My 93 coupe 5.0 was running ok, but had recently developed an occasional stall, but would start back up and run fine. I started the car yesterday, and bluish smoke came out the exhaust, and the car surged like crazy. I shut it down and pulled the plugs. They are all fouled and smell like raw fuel.
My car is stock bottom end, AFR heads, GT 40 tubular intake, Anderson Ford cam, 24 lb injectors with correct C&L MAF.
I have the plugs out and upper intake off so I can't run KOER codes. I am thinking it's not a bad injector because all plugs are fouled, so maybe fuel pressure regulator or bad MAF (which was new 6 months ago and looks clean??)
When it stalled, I had to hold the gas to the floor (to shut off the injectors) to get it to start again.
Any thoughts on this?
Thanks, Chris
