Re: 4.1 v8 injector resistance
They probably did check the pressure and it showed OK. The pressure however needs to be looked at while the glitch is happening. This isn't too easy as the gauge has to be secured somewhere where it can be seen during a test drive if the shop has no dyno. If the thing springs a leak the shop might just find out how good their insurance coverage is.
Bean, I Have a 1983 Coupe Deville 4.1 and my car is doing the exact same thing and i have changed everything you named im so upset - i hope someone can help
You might try running it with a pressure gauge while driving. Don't remember what you have for an evap cannistor, but if it is saturated or the tank pressure control valve is shot that could be part of your problem. Try taking your fuel tank cap loose. Fuel filter?
