line with the tank clean, and we flushed steel lines. New filter... Rebuilt carb, tuned in well and running great until now. I noticed the brake booster might have issue with vac leaks. Sometimes when you push the brakes and the booster activates, it roughs the idle. I wonder if it is possible that the leak in the booster grew suddenly and now it kills the engine when you load it... Whatever it is, it happened in an instant and now won't go away.
Maybe I should disconnect the vac source from the booster and plug it. If the problem is gone, then I know it's the booster diaphram. Anyone else experience these syptoms with a booster problem?
