94 Disco... hear a wierd tack tack tack sound sort of like a spark or electricac arc ... sounds like it is near the coil... but I can see any sparks or arcs. Engine all of a sudden is a little rough with noticable less power on acceleration. Sometimes it will stall like it is either fuel starved or air starved.
Air filter was dirty... replaced it. Put in new fuel filter too. Same issues and that sound is still there. Not constant no set rythm to it, but there every 3-4 seconds.
new water pump, fan clutch, thermostat, lower radiator hose, powersteering hoses(3), alternator and driveshaft rubber coupling.
1990 Toyota 4 Runner SR5 230k(fell on its side, left her my friend said it was still on when we took off, I was drunk. Came back, all fluids gone. Topped her off and she started right up.)
Thanks for the responses... traveling this week with limited time to reply...
Looked at night... saw small little sparks every now right on top of the coil between one of the coill terminals and the boot of the ignition wire that leads to the distrib.
Ordered a new coil... found a Bosch on sale for $60... New wires, and while I'm at it a new distrib cap and rotor. Hope that will fix it all. Plugs were new last year but may pull them while at it and hope to see some milk chocolate.
Spark Arc Sound, rough idel, sometimes stalls
